4.2.b Removal
1) follow steps 1 and 2 of par 4.2.a;
2) Remove the batteries from the device;
3) Follow steps 4 and 5 of par 4.2.a.

4.3 Recharging batteries

Batteries can be recharged without taking them out of the transceiver (but the device must be
turned off); Batteries take 12 -13 hours to fully recharge (rechargeable batteries1700mA/h).
To recharge batteries:
1. Carefully lift the rubber protection of the socket MIC/CHG
2. Insert the jack of the battery charger (sold separately) in the socket MIC/CHG of the radio,
then connect the battery charger to a mains power socket. Charging will begin
3. When charging is complete pull out the charger's jack from the radio and detach it from the
mains. Replace the rubber protection mentioned in step 1.
!
Do not overcharge the batteries! When these are fully charged the charging process
does not stop automatically. Do not forget therefore, to remove the charger from the
transceiver as soon as the batteries are charged.
!
Do not try to charge alkaline batteries or non rechargeable batteries. Make sure that
when you connect the charger only rechargeable batteries NI-MH should be contained
in the batteries compartment! It is very dangerous attempting to recharge other types of
batteries (for example alkaline or manganese batteries). Batteries which are not suitable
to be recharged may leak, explode or even burn and cause damage!
!
Using a different battery charger other than the one specified can cause damage to your
device or may even cause explosions and personal injuries.
!
Do not throw batteries into fire or place them near heat as this may cause explosions
or personal injuries. Dispose of the batteries according to procedures set out by local
regulations.
!
Do not mix old and new batteries or batteries of different types or batteries which have
been used in different manners. Every battery set which is being used must always be
composed of the same elements.

4.4 Memory effect of rechargeable batteries

Rechargeable NiMH (Nickel-Metal-Hydrate) batteries are affected by what is known as the
"memory effect". This phenomenon is associated with a drastic reduction of battery autonomy
and is triggered if the batteries are regularly charged before being fully discharged and/or are not
completely recharged. To avoid the memory effect:
• When possible, recharge the batteries only when they are completely discharged (until the
device turns itself off during normal use)
• Do not disconnect the battery charger before the time indicated for a full battery charge.
• Discharge and recharge your batteries completely at least twice a month. In any case, the best
solution for avoiding the memory effect is to use in turn two battery sets: one in use, and the
other as a spare set.
The memory effect can be easily eliminated by completely discharging/charging the batteries
3 or 4 times.
The memory effect should not be confused with the normal battery life, which is 400 cycles of
charge/discharge on average. It is completely normal for operating duty to decrease when the
batteries have reached the end of their life; at this point, you will need to substitute the battery
set.
