Warning notes
Congratulations. HP 125-K/HP 425-K is an advanced PMR
(Professional Mobile Radio). Its rugged design allows it to be your
reliable partner even during hard working days. Its large LCD as well
as user friendly controls make the maximum ease of use.
HP 125-K/HP 425-K is a real system radio, supporting CTCSS/DCS,
5 tone signalling systems (encoder/decoder up to 28 + 28 tones),
FFSK, DTMF and trunking system property. Selcall mode supports
also many facilities, such as an alphanumeric address book, a call
queue function as well as a status message table. You can also use
FFSK to send/receive short text messages which you can dial via the
alphanumeric keypad. The way your radio operates may be upgraded
and may differ from what is described here.
To extend the flexibility the radio is provided with VOX function, which
allows to switch the transmission just by talking in full hands free
condition.
Since standard operation can be changed by programming, the
functions the radio includes and the buttons used to activate them
can be modified. For this reason some commands couldn’t be
available. Please contact your radio network administrator or dealer
for further details.
Transceiver’s specifications provided in HP 125-K/HP 425-K are
compliant with ETS 300 086 and ETS 300 113, moreover its top level
design and resistance are compliant with IEC529 level IP54 and MIL
STD 810 C,D,E.
CTE International is committed to continuous quality improve, for this
reason specifications may vary without prior notice.
Every effort has been made to ensure that the information in this
document is complete, accurate, and up-to-date. CTE International
assumes no responsibility for the results of errors beyond its control.
The manufacturer of this equipment also cannot guarantee that
changes in the equipment made by non authorized people will not
affect the applicability of the information in it.
This user’s guide is subject to change without notification. This booklet

Safety
Your HP 125-K/HP 425-K handheld transceiver has been carefully
designed to give you years of safe, reliable performance. As with all
electrical equipment, however, there are a few basic precautions you
should take to avoid hurting yourself or damaging the radio:
• Read the instructions in this handbook carefully. Be sure to save
it for future reference.
• Read and follow all warning and instruction labels on the radio
itself.
• Don’t carry the transceiver by the antenna. This may damage
the antenna or antenna terminal. Grasp it by its base (not the tip!)
when you need to place or remove it.
• Don’t keep the radio with the antenna very close to, or touching
exposed parts of the body, while transmitting. The radio will perform
best if the microphone is 5-10 cm away from the mouth and the
radio is vertical.
• Be sure the PTT key is not depressed when you don’t need to
transmit.
• Do not operate the radio near unshielded electrical blasting caps

Basic Operations
Basic Operations
This section describes how the standard operations work. Standard
operation can be changed by programming, moreover the functions
the radio includes can be modified via an IBM compatible PC. For
this reason the way your radio operates may be upgraded and may
slightly differ from what is described here.
2
IMPORTANT: Due to the full programmability of the radio, certain
menu commands could be unavailable. E.g. if your radio hasn’t
been programmed for selective call operations, the related menu
commands won’t be recalled. In case of doubts please contact
your dealer/radio network administrator for further details.
Reception
To switch the radio on:
Your radio could be previously programmed to work, channel by
channel, in “Open traffic”, “CTCSS/DCS” or “Selcall” mode. Please
have a look to each description and ask your radio network manager
or dealer which mode your radio channels work.
• OPEN TRAFFIC: in this case you will hear any communication
which will be transmitted on the selected channel. When any signal
is received your squelch will unmute and you will see in the LCD
(speaker enabled), (squelch is open),
(reception
the icon
field strength level – the number of bars will vary according to
the received RX strength). Moreover you will see the status LED
glowing green and you will hear the message.
• CTCSS/DCS (Continuous Tone Code Squelch System - Digital
Coded Squelch): they are systems which use particular TX signalling
(a continuous sub audio tone for CTCSS or a digital code for DCS)
as an access “key” to work a repeater (encoder) or to unlock the
party’s signalling sensitive squelch. This last condition allows to
share more radio networks in the same frequency. In this case
you will receive only messages coming from parties sending a
proper TX signalling. Please see the chapter “Selcall Operation”
for further details.
• SELCALL (Selective call): it’s a system which uses a signalling
sequence (e.g. audio tones for “5 tones” and DTMF selcall or a
frequency shift signalling for FFSK) to call a particular station or
group(s). In this case you will receive only calls provided with your
identification selective call code (a number) or calls sent to the
group you own. For further details please see the chapter “Selcall
operation”.

will start an autotest showing in sequence:
• A welcome message (if previously programmed – it is usually
your company name or your personal station identification). At
the same time all the LCD icons will be shown for one second
as LCD test.
• The firmware release number (FW Rev.).
2) After the autotest has been carried out the LCD will steadily show
the following data:

network in the same frequency, however they are just useful
to avoid disturbing stations not owning of the same network
with messages not related to them. In any case, if more than
one station is transmitting at the same time, this will cause
an interference. Don’t transmit if the status LED is glowing
or the icon is on the LCD. Wait till nobody is transmitting
on the channel.
Adjusting volume
When no keys are pressed for 5 seconds, the radio is in its normal
condition (stand by) and the
(up) and
(down) keys are used
to adjust the RX volume: just repeatedly press the key to increase
provided in the bottom
or the key to reduce it. The bar meter
part of the LCD will continuously show the volume level; as many
bars you will see, as higher is the volume level currently selected.
2
You will later see that up and down keys are also used to adjust
other settings recalled by pressing once or more times the MENU
key. This key is used to access the command menu.
Channel selection
If your radio has been programmed with more than one channel you
can easily change it. As previously explained each channel is identified
by alphanumeric names which are previously defined by your network
manager or supplier. They should have designated appropriate names
for them in order to make easier for you quickly recognizing which
channel you are currently working in.
To select a channel:
Channel

Basic Operations
1) Press the MENU key in order to access the command menu and
see on the display the message Channel. Normally you have to
press the key just once, but if necessary repeatedly press it again.
2) Press the
key to increase the channel number or the
key to decrease it.
3) Press the MENU key repeatedly to go through the next menu item
or press and hold to go to the previous menu item, or press the
(clear) key to escape the menu and restore the normal LCD
condition.
2
After 5 seconds, if you are not pressing any key, the menu is
automatically escaped, so the display will automatically revert to
its normal condition.
Adjusting squelch
Squelch device provide to silence your radio when you are working
in open traffic mode (please see “Reception”) and no signals are
received. It’s very important to adjust it in order to set the minimum
level which assures you a stable silence in stand-by condition. If the
squelch level is too high, you might lose weak signals. A good squelch
adjustment assures also a proper scanning operation.
To adjust the squelch:
1) Ensure that no communications are carried out in the tuned channel
(the icon shouldn’t be present in the top right part of the LCD).
2) Repeatedly press the MENU key in order to access the command
menu and see on the display the message Squelch (normally
you have to press the key twice). You will also see a number which
is the squelch adjustment level.

5) Repeatedly press the MENU key repeatedly to go through the
next menu item or press and hold to go to the previous menu
item, or press the
(clear) key to escape the menu and restore
the normal LCD condition.
2
After 5 seconds, if you are not pressing any key, the menu is
automatically escaped, so the display will automatically revert to
its normal condition.
2
In case of either CTCSS or Selcall system programmed, squelch
could not affect the loudspeaker status, because the radio is closed
awaiting the right tones. In case of advanced signalling systems,
please, pay attention to the programming of the monitor key
function (further described). Depending on this, you can or not
press the
button to mute/unmute the loudspeaker and to adjust
the squelch level. The set squelch level will be stored and recovered
at every switch on operation.
Transmission
When you need to transmit please get used to follow all these steps:
1) Ensure that the channel is not busy (otherwise you will create an
interference, please wait till that condition).
2) Press the PTT key: the status LED will glow red.
3) Start talking at a normal voice level at approximately 10 cm from
the microphone (keep the PTT key pressed).
4) When your message is over, release the PTT
2
Don’t shout! It won’t increase the distance range, but rather will
make you heard distorted.
2
Don’t release the PTT before your message is over or start talking
before pressing it, otherwise your message will be “chopped”.
2
A PMR handheld radio doesn’t normally allow to talk and receive
simultaneously, for this reason make your messages with a
reasonable time. When you are talking the other parties can’t do
that, so don’t occupy too much the channel. Use the common
sense.
2
The radio might be programmed with a timeout timer which
automatically put your radio in reception if you talk too much (after
a preset time). In this case release the PTT and wait for few seconds:
the radio TX features will be automatically restored. Ask the network
responsible or your dealer for further details.

Adjusting transmission Power
Adjusting display contrast
Your HP 125-K/HP 425-K can transmit with two power levels according
to the distance of your party station(s). Low and High levels can be
defined by default during programming, however we do recommend,
when possible, to use the Low power: it will increase the battery duty
and will reduce the risk to make interference with stations not owning
to your radio network which may sharing the same channel with you.
1) Repeatedly press the MENU key in order to access the command
menu and see on the display the message Power (normally you
have to press the key three times). You will also see a cursor on
either L or H.
You can adjust the LCD contrast in order to obtain the best readability.
It will vary depending on your use as well as the environment
illumination.

In both cases you will see Scanning and the channel names cycling
continuously. The scanning starts from the lowest address number
toward the highest. Obviously, if one or more priority channels
have been programmed, it will start from the first priority address
number.
3) To stop channel scan Press the MENU key,
or the PTT.
2
If you are working in Open traffic (please see the paragraph
“Reception”) ensure that the squelch is properly set, otherwise
the scanning may not properly work. See eventually the paragraph
“Adjusting squelch” for more details.
2
If CTCSS/DCS or Selcall have been previously programmed, the
scanning will stop only if the received signal has the appropriate
signalling.
2
If you press the PTT during channel scan (on the LCD) it will stop
and transmit in the priority channel or in the first available vacant
channel, depending on programming.
2
Channel scan can be programmed by your radio network
administrator or dealer in a variety of different parameters depending
to your needs, for example he can assign one or more priority
channels, adjust the scan speed (switching time), the resume time
(the time the radio waits before keeping on scanning), set the busy
or vacant channel stop etc. Please contact your administrator/dealer
for further details.
Radio lock
Your HP125/425 has been provided with a security function which
protects it against the misuse by unauthorized people or accidental
activation of commands. You can lock the radio in two ways:
• Full lock: every command is locked.
• Partial lock: only the keypad is locked.
Every time you unlock the radio you will have to enter a 4 digits
security code called PIN (personal identification number).

Selcall and CTCSS/DCS Operation
Reception
During CTCSS/DCS and Selcall operation the radio may be set-up
so that the appropriate CTCSS/DCS and Selcall decoder enables the
speaker. Speaker will remain muted until the correct CTCSS tone,
the correct DCS code and/or the appropriate selective call is received.
In case of unmuted speaker, the message will be heard, the status
LED will glow green and the receive icon will be displayed. Moreover
the strength level of the received signal is displayed

Starting from now, as “address” we mean an ID associated with
an alphanumeric label.
To call an address using the address book:
1) Repeatedly press the MENU key in order to access the command
menu and see on the display the message AddrBook Ok.
4) Hold pressed the
(call) button to call the selected address.
2
If you made a mistake in recalling an address you can abort the
call operation at step 4 by pressing the
(clear) button. Note:
the selected address became the default TX address.

Address book is also useful in reception: in fact when you receive
a selcall ID which is stored in it, your radio will automatically look
for that ID in the address book. If it is stored in it, you will see the
alphanumeric label on the display as well. E.g. if you receive 15
as caller ID, and it is stored in your address book as “Headoffice”,
you will see “Headoffice” in your LCD instead of “15”.

• Recalling the initial letter of the addresses. Press the key which
states the initial letter (e.g. to call Mary press 5, to call John
press 4 etc.) the unit will display the first name of the address
book starting with the selected character (or the next if no names
beginning with the selected character is in the list). If the initial
letter is the 2nd of the 3rd one printed on a key, press respectively
that key two or three times (e.g. to recall the Headoffice press
3 twice). If you have more than one address beginning with the
same initial letter use the
key to scroll down names till you
will reach the proper address.
Stored call (Address book)
This mode allows you to originate a call by using a convenient
alphanumeric address book which has been programmed by your
radio network administrator or dealer with the most used ID associated
to an alphanumeric label, for example:
English
Who-has-called call (Call Queue)
This is a convenient facility which is useful to check who has called
you and eventually call back him/her. First of all please note that your
HP 125-K/HP 425-K has a sort of buffer reception memory which
holds the last 10 received calls:

This buffer memory is displayed similarly to the address book and is
a FIFO (First In First Out) type: it means that the 10th stored address
(the oldest received call) is the first which will be deleted after the
11th received call in order to make room for it.
In the over stated example the 1st received call came from Peter, so
it will be deleted from the call queue as soon as a new call will be
received. All the other addresses (Names with associated IDs) will be
shifted one position down in order to make room for the new address

Sending DTMF patterns
DTMF (Dual Tone Multifunction Frequency) is a standard signalling
system used to dial telephone numbers over a normal PSTN land
line. However in radiocommunications it can be also used to do the
same if your radio channel is connected to a land line via a suitable
device (phone patch). Moreover DTMF is used to send/receive radio
commands or provide signalling similarly to selective calls. For further
details please contact your network administrator. To store dial a
Handsfree transmission (VOX)
VOX (Voice Operated Exchange) is an automatic system which allows
you to automatically switch the transmission in hands free mode just
by speaking in the built-in microphone of an headset (not provided
with the unit). Please ensure that the handset is suitable for your
transceiver as reported in the paragraph “Microphone connection”.
To adjust the VOX sensitivity:
1) Connect the optional headset with built-in microphone to the
microphone connector located on the transceiver’s side.

Information on rechargeable batteries
• When the battery pack is new it doesn’t provide 100% of its
efficiency; it means that it might be discharged earlier. To reach
the full battery life you have to “run-in” the battery with at least
3-4 deep charging/discharging cycles, after that it will reach its
maximum capacity. Please see “Properly charge of battery packs”
for further details.
• Should you properly use the battery pack, you will obtain at least
400 charging/discharging cycles (300 with the optional rapid
charger). The battery duty will progressively reduce after 2/3 of its
life (approx.).
• Rechargeable battery packs lose their charge with the time if left
unused (self discharge); this is normal. A NiMH (Nickel Metal
Hydrate) battery can reduce 10 to 20% of its stored energy in few
days.
Properly charge of battery packs
1) Ensure that the radio is switched off, otherwise switch it off by
holding the
(power) key pressed (release it after the radio is
switched off).
2) Insert the radio into the cradle as explained in the paragraph
“Charging the battery pack”
3) Wait the necessary time to provide a full charge. If the pack isn’t
completely discharged you will need less than 8 hours. Evaluate
the time by using the battery level indicator
and… the common
sense.
22
Care and Maintenance
Erasing memory effect
Memory effect can be easily erased just by applying 3-4 deeper
charge/discharge cycles:
1) Use the battery fitted in the radio and wait till the radio switches
off. Don’t stop when the last battery bar disappears from the
icon, wait till the LCD completely disappears.
2) Wait at least one hour and then try to switch on the radio by
pressing the
button: you will note that some energy has restored
in the battery, because the radio can be switched on.
3) Leave the radio in RX until the radio switches off again.
4) Repeat steps 2) and 3) three times.
5) Fully charge the battery for 9 hours and check the battery duty.
If some memory effect still exist go back to step 1.
2
If the battery duty doesn’t improve after three of the over stated
cycles, it means that your battery pack is faulty or has reached the
end of life (please see “Information on rechargeable batteries”). In
this case please ask your dealer to provide a new battery pack.
Warnings for battery and chargers use
Please use these cautions to avoid damaging battery packs or the
transceiver:
I Before using the battery charger carefully read any related
warning or caution.
I Don’t short battery terminals: this may cause fire, burns or
explosions.
I Never dispose batteries into fire they may explode causing
fire, burns or explosions. Strictly follow any disposal regulation
of your Country.
Care and Maintenance
23
English
I Don’t overcharge the battery: always remember to remove
the radio after the necessary time.
I The battery charger is for indoor use only.
2 When possible, charge the battery when it is fully discharged or,
at least, you have used it for the major part of its duty; otherwise
the battery’s duty could be temporarily reduced. Please see the
paragraph “Memory effect”.
2 Don’t remove the radio before the necessary time, otherwise the
battery’s duty could be temporarily reduced. Please see the
paragraph “Memory effect”.
Memory effect
The supplied NiMH (Nickel Metal Hydrate) battery pack is made with
a more advanced technology than normal NiCd (Nickel Cadmium)
battery. For this reason it is virtually free of what is called “memory
effect”, which affects NiCd batteries. Memory effect is a temporary
capacity reduction which reduces the battery duty. Memory effect
may occur just if you regularly charge the battery when you haven’t
discharged it at least at 50-70%. Memory effect can be easily avoided
by following these simple rules:
• When possible charge battery packs only when they are completely
discharged, i.e. when the battery icon has no bars inside.
• Don’t remove the battery from the charger before the necessary
time to provide a full charge.
• Provide at least two deep charge/discharge cycles per month.
• The best way to avoid memory effect is to use two battery packs
and alternate their use with the radio. This will allow you to keep
on your transceiver’s operation by replacing the battery pack just
when it’s fully discharged and use the spare (charged) one. At the
end of your working day you will charge the discharged pack for
8 hours.
English
I Use only genuine batteries and chargers. The use of non
genuine accessories may cause burns, fire or explosions;
making serious damages to the radio/battery or serious injuries
to people.
I Battery chargers are for indoor use only.
I Be certain that your power source matches the rating listed
for the supplied battery charger (AC Adaptor). If you are not
sure, check with your dealer or with your local power company.
I To avoid damaging the power cable of the battery charger,
do not put anything on it or place it where it will be walked
on. Insert the plug in socket provided with earth connection.
I Avoid strong shocks. Don’t use the charger if it received a
strong shock, has fallen down or it appears damaged;
immediately contact an authorized service station.
I Never try to disassemble or service the charger by yourself.
Always contact your local dealer for assistance.
I To reduce the risk of electric shocks disconnect the plug
before providing any cleaning or maintenance. Grasp the plug
(not the cable) to remove the plug from the socket. The use
of non suitable extension can cause fire or electric shocks.
I Don’t expose batteries directly to temperatures below -20°C
or greater than 35°C during their use and don’t charge them
outside the range of +5 to +55°C.
Radio maintenance
Cleaning battery packs
Wipe the battery contacts with a clean and lint free cloth to remove
dirt, grease or any other material which may prevent a good electrical
contact. If contacts are very dirty you can also wipe them using a
soft pencil rubber (not hard erasers for ink!). If you feel that battery
contacts aren’t still working properly, please contact your authorized
dealer.
