Radio Shack TAD-1007 owner manual Connecting to Power, Installing Backup Battery

CONNECTING TO POWER

Insert the supplied adapter’s barrel plug into the AC 9V jack on the back of the TAD. Then plug the AC adapter’s other end into a standard AC outlet.

Caution: Only use an adapter that sup- plies 9 volts AC, delivers at least 780 milliamps, and has a plug which properly fits the TAD’s AC 9V jack. The supplied AC adapter meets these specifications. Using an adapter that does not meet these specifications might damage the TAD or the adapter.

When you first connect power, _ _ flashes on the display while the TAD au- tomatically runs a self-test. You cannot operate the TAD during this test. When the test is complete, the TAD beeps once. Lo and 00 alternately flash on the display until you install the backup bat- tery.

INSTALLING THE

BACKUP BATTERY

During an AC power failure, a 9-volt bat- tery (such as Cat. No. 23-553, not sup- plied) provides backup power so the TAD can maintain the correct time and memory information. However, the TAD cannot answer incoming calls and record messages without AC power.

Follow these steps to install the battery.

1.Slide the battery compartment cover (located on the bottom of the TAD) in the direction of the arrow and lift it off.
