On the backside of the receiver is the battery door. Lift the tab and turn counter-clockwise to release the door. Insert the battery gently into the housing with the contact tabs facing down. Replace the door and turn the tab clock-wise to secure the door shut.

Connect the two-piece power cord and insert the LEMO connector end into the power port on the Asteri device.
*Be sure to line up the RED DOT on the cable with the slot on the bottom of the housing.

This is a "pin" connection, so be careful not to force the connection. If lined up properly, the connection will be easy.

Plug the AC adaptor into a power source and you will notice the battery LED's begin to pulse.
After the battery has achieved a certain level of power, that LED will stay lit.
