powered by the AC adapter. The constant
trickle charge maintains the battery level to
eliminate the battery self-discharge effect.
The charge-in-use function also charges the
battery pack.

devices are connected to these ports. You can
do this through the Setup Utility. See section
5.3.3.

The recommended storage temperature for
battery packs ranges from 10 to 30 degrees C.
The higher the storage temperature, the faster
the battery pack self-discharges.

times when used as directed. Excess
recharging decreases battery life.
q Take care of your battery pack and AC
adapter. See the notices section found in the
front part of the user’s guide.
