The connection of cables may involve certain knowledge about the vehicle into which the unit will be installed. Consult with your car-dealer or
service station for more information if necessary, as we are not responsible for any damage this installation might cause to your vehicle.
1.
Be sure the vehicle has a negative-ground, 12VDC electric system before installation. Connect the provided DC cable with fuse-holder directly to the battery (red
cable to the positive terminal) to minimize any possible ignition noise. Be sure the
vehicle has a large capacity battery as the use of a transceiver may overload the
electric system of the vehicle.
2.
In addition, if the optional ignition-key ON/OFF feature is desired, use the provided
ACC cable. Remove the cover by unscrewing 4 screws. Connect the ACC cable to
the ACC power jack (CN11) on the rear side of the circuit board unit, position the
outgoing cable as shown above, select the ACC switch (SW11) to ACC position and
reassemble the cover.
3.
When installing, be sure to disconnect the battery cables of the vehicle and be sure
the ignition key is in the “OFF” position. Connect the ACC cable to the ACC terminal or ACC switch on the vehicle. Make sure the above sequence has been done
properly. Reconnect the vehicle’s electric system.
4.
If this option is selected, the unit can be turned on/off either manually or automatically in accordance with the ignition key position.
A: When the ignition key is turned to ACC or ON (“run”) position with the unit left
turned ON, the unit will turn on automatically and turns OFF when the ignition
key is turned to the OFF position.
B: To manually turn the power on/off, leave the ignition key in the ACC position
and use the PWR switch on the unit. If the ignition key is in the OFF position the
unit won't turn on. The power consumption of this feature is about 5mA regardless of the ignition key position. For operation without this option, always use
the PWR switch to turn the unit on/off and set SW11 to “on”.

Initial Installation
Power supply voltage display function
After connecting the transceiver to a power supply, the supply voltage can be confirmed by pressing the SQL key together with the FUNC key. The supply voltage to the transceiver is then seen on
the display.
The transceiver will return to its normal display when any key is pressed.
The display immediately changes as the voltage supply changes.
It also displays voltage during transmission.
(Example) In case of 13.6V
IMPORTANT: The range of the displayed voltage is only from 7 - 16VDC. Because the displayed
value is estimated, please use a voltmeter when a more precise reading is desired.

Basic Operations
VFO mode
VFO tuning is set as the default mode at the factory. VFO
(variable frequency oscillator) allows you to change the frequency in accordance with the selected channel step as you
rotate the main dial or by using the UP/DOWN keys on the
microphone. VFO mode is also used to program the data to
be stored in the memory channels or to change the parameter
settings of the transceiver.

Selective Communication
Many repeaters require a CTCSS tone or a DCS encode setting as a “key” to access a repeater
system, or a receiver using CTCSS or DCS squelch, so-called “selective-calling”. Sometimes,
CTCSS or DCS decode features are used on the output of a repeater so they can be used to open a
squelch. In this mode, regardless of the main squelch status, the audio can be heard ONLY when
the matching tone/code signal is received. The combination of CTCSS squelch and DCS function
is not available; only one or the other may be used for a given frequency.
Tone-squelch (CTCSS) and DCS
1.
Press TS/DCS key. The current setting will be
displayed with T/SQ/DCS icons and relative
frequency/code. Press the same key to select
T/SQ/DCS setting.
2.
The numbers (such as 88.5) represent the
CTCSS frequency in Hz. When it is displayed
with the T icon only, the unit transmits the subaudible tone while the PTT is pressed (encode)
and the repeater access is enabled (assuming
the repeater is using 88.5).
3.
Press the same key again so that the SQ icon
shows up on the display. This is the CTCSS
decode frequency. This enables CTCSS squelch
(or Tone Squelch, TSQ).
4.
Press it again so that the 3-digit number and
DCS icon is displayed. This is the DCS code,
and it enables DCS encoding and decoding.

For 2-4, rotate the main dial or press the UP/DOWN keys to change the tone or the code. Press any
key (Except TS/DCS, or Mic UP/DOWN keys) to enter the setting and return to the original status.
The T/SQ/DCS icon will remain on the display to show the current status. To exit, simply use the
TS/DCS key and press it until the relative status icon T/TQ/DCS disappears.
The CTCSS encoding and decoding frequencies may be set differently. The encode setting frequency automatically relates to the decode setting, but the decode setting does not affect encode.
The standard set of 38 different CTCSS tones are available as shown on the chart below. DCS
encode/decode cannot be separated and are selectable from 105 codes as shown below and on the

DET setting
If the DET mode in DCS operation is preferred, press the H/L key while the DCS code is displayed
in the setting mode. Observe that a decimal point appears, then follow the remaining sequence to
set the parameter and exit.
DET on DCS function stands for Detect-Only mode. In DCS operation, the TX signal carries a
digital code such as 001010000 as determined by setting the 3-digit code such as 123,124 etc. This
stream is modulated with a very low sub-audible frequency. The RX side, just like TSQ, detects this
stream and determines the squelch operation. This DCS code stream is transmitted all the way
through the communication like a CTCSS tone (in this case a single continuous tone, instead of
digital coded stream).
It is necessary for receiver to correctly and CONTINUOUSLY receive this DCS digital stream to
hold the squelch open, otherwise the CPU thinks that the signal is unwanted and it closes the
squelch. But due to noise or weak signal strength etc, sometimes it is difficult to continuously
receive a DCS stream. By activating DET, the receiver opens the squelch when the first corresponding DCS stream is received, then thereafter, regardless of the status of the DCS codes, the
DCS squelch remains opened.
Advantage of DET
It enables DCS squelch operation even in poorer conditions, opening the squelch only when
a corresponding DCS coded signal is received.
Disadvantage of DET
When it is activated, suppose 2 stations are sharing the same channel and using the DCS
selective-calling technique and transmitting at the same time. After station A with its corresponding DCS is gone, you may still hear station B, although he can't open your DCS
squelch by his signal alone.

IMPORTANT: When reception frequencies fall in any one of the formulas below, the unit may
receive a non-modulated signal.
This is due to the structure of frequencies of this unit and not a malfunction of the
unit.
• (Reception frequency on the MAIN side - 45.1MHz )
= Reception frequency on the SUB side - 43.4MHz (In u-u)
• (FM reception frequency + 10.7MHz) x 4 = UHF reception frequency - 90.2MHz
• (FM reception frequency + 10.7MHz) x 5 = UHF reception frequency
• (UHF reception frequency - 45.1MHz) x 2
- (VHF reception frequency - 21.7MHz) x 6 = 45.1MHz
• (UHF reception frequency - 45.1MHz) - (VHF reception frequency - 21.7MHz) x 3
= 21.7MHz
