recommend, when possible, to use the Low pmver setting. This will increase the battery life and will
reduce the risk of interference with other stations not in your radio network which may be sharing the
same channel with you.
1) To change the channel‘s Power Output level from high (2 Watts) to Law (1 Watt). or vice versa, Press
and Hold “FUNC” key tor about 2 seamds, A small "LOW" will appear in the lower left corner of the
display to initiate “Low Power". High Power has no indicator.
E? It the battery icon is "blinking" (Low Battery indication), the Unit will automatically switch to Low
Power when transmitting In order to help prolong the Battery’s operational life. In this case, two
short beeps will be heard when you press the "P'IT" key before the radio transmits.

- When possible charge battery packs only when they are completely discharged, t.e. when the
battery icon has no bars inside.
- Do not remove the battery from the charger before the necessary time to provrde 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 using your transceiver by replacing the battery pack just when it
is fully discharged. At the end of your working day you will charge the discharged pack tor 8
hours.
Erasing memory effect
Memory effect can be easily erased just by applying 34 deeper charge/discharge cycles:
1) Use the battery fitted in the radio and wail till the radio swrtches off,
7) Wait at least one hour and then try to switch on the radio: you will note that some energy has restored
in the battery, because the radio can be switched on.
8) Leave the radio in RX until the radio switches ott again.
9) Repeat steps 2) and 3) three times
10) Fully charge the battery tor 9 hours and check the battery duty. If some memory effect still exist go
back to step 1
e? If the battery duty doesn’t improve alter three of the over stated cycles, it means that your battery
pack is faulty or has reached the end of liIe (please see “Information on rechargeable batteries“). In
this case please ask your dealer to provrde a new battery pack.
Warnings tor battery and chargers use

Care and Maintenance
Battery Packs
lnlormation on rechargeable batteries
- When the battery pack is new it will not provide 100% of its efficiency. To reach the full battery
run time you have to “mn—in" the battery with at Im 3-4 deep charging/discharging cycles. After
that it will reach its maximum capacity. Please see “Proper charging of battery packs" for further
details.
0 When you properly use the battery pack. you will obtain about 400 charge/discharge cycles (300
with the optimal rapid charger). The battery “run time“ will progressively reduce after 2/3 of its life
(approx).
0 Rechargeable battery packs lose their charge with time if left unused (self-discharge), this is
normal, A NiMH (Nickel Metal Hydrate} battery can reduce to to 20% of its stored energy in few
clays.
Proper charging of battery packs
1) Ensure that the radio is switched off.
5) Insert the radio into the cradle as explained in the paragraph “Charging the battery pack'
6) Wait the necessary time to provide a full charge. it the pack isn't completely discharged you will need
less than 8 hours.
6 Do not overcharge the battery: always remember to remove the radio aftertha necessary time.
t? The battery charger is for indoor use only.
Q When possible, charge the battery only when it is fully drscharged or, at least, you have used it for
the major part of the day, otherwise the battery's "run time” could be tsmpomrily reduced. Please
see the paragraph “Memory effect".
Q Do not remove the radio before the necessary time, otherwise the battery's ”mn time" could be
temporarily reduced Please see the paragraph Memory effect".
Memory effect
The supplied NiMH (Nickel Metal Hydride) battery pack |s 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 elfect can be easily avoided by following these simple rules.
