30 Allegro DOS Owner’s Manual
Slide the latches downward until they cannot slide any further to
securely latch the battery door closed.
Do not turn on the Allegro yet.
Plug the AC wall charger that came with the Allegro into the wall
socket.
The small green light on the wall adapter turns on when it is
plugged into the wall.
Remove the rubber protector from the Allegro’s external power
input jack.
Plug the power connector end of the wall charger into the
Allegro.
Charge the battery pack at room temperate until the LED charge
light (lightning bolt) on the Allegro turns off. This can take three
to fi ve hours the fi rst time you charge the battery.
By initially charging the batteries this way, you become familiar with
the Allegro’s battery gauging feature and how the battery status
LEDs work. This recommendation is made even if you eventually
plan to use an external battery charger to charge the battery pack or
if you are going to use the optional alkaline battery holder.
