Inserting and Removing Battery Packs
To insert a battery pack, place the end of the battery without the locking tab into the bottom of the charging
pocket and snap the battery into place with a hinging motion. The Status LED for that particular slot lights
orange when the battery has been properly inserted. To remove a battery pack, push the locking tab down
and pull the battery out from the charging slot with a hinging motion.

2. Connect the power cable to the power adapter.
3. Connect the power cable to the supply connector on the back of the device.
4. Press the power switch to the ON position.
