4.4 Recharging the battery pack
The fast double desktop battery-charger enables to recharge the
battery pack without removing it from the radio or to recharge the
battery pack separately. The charger is able to recharge both Li-Ion
and Ni-MH battery pack.
2
At the end of the recharge operation, it is possible to leave the
radio/battery pack in the charger, because the latter has a special
protection that prevents the battery pack from being damaged by
overvoltages.

Battery packs tend to loose their charge if they are not used
(automatic discharge). This condition is perfectly normal. All
models of battery packs tend to loose 10 - 20% of their power
after a few days.
I
If the battery pack is new, it is necessary to fully recharge
it before using it. Then, it is sufficient to follow the
recommendations given in paragraph 4.4.a.
I
Always use the battery-charger with the above-described
models of battery packs. Do not attempt to use the battery-
charger to recharge other types of batteries (and specifically
alkaline batteries), as this operation could cause explosions
and personal injuries.
I
Always keep the battery-charger compartments clean.
