INSTALLING A BACKUP BATTERY
Notes:
•If the AC power fails or you unplug the TAD, a 9V backup battery (not supplied) saves the messages, time and day settings, and CBT and remote operation security codes. For the best performance and long- est life, we recommend you use a RadioShack alkaline battery.
•If the AC power fails or you unplug the TAD, the TAD can receive Caller ID records. However, the TAD can- not operate on backup battery power alone.
Caution: Always use a fresh battery of the required size and recommend type.
1.Use a Phillips screwdriver to remove the screw on the battery compart- ment cover, then remove the cover.
3.Replace the cover and secure it with the screw.
Replace the battery when 
ap- pears.
Warning: Dispose of the old battery promptly and properly. Do not burn or bury it.
Cautions:
•Before you replace the battery, be sure the TAD is properly connected to AC power. Otherwise, you might lose any stored information.
•Disconnect the telephone line cord before replacing the battery to reduce the risk of fire or injury. Use only a 9 Volt alkaline or super heavy duty battery.
•Always remove old an or weak bat- tery. A battery can leak chemicals that can destroy electronic parts.
