INSTALLING A BACKUP BATTERY
If AC power fails or you unplug the TAD, a 9V backup battery (not supplied) saves the message groups, message counts, and the settings for the day, time, and security code. We recommend you use an alkaline battery, such as Ra- dioShack Cat. No.
Caution: Always use a fresh battery of the required size and recommended type.
1.Use a Phillips screwdriver to remove the screw on the battery compart- ment cover, then remove the cover.
2.Snap the battery’s contacts firmly to the battery connector and place the battery into the compartment.
3.Replace the cover and secure it with the screw.
Replace the battery when Lo appears.
Cautions:
•Before you replace the battery, be sure the TAD is properly connected to AC power. Otherwise, you might lose any stored information.
•Always remove old or weak batter- ies. Batteries can leak chemicals that can destroy electronic parts.
•Dispose of the old battery promptly and properly. Do not burn or bury it.
SETTING THE DAY AND TIME
To avoid losing the day and time settings if AC power fails, we recommend you in- stall a backup battery before you set the day and time (see “Installing a Backup Battery”).
Follow these steps so the TAD can record the correct day and time each message and memo is recorded.
Note: If you do not complete each step within 8 seconds, the TAD sounds four beeps and exits setup. Start again at Step 1.
