INSTALLING THE BACKUP BATTERY

The TAD requires AC power to operate. If AC power fails, or you unplug the TAD, a 9-volt battery (not supplied) provides backup power so the TAD can maintain the correct time and memory information. For the best performance and longest life, we recommend a RadioShack alkaline battery.

Caution: Use only a fresh battery of the required size and rec- ommended type.

Follow these steps to install the battery.

1.Use a flat-blade screwdriver to unlatch the battery compart- ment cover, then lift off the cover.

2.Insert the battery pack into the battery compartment as indicated by the polarity symbols (+ and –) marked inside.

3.Replace the cover and press down on the latch to secure it.

When /R and the two-digit number of calls in memory alternate- ly flash on the display, replace the battery. When you replace the battery, be sure the TAD is connected to AC power so you do not lose any stored information.

Warning: Dispose of old batteries promptly and properly. Do not burn or bury them.

Caution: Always remove old or weak batteries. Batteries can leak chemicals that can destroy electronic parts.
