Introduction
The FT-250E is an ultra compact FM hand-held providing up to five watts of RF power
and a wealth of convenient features for the 2m amateur band. The FT-250E has rubber
gasket seals around all external controls and connectors to help keep out dust and rain or
spray, assuring years of reliable operation even in harsh environments.
Sixteen multi-function keys provide the ultimate in programmability, with 199 freely tunable memories and two VFOs. All memories store repeater shifts or separate tx/rx frequencies, CTCSS (Continuous Tone Controlled Squelch System) or DCS status. You also
get one instant-recall “Home” channel memory and ten special purpose memories for
limited subband tuning/scanning. Busy channel band or selective memory scanning is
provided along with priority channel monitoring; 1 MHz up/down stepping; ARS (automatic repeater shift) when tuned to repeater subbands; plus a top panel rotary dial for
memory and frequency selection. The keypad serves as a DTMF encoder during transmission, and up to 9 DTMF memories can store 16 digits each for quick playback of commonly used numbers.
The liquid crystal display shows seven frequency digits, memory selection, CTCSS tone
frequency, and includes a bargraph S/PO meter. Yaesu’s power saver system can be set by
the operator for optimum sampling/standby ratio, or can be turned off for packet operation. And our new APO (Automatic Power Off) system shuts off the transceiver to avoid
dead batteries if you doze off or are called away unexpectedly.
Operation under difficult conditions is simplified by a lamp button illuminating the display
and backlit translucent keypad, diatonically assigned function-dependent keypad beeps.
Please read this manual carefully to gain a full understanding of the features of the
FT-250E.
RF Exposure Requirement
When transmitting, hold the radio in a vertical position with its microphone
2 inches (5 cm) away from your mouth and keep the antenna at least 2 inches
(5 cm) away from your head and body.
The radio must be used with a maximum operating duty cycle not exceeding
50%, in typical Push-to-Talk configurations. DO NOT transmit for more than
50% of total radio use time (50% duty cycle). Transmitting more than 50% of the
time can cause FCC RF exposure compliance requirements to be exceeded.
SAR (Specific Absorption Rate) compliance for body-worn use was only demonstrated for the supplied belt-clip. Other body-worn accessories or configurations
may NOT comply with the FCC RF exposure requirements and should be avoided.

to green. Even if the charging is completed, the LED indicator
will sometimes change to red for trickle charging.
Disconnect the pack from the CD-47 Desktop Charger and unplug the PA-43C or
PA-43U AC Adapter from the AC line outlet.
Important Notes!
Do not connect an improper AC Adapter. Use only the supplied PA-43C or PA-43U
AC Adapter.
Do not charge an improper battery (one not specifically designed for use in the
PA-43C or PA-43U, CD-47).
Disconnect the pack from the CD-47 Desktop Charger, and unplug the PA-43C or
PA-43U AC Adapter from the AC line outlet, when charging is completed.
The PA-43C or PA-43U AC Adapter and/or CD-47 Desktop Charger will generate a
moderate amount of heat during the charging process. This is a normal condition.
The PA-43C or PA-43U, CD-47 is designed for charging only, and is not designed
for operation (transmission/reception) of the transceiver.
Periodically wipe the charging terminals in the nest in the charger stand, using a dry
cloth, to ensure good connections between the charger and battery.
Perform the battery charging where the ambient temperature range +5 °C to +35 °C.
Charge out of this range could cause damage to the battery pack.

Caution!!
When charging a battery pack alone (not attached to the transceiver), do not allow any
metal object to short the terminals on top of the pack.
Do not allow any metal objects to short the terminals in the nest of the charger stand,
as a short-circuit could cause overheating of the charger circuitry.
ANTENNA INSTALLATION
The supplied antenna provides good results over the entire frequency range of the transceiver. However, for enhanced coverage in remote areas, an external mobile or base station antenna may prove beneficial.
To install the supplied antenna
Hold the bottom end of the antenna, then screw it onto the
mating connector on the transceiver until it is snug. Do not
over-tighten by use of extreme force.
Notes:
Never transmit without having an antenna connected.
When installing the supplied antenna, never hold the
upper part of the antenna while screwing it onto the
mating connector on the transceiver.
If using an external antenna for transmission, ensure that the SWR presented to the
transceiver is 1.5:1 or lower, to avoid excessive feedline loss.

Advanced Operation
VFO SPLIT MODE
For working on repeaters with odd splits, or communicating with astronauts on orbiting
space vehicles, it may be necessary to use non-standard splits between the receive and
transmit frequency. If the application is infrequent enough not to warrant the dedication of
a memory channel for this purpose, the “VFO Split” mode may be used. Here is the procedure:
Press the [VFO(PRI)] key, as needed, to select VFO-A. Set VFO-A for the receiving
frequency (for example, 144.950 MHz).
Now press the [VFO(PRI)] key, and set VFO-B for the desired transmit frequency
(e.g. 144.750 MHz).
Press the [VFO(PRI)] key once more to re-establish VFO-A as the “Main” (receive)
VFO.
Press the [F/L] key, then press the [0(SET)] key, to enter the Set mode.
Rotate the DIAL to select Menu #5 (“V-SPLIT”).
Press the [F/L] key, then rotate the DIAL to set this function ON.
Press the PTT key once to save the new setting and exit to normal operation.
You will now be operating in a Split mode. When you press the PTT key to transmit,
you will observe that VFO-A and VFO-B will reverse positions.The VFO selection
indicator “b” will blinks while the transceiver is transmitting, this means that the VFO
Split feature is now activated.
If you need to modify the VFO-B (transmit) frequency (for Doppler Shift correction,
etc.), just press the [VFO(PRI)] key, then make the necessary change, then press
[VFO(PRI)] key once more to restore VFO-A to the “receive VFO” position.
When
you have finished with Split operation, re-enter the Set mode, and set Menu #5
to OFF.
A split frequency pair set up via the VFO Split feature cannot be stored directly into
memory. You can, however, store odd frequency pairs using a different (slightly simpler)
procedure. See page 18.
RECEIVE BATTERY SAVER SETUP
An important feature of the FT-250E is its Receive Battery Saver, which “puts the radio
to sleep” for a time interval, periodically “waking it up” to check for activity. If somebody
is talking on the channel, the FT-250E will remain in the “active” mode, then resume its
“sleep” cycles. This feature significantly reduces quiescent battery drain, and you may
change the amount of “sleep” time between activity checks using the Menu System:
Press the [F/L] key, then press the [0(SET)] key to enter the Set mode.
Rotate the DIAL to select Menu Item #9 (“RX SAVE”).
Press the [F/L] key to enable adjustment of this Menu item.

When you have made your selection, press the PTT key to save the new setting and
exit to normal operation.
When you are operating on Packet, switch the Receive Battery Saver OFF, as the sleep
cycle may “collide” with the beginning of an incoming Packet transmission, causing
your TNC not to receive the full data burst. Likewise, during voice operation, part of the
first word of an incoming transmission may be cut off during (normal) Battery Saver
operation.
TX BATTERY SAVER
The FT-250E also includes a useful Transmit Battery Saver, which will automatically
lower the power output level when the last signal received was very strong. With the
Transmit Battery Saver, the automatic selection of Low Power operation conserves battery drain significantly.
To activate the Transmit Battery Saver:
Press the [F/L] key, then press the [0(SET)] key to enter the Set mode.
Rotate the DIAL to select Menu Item #10 (“TX SAVE”).
Press the [F/L] key to enable adjustment of this Menu item.
Rotate the DIAL so as to select ON (thus activating the Transmit Battery Saver).
When you have completed your selection, press the PTT key to save the new setting
and exit to normal operation.
KEYPAD/LCD ILLUMINATION
Your FT-250E includes a reddish illumination lamp which aids in nighttime operation.
Three options for activating the lamp are provided:
KEY :
Pressing any key (except PTT) causes the lamp to provide illumination for 5
seconds, after which the lamp will automatically shut off.
5SEC :
Pressing the LAMP switch momentarily causes the lamp to provide illumination for 5 seconds, after which the lamp will automatically shut off.
TOGGLE : Pressing the LAMP switch momentarily “Toggles” the lamp on and off. The
lamp will stay illuminated until you press the LAMP switch once more.

FT-250E OPERATING MANUAL
Advanced Operation
CTCSS OPERATION
Many repeater systems require that a very-low-frequency audio tone be superimposed on
your FM carrier in order to activate the repeater. This helps prevent false activation of the
repeater by radar or spurious signals from other transmitters. This tone system, called
“CTCSS” (Continuous Tone Coded Squelch System), is included in your FT-250E, and
is very easy to activate.
CTCSS setup involves two actions: setting the Tone Frequency and then setting of the
Tone Mode. These actions are set up by using the [1(SQ TYP)] and [2(CODE)] keys, or
Menu Items #25 and #26.
Press the [F/L] key, then immediately press the [1(SQ TYP)] key. This provides a
“Short-cut” to Menu #25 (“SQL TYP”).
Rotate the DIAL so that “T” appears on the display; this activates the CTCSS Encoder,
which allows repeater access.
You may notice an additional “DCS” icon appearing while you rotate the DIAL in this
step. We’ll discuss the Digital Code Squelch system shortly.
Rotation of the DIAL in step above will occasionally cause “SQ” to appear adjacent to the “T” icon. When “T SQ” appears, this means that the Tone SQuelch system
is active, which mutes your FT-250E’s receiver until it receives a call from another
radio sending out a matching CTCSS tone. This can help keep your radio quiet until a
specific call is received, which may be helpful while operating in congested areas.
When you have made your selection of the CTCSS tone mode, press the PTT key.
Press the [F/L] key, then immediately press the [2(CODE)] key. This provides a “Shortcut” to Menu #26 (“TN SET”).
This Menu selection allows setting of the CTCSS tone frequency to be used.
Rotate the DIAL until the display indicates the Tone Frequency you need to be using
(ask the repeater owner/operator if you don’t know the tone frequency).
Press the [F/L] key to save the new settings and exit to normal operation.

Advanced Operation
DCS OPERATION
Another form of tone access control is Digital Code Squelch, or DCS. It is a newer, more
advanced tone system which generally provides more immunity from false paging than
does CTCSS. The DCS Encoder/Decoder is built into your FT-250E, and operation is
very similar to that just described for CTCSS. Your repeater system may be configured for
DCS; if not, it is frequently quite useful in Simplex operation if your friend(s) use transceivers equipped with this advanced feature.
Just as in CTCSS operation, DCS requires that you set the Tone Mode to DCS and that
you select a tone code.
Press the [F/L] key, then immediately press the [1(SQ TYP)] key. This provides a
“Short-cut” to Menu #25 (“SQL TYP”).
Rotate the DIAL until “DCS” appears on the display; this activates the DCS Encoder/
Decoder.
When you have made your selection of the DCS mode, press the PTT key.
Press the [F/L] key, then immediately press the [2(CODE)] key. This provides a “Shortcut” to Menu #27 (“DCS SET”).
Rotate the DIAL to select the desired DCS Code (a three-digit number). Ask the repeater owner/operator if you don’t know DCS Code; if you are working simplex, just
set up the DCS Code to be the same as that used by your friend(s).
When you have made your selection, press the [F/L] key to save the new settings and
exit to normal operation.
Remember that the DCS is an Encode/Decode system, so your receiver will remain
muted until a matching DCS code is received on an incoming transmission. Switch the
DCS off when you’re just tuning around the band!

FT-250E OPERATING MANUAL
Advanced Operation
TONE SEARCH SCANNING
In operating situations where you don’t know the CTCSS or DCS tone being used by
another station or stations, you can command the radio to listen to the incoming signal and
scan in search of the tone being used. Two things must be remembered in this regard:
You must be sure that your repeater uses the same tone type (CTCSS vs. DCS).
Some repeaters do not pass the CTCSS tone; you may have to listen to the station(s)
transmitting on the repeater uplink (input) frequency in order to allow Tone Search
Scanning to work.
To scan for the tone in use:
Set the radio up for either CTCSS or DCS Decoder operation (see the previous discussion). In the case of CTCSS, “T SQ” will appear on the display; in the case of DCS,
“DCS” will appear on the display.
Press the [F/L] key, then immediately press the [2(CODE)] key to select the “TN SET”
Menu item (when TONE SQL is selected) or “DCS SET” (during DCS operation).
Press the [F/L] key, then press and hold in the [(MHz)] or [(MHz)] key to start
scanning for the incoming CTCSS or DCS tone/code.
When the radio detects the correct tone or code, it will halt on that tone/code, and
audio will be allowed to pass. Press the [F/L] key to lock in that tone/code.
Press the [F/L] key, then press the PTT key to save the new settings and exit to normal
operation.
If the Tone Scan feature does not detect a tone or code, it will continue to scan indefinitely. When this happens, it may be that the other station is not sending any tone. You
can press the PTT switch to halt the scan at any time.
CTCSS/DCS BELL OPERATION
During CTCSS Decode or DCS operation, you may set the FT-250E up such that a ringing “Bell” sound alerts you to the fact that a call is coming in. Here is the procedure for
activating the Bell will ring in accordance with this programming.
Set the transceiver up for CTCSS Decode (“TONE SQL”) or DCS operation, as described previously.
Adjust the operating frequency to the desired channel.
Press the [F/L] key, then press the [0(SET)] key to activate the Set mode.
Rotate the DIAL to select Menu Item #18 (“BELL”).
Press the [F/L] key to enable adjustment of the Bell ringer.
Rotate the DIAL to set the desired number of rings of the Bell. The available choices
are 1, 3, 5, or 8 rings, REPEAT (continuous ringing), or OFF.
Press the PTT key momentarily to save the new setting and exit to normal operation.
When a station calls you whose transceiver is sending a CTCSS tone or DCS code which
matches that set into your Decoder, the Bell will ring in accordance to this programming.
FT-250E OPERATING MANUAL

Memory Operation
The FT-250E provides a wide variety of memory system resources. These include:
199 “Standard” memory channels, numbered “1” through “199.”
A Home channel, allowing storage and quick recall of one prime frequency.
Five sets of band-edge memories also known as “Programming Memory Scan” channels, labeled “L1/U1” through “L5/U5”
MEMORY STORAGE
Select the desired frequency, while operating in the VFO mode. Be sure to set up any
desired CTCSS or DCS tones, as well as any desired repeater offset.
Press and hold in the [MR/MW(SKIP)] key for one second.
Within five seconds of releasing the [MR/MW(SKIP)] key, rotate the DIAL to select
the desired memory channel number.
Press the [MR/MW(SKIP)] key once more to store the frequency into memory.
You still will be operating in the “VFO” mode, so you may now enter other frequencies, and store them into additional memory locations, by repeating the above process.
STORING INDEPENDENT TRANSMIT FREQUENCIES (“ODD SPLITS”)
All memories can store an independent transmit frequency, for operation on repeaters
with non-standard shift. To do this:
Store the receive frequency using the method already described under MEMORY STORAGE (it doesn’t matter if a repeater offset is active).
Turn to the desired transmit frequency, then press and hold the [MR/MW(SKIP)] key for
one second.
Within
five seconds of releasing the [MR/MW(SKIP)] key, rotate the DIAL to select
the same memory channel number as used in step above.
Press and hold the PTT switch. Then while holding the PTT switch in, momentarily
press the [MR/MW(SKIP)] key once more (this does not key the transmitter).
Whenever you recall a memory which contains independently-stored transmit and receive frequencies, the “[–][+]” indication will appear in the display.
The “Odd Splits” feature permits setting TONE/DCS individually for transmit and receive. Briefly, press the [F/L] key, and then press the [2(CODE)] key. Rotate the DIAL
knob to select the TONE or DCS for receive. You can confirm the Transmit and receive
TONE/DCS by alternately pressing of the [REV(HOME)] key.
MEMORY RECALL
While operating in the VFO mode, press the [MR/MW(SKIP)] key. The “MR” indicator will show that you are now in the Memory Recall mode.
Rotate the DIAL to select the desired channel.
To return to the VFO mode, press the [VFO(PRI)] key.
An easy way to recall memories is to key in the memory channel number, then press
[MR/MW(SKIP)].
For example, to recall memory channel #16, press [1]-[6]-[MR/MW(SKIP)].
18
FT-250E OPERATING MANUAL
Memory Operation
MEMORY OFFSET TUNING
Once you have recalled a particular memory channel, you may easily tune off that channel, as though you were in the “VFO” mode.
With the FT-250E in the “MR” (Memory Recall) mode, select the desired memory
channel.
Now press the [MR/MW(SKIP)] key momentarily. The “MR” indicator will be blinking.
Rotate the DIAL, as desired, to tune to a new frequency. The synthesizer steps selected
for VFO operation on the current band will be the steps used during Memory Tuning.
If you wish to return to the original memory frequency, press the [MR/MW(SKIP)]
key momentarily. The “MR” indication will no longer be blinking.
If you wish to store a new frequency in the current or another memory. Just press and
hold the [MR/MW(SKIP)] key for one second, select the new memory channel (if
desired), and press [MR/MW(SKIP)] key again momentarily.
Any required CTCSS/DCS changes, or repeater offset modifications, must be done before storing the data into the new (or original) memory channel location.
HOME CHANNEL MEMORY
A special one-touch “HOME” channel is available, allowing quick recall of a favorite
operating frequency. Memory storage is simple to accomplish:
Change the setting of Menu Item #20 from “REV” to “HOME,” if it is not already set to
that option (see page 35).
Select the desired frequency, while operating in the VFO mode. Be sure to set up any
desired CTCSS or DCS tones, as well as any desired repeater offset.
Press and hold the [MR/MW(SKIP)] key for 1/2 second.
While the memory channel number is blinking, just press the [REV(HM)] key. The fre-
quency and other data (if any) will now be stored in the special HOME channel register.
To
recall the HOME channel, press the [REV(HM)] key momentarily while operating
in the VFO or MR mode.
LABELING MEMORIES
You may wish to append an alpha-numeric “Tag” (label) to a memory or memories, to aid
in recollection of the channel’s use (such as a club name, etc.). This is easily accomplished
using the Set mode.
Recall the memory channel on which you wish to append a label.
Press the [F/L] key, then press the [0(SET)] key, to enter the Menu mode.
Rotate the DIAL to select Menu #1 (“ALPHA”).
Press the [F/L] key to enable changing of this Menu item.
Press the [F/L] key, then press the [F/L] key again, to begin entry of the Label.

When you have programmed a label which is under 7 characters, press and hold in the
[F/L] key for one second to confirm the label (if the label is exactly 7 characters in
length, you do not need to press and hold in [F/L] key).
When you have completed the creation of the label, press the PTT to save the label and
exit to normal operation.
To activate Alphanumeric Tags:
Press the [F/L] key, then press the [6(A/N)] key.
Rotate the DIAL and select “ALPHA”.
When you have made your selection, press the PTT key to save the new setting and
exit to normal operation.
To
display the frequency again, select “FREQ” in step above.
MASKING MEMORIES
There may be situations where you want to “Mask” memories so they are not visible
during memory selection or scanning. For example, several memories used only in a city
you visit infrequently may be stored, then “Masked” until you visit that city, at which time
you can “Unmask” them for normal use.
Press the [MR/MW(SKIP)] key, if needed, to enter the MR mode.
Press and hold in the [MR/MW(SKIP)] key for 1/2 second, then rotate the DIAL to
select the memory channel to be “Masked” from view.
Press the [F/L] key. The display will revert to memory channel #1. If you rotate the
DIAL to the location you just “Masked,” you will observe that it is now invisible.
To
Unmask the hidden memory, repeat the above procedure: press and hold in the
[MR/MW(SKIP)] key for 1/2 second, rotate the DIAL to select the masked memory’s
number, then press [F/L] to restore the memory channel’s data.
MEMORY ONLY MODE
This allows operation only on stored memories, which are displayed by name (if any) at
the right, and the memory channel number to the left. No frequency is displayed, and only
“CH.nn” will appear if you haven’t assigned an Alphanumeric name to a memory.
Repeater shift and tone setting indicators are displayed in the Memory Only mode, although they cannot be changed.
Here is the procedure for activating the Memory Only mode:
Turn the radio off.
Press and hold the PTT and LAMP key while turning the radio on.
Rotate the DIAL to select “MEM.ONLY”.
Press the [F/L] key momentarily to initialize the radio.
Repeat the previous step to return to normal operation.
20
FT-250E OPERATING MANUAL
Scanning
The FT-250E allows you to scan just the memory channels, the entire operating band, or
a portion of that band. It will halt on signals encountered, so you can talk to the station(s)
on that frequency, if you like.
Scanning operation is basically the same in each of the above modes. Before you begin,
take a moment to select the way in which you would like the scanner to resume scanning
after it halts on a signal.
Setting the Scan Resume Technique
Three options for the Scan-Resume mode are available:
5 SEC: In this mode, the scanner will halt on a signal it encounters, and will hold there for
5 seconds. If you do not take action to disable the scanner within that time period,
the scanner will resume even if the stations are still active.
BUSY: In this mode, the scanner will halt on a signal it encounters. Two seconds after the
carrier has dropped because the other station(s) ceased transmission, the scanner
will resume.
HOLD: In this mode, the scanner will halt on a signal it encounters. It will not restart
automatically; you must manually re-initiate scanning if you wish to resume.
To set the Scan-Resume mode
Press the [F/L] key, then press the [0(SET)] key, to enter the Set mode.
Rotate the DIAL to select Menu #7 (“RESUME”).
Press the [F/L] key to enable changing of this Menu item.
Rotate the DIAL to select the desired scan-resume mode.
When you have made your selection, press the PTT key to save the new setting and
exit to normal operation.
The default condition for this Menu Item is “5 SEC”.
VFO SCANNING
This mode allows you to scan the entire current operating band.
Select the VFO mode by pressing the [VFO(PRI)] key, if necessary.
Press and hold in the [(MHz)] or [(MHz)] key for 1/2 second to start scanning.
If and when the scanner encounters a signal strong enough to open the squelch, the
scanner will halt temporarily; the decimal point of the frequency display will blink
during this “Pause” condition.
The scanner will then resume according to the Scan Resume selected in the previous
section.
To cancel scanning, press the PTT key.
If you want to change direction of the scan while it is underway, rotate the DIAL one
click in the opposite direction (in this case, one click counter-clockwise).
FT-250E OPERATING MANUAL
21
Scanning
MEMORY SCANNING
Memory scanning is similarly easy to initiate:
Set the radio to the Memory mode by pressing the [MR/MW(SKIP)] key, if necessary.
Press and hold in the [(MHz)] / [(MHz)] key for 1/2 second to initiate scanning.
As with VFO scanning, the scanner will halt on any signal encountered that is strong
enough to open the squelch; it will then resume scanning according to the Scan-Resume mode set previously.
To cancel scanning, press the PTT key.
HOW TO SKIP (OMIT) A CHANNEL DURING MEMORY SCAN OPERATION
When you have some very active channels stored in memories, you may wish to skip them
when scanning, but still have them available for manual selection.
Such channels may be “Skipped” during scanning, if you like:
Set the radio to the Memory Mode by pressing the [MR/MW(SKIP)] key, if necessary.
Rotate the DIAL to select the Memory Channel to be skipped during scanning.
Press the [F/L] key momentarily (not for 1/2 second), then press the [MR/MW(SKIP)]
key (momentarily). A small “SKIP” will appear to the LCD. indicating it is to be
ignored during scanning.
To re-institute the channel into the scanning loop, repeat the above three steps (the “Skipped”
channel will, of course, still be accessible via manual channel selection methods using the
DIAL in the MR mode).
PROGRAMMABLE (BAND LIMIT) MEMORY SCAN (PMS)
This feature allows you to set sub-band limits for either scanning or manual VFO operation. For example, you might wish to set up a limit (in North America) of 144.300 MHz to
148.000 MHz so as to prevent encroachment into the SSB/CW “Weak Signal” portion of
the band below 144.300 MHz. Here’s how to do this:
Set the radio to the VFO mode by pressing the [VFO(PRI)] key, if necessary.
Using the techniques learned earlier, store (per the above example) 144.300 MHz into
Memory Channel #L1 (the “L” designates the Lower sub-band limit).
Likewise, store 148.000 MHz into Memory Channel #U1 (the “U” designates the Upper sub-band limit).
Switch to the Memory mode by pressing the [MR/MW(SKIP)] key once, then rotate
the DIAL to select Memory Channel # L1.
Press the [MR/MW(SKIP)] key; the “MR” label will be blinking in the left-hand frequency of the display.
You may now rotate the DIAL, or begin scanning by pressing the [(MHz)] or [(MHz)]
key for 1/2 second. The transceiver will behave as though it is in the standard VFO
mode, but operation will be restricted to the range between Memory Channels L1 and U1.
Note: Five pairs of Band Limit memories, labeled L1/U1 through L5/U5 are available.

SMART SEARCH OPERATION
The Smart Search feature allows you to load frequencies automatically according to where
activity is encountered by your radio. When Smart Search is engaged, the transceiver will
search above and below your current frequency, storing active frequencies as it goes (without
stopping on them even momentarily); these frequencies are stored into a special Smart
Search memory bank, consisting of 31 memories (15 above the current frequency, 15
below the current frequency, plus the current frequency itself).
Two basic operating modes for Smart Search are available:
SINGLE:
In this mode, the transceiver will sweep the current band once in each direction starting on the current frequency. All channels where activity is present
will be loaded into the Smart Search memories; whether or not all 31 memories are filled, the search will stop after one sweep in each direction.
CONTINUE: In this mode, the transceiver will make one pass in each direction as with
One-Shot searching; if all 31 channels are not filled after the first sweep,
however, the radio will continue sweeping until they are all filled.

The FT-250E scanning features include a two-channel scanning capability which allows
you to operate on a VFO or Memory channel, while periodically checking a user-selectable Priority Channel for activity.
Here is the procedure for activating Priority Channel Dual Watch operation:
VFO (or HOME) - Memory
Recall the memory channel you wish to be the “Priority” Channel.
Set the radio to the VFO mode or HOME channel by pressing the [VFO(PRI)] or
[REV(HM)] key.
Press the [F/L] key momentarily (not for 1/2 second), then press the [VFO(PRI)] key
(momentarily). A small “PRI” notation will appear on the LCD.

FT-250E OPERATING MANUAL
ARTS (Automatic Range Transponder System) Operation
The ARTS feature uses DCS signaling to inform both parties when you and another ARTSequipped station are within communications range. This may be particularly useful during
Search-and Rescue situations, where is important to stay in contact with other members of
your group.
If the other radio is in range, the beeper will sound (if
enabled) and the display will show “IN RNG” as opposed to the out of range display “OUT RNG” in which
ARTS operation begins.
If you move out of range for more than one minute
(four pollings), your radio will sense that no signal
has been received, three beeps will sound, and the display will revert to “OUT RNG.” If you move back into range, your radio will again beep,
and the display will change back to the “IN RNG” indication.
You must terminate ARTS in order to resume normal operation. This is a safety feature
designed to prevent accidental loss of contact due to channel change, etc.
Here is how to activate ARTS:
BASIC ARTS SETUP AND OPERATION
Set your radio and the other radio(s) to the same DCS code number, per the discussion
on page 16.
Press [F/L] key, then press the [7(P1)] key* to activate the ARTS operation.
Press the [F/L] key. You will observe the “OUT RNG” display on the LCD. ARTS
operation has now commenced.
Every 15 seconds, your radio will transmit a “polling” call to the other station. When
that
station responds with its own ARTS polling signal, the display will change to “IN RNG” to
confirm that the other station “polling” code was received in response to yours.
Press the [F/L] key again to exit ARTS operation and resume normal functioning of
the transceiver.
*The “default” function of the [7(P1)] is “ARTS.”
If you are changed the [7(P1)] key assignment to another function described previously,
ARTS setup and operation procedure is following:
Press the [F/L] key, then press the [0(SET)] key to enter the Set mode.
Rotate the DIAL to select Menu Item #13 (“ARTS”).
Press the [F/L] key twice to active the ARTS operation.

ARTS (Automatic Range Transponder System) Operation
ARTS POLLING TIME OPTIONS
The ARTS feature may be programmed to poll every 15 seconds (default value) or 25
seconds. The default value provides maximum battery conservation, because the polling
signal is sent out less frequently. To change the polling interval:
Press the [F/L] key, then press the [0(SET)] key, to enter the Set mode.
Rotate the DIAL to select Menu #15 (“AR ITVL”).
Press the [F/L] key to enable changing of this Menu item.
Rotate the DIAL to select the desired polling interval (15 or 25 seconds).
When you have made your selection, press the PTT key to save the new setting and
exit to normal operation.
ARTS ALERT BEEP OPTIONS
The ARTS feature allows two kinds of alert beeps (with the additional option of turning
them off), so as to alert you to the current status of ARTS operation. Depending on your
location and the potential annoyance associated with frequent beeps, you may choose the
Beep mode which best suits your needs. The choices are:
IN RANGE:The beeps are issued only when the radio first confirms that you are within
range, but does not re-confirm with beeps thereafter.
ALWAYS: Every time a polling transmission is received from the other station, the alert
beeps will be heard.
ARB OFF: No alert beeps will be heard; you must look at the display to confirm current
ARTS status.
To set the ARTS Beep mode, use the following procedure:
Press the [F/L] key, then press the [0(SET)] key, to enter the Set mode.
Rotate the DIAL to select Menu #14 (“ARTS BP”).
Press the [F/L] key to enable changing of this Menu item.
Rotate the DIAL to select the desired ARTS Beep mode (see above).
When you have made your selection, press the PTT key to save the new setting and
exit to normal operation.
CW IDENTIFIER SETUP
The ARTS feature includes a CW identifier. Every ten minutes during ARTS operation,
the radio can be instructed to send “DE (your callsign) K” if this feature is enabled. The
callsign field may contain up to 16 characters.
Here’s how to program the CW Identifier:
Press the [F/L] key, then press the [0(SET)] key, to enter the Set mode.
Rotate the DIAL to select Menu #29 (“CW ID”).
Press the [F/L] key to enable changing of this Menu item.
28
FT-250E OPERATING MANUAL
ARTS (Automatic Range Transponder System) Operation
Press the [F/L] key, then press the [F/L] key again, to begin entry of the letters and
numbers in your callsign.

Interface of Packet TNCs & Reset
The FT-250E may be used for Packet operation, using the optional CT-44 microphone
adapter (available from your Yaesu dealer) for easy interconnection to commonly-available connectors wired to your TNC. You may also build your own cable using a fourconductor miniature phone plug, per the diagram below.
The audio level from the receiver to
the TNC may be adjusted by using the
VOL knob, as with voice operation.
The input level to the FT-250E from
the TNC should be adjusted at the
TNC side; the optimum input voltage
is approximately 5 mV at 2 k-Ohms.

so as to prevent voltage spikes from
possibly damaging your transceiver.
Also, be certain to turn off the Receiver Battery Saver, if activated (see page 10).
MICROPROCESSOR RESETTING
In the event that erratic, unpredictable transceiver operation is encountered, it is possible
that the microprocessor has sustained a static burst or other condition that has caused
corruption of some of its data. If this should happen, resetting of the microprocessor should
clear up the problem. Here is the procedure for resetting the microprocessor (this will
restore all factory defaults, and will erase all memories):
Turn the radio off.
Press and hold the PTT and LAMP key while turning the radio on.
Rotate the DIAL to select “ALL.RST” on the LCD.
Press the [F/L] key momentarily to initialize the radio.
SET MODE RESETTING
This “Reset” procedure restores the Menu (“Set mode”) settins to their factory defaults,
without affecting your regular memories.

Cloning
The FT-250E includes a convenient “Clone” feature, which allows the memory and configuration data from one transceiver to be transferred to another FT-250E. This can be
particularly useful when configuring a number of transceivers for a public service operation. Here is the procedure for Cloning one radio’s data to another:
Turn both radios off.
Connect the optional CT-27 cloning cable between the MIC/SP jacks of the two radios.
Press and hold the PTT and LAMP key while turning the radio on.
Rotate the DIAL to select “CLONE.”
Press the [F/L] key, to enter the CLONE mode. “CLONE” will appear on the displays
of both radios when the Clone mode is successfully activated in this step.
On the Destination radio, press the MONI key (“SAVING” will appear on the LCD).
Press the PTT key on the Source radio; “SENDING” will appear on the Source radio,
and the data is transferred.
If there is a problem during the cloning process, “C-ERROR” will be displayed. Check
your cable connections and battery voltage, and try again.
If the data transfer is successful, the Destination radio will return to normal operation;
Turn both radios off and disconnect the CT-27. You can then turn the radios back on,
and begin normal operation.
