Recharging and Replacing the Battery
To replace the battery:
1. Turn off the unit (if the AC adapter is plugged in, you may replace the
battery while unit is on).
2. Remove the battery compartment cover, located at the back of the
unit.
3. Pull out the old b battery using your fingers. Flipping the unit, battery-
side down, will ease removal. Do not use tools
in order to prevent damage to the battery envelope. Pull out the
electrical connector. Put aside the old battery.
4. Remove the new battery from its package (keep the package for future
use). Connect the electrical connector, ensuring that the pins are
correctly aligned. Place the new battery into the unit.
5. Inspect the inside rib around the unit battery compartment to make
sure it is free from any debris. Remove any debris using a dry cloth.
Replace the battery compartment cover.
