ground wire in the lower left corner of the processor
board.
3. Locate the battery socket.
4. Carefully insert a small screw driver between the bat-
tery socket and battery. Gently apply upwards pressure
prying the battery out of the socket.

entation as the old battery, the side with writing facing
out.
6. Carefully apply pressure down to seat the new battery.
7. Power up the panel and wait until the Quantum HD ap-
plication has loaded.
