Introduction
Congratulat ions. HP125 is an advanced PMR (Professional Mobile Radio). It s r ugged design allows it to be
your reliable partner even during hard working days. It s large LCD as well as user f riendly controls make
the HP125 easy t o use.
HP125 is a real system radio, supporting CTCSS/DCS, 5 t one signaling systems (encoder/decoder up to
28 + 28 tones), FFSK, DTMF and trunking system property. Selcall mode supports also many f acilities,
such as an alphanumer ic address book, a call queue function as w ell as a status message table. Y ou can
also use FFSK to send/receive short text messages which you can enter via t he alphanumeric keypad. The
way your radio operat es may be upgraded and may differ f r om w hat is described here.
To extend the flexibility, the radio is provided with VOX function, which allows you to switch on the
transmitter just by talking us ing an optional headset f or f ull hands free operation.

Fitting/removing the antenna
To fit the antenna:
1) Locate the ant enna terminal ( t hread MX connector) on transceiver’s top.
2) Hold the transceiver w it h one hand and the base ( the thicker par t ) of the ant enna with the other one.
3) Attach the included f lexible antenna to t he antenna terminal by tur ning the ant enna clockwise until it is
firmly locked. Don’t overtighten the antenna!
To remove the antenna revers e the previous step.

Leave the antenna attached on the radio. You can not communicate without it. Moreover,
transmitting without the antenna may damage the TX f inal stage. For the same reason us e only the
supplied antenna.

Basic Operation s
This section describes how the standard operations work. Programming can change standard operation.
Functions of the radio can be modified via an IBM compatible PC. For this reason the way your radio
operates may be upgraded and may slightly differ fr om what is described here.
!
IMPORTANT: Due to the full programmability of the radio, certain menu commands could be
unavail able. E.g. i f your radi o has not been programmed f or selective cal l operations, the rel ated
menu commands won’t be recalled. In case of doubts please contact your dealer/radio network
administrator for f ur ther detai l s .
Switching the radio ON/OFF
To switch the radio on:
1) Hold the (power) button until the radio is switched on: the LCD will start an autotest showing in
sequence:
• A welcome message (if previously pr ogr ammed – it is usually your company name or your per s onal
sta tion identif ic a tion). At the sa me time all the LCD ic o ns will be show n fo r one seco nd as LCD test.
• The firmware release number (FW Rev.).

Stored call (Address book)
This mode allows y ou to originat e a call by using a convenient alphanumeric address book which has been

alphanumeric label, for example:

life you must “run-in” the battery with at least 3-4 deep charging/dischar ging cycles, after that it will
reach its maximum capacity. Please see “Proper charging of battery packs” f or f urther details.

Memory effect
The supplied NiMH (Nickel Metal Hydride) battery pack is made with a more advanced technology than

which af fects NiCd batteries. Memory ef fect is a temporar y capacity reduction which r educes t he batter y

least at 50- 70%. Memory eff ect c an be easily avoided by following these simple rules:
• When possible charge battery packs only when they are completely discharged, i.e. when the
batter y icon has no bar s inside.
• Don’t r emove the battery f r om the charger before the necessar y t ime to pr ovide a full charge.
• Provide at least two deep charge/discharge cycles per mont h.

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 until the radio switches off. Do not stop w hen the last battery

2) Wait at least one hour and then try t o turn t he r adio on by pressing the butt on: yo u w ill note t ha t
