pack for 16 hours without interruption with the Adaptor.

Place the ATLANTIS 250 in

1

the Cradle.
Make sure your radio is OFF.

Plug one end of the AC adaptor into the wall

2

outlet and the other end into the Adaptor jack
on the back of the ATLANTIS 250.

Charge the battery for 16 hours.

3

• The charger will not overcharge the battery pack. After 16 hours
without interruption, charging is completed.

• Be sure to replace the rubber cap after charging in order to

secure the splashproof seal.

• The radio will not charge the battery while on and receiving
incoming voice traffic.

• When you mount the Cradle on your boat, use the DC adaptor
instead.

• The jack is for charging only. If the battery level is low, the radio
needs to be charged before use.
