CONNECTING TO AC POWER
Plug the power cord into a standard AC outlet.
INSTALLING THE BACK-UP BATTERY
To keep the clock running in the event of an AC power failure,
install a 9-volt battery. We recommend Radio Shack's Enercell battery
Cat. No. 23-583. A fresh battery can keep the clock running for up to 8
hours and sound the alarm for up to 10 minutes if AC power fails.
Notes: An extra-life battery works best with the battery sentinel
feature.
To prevent unnecessary drain on the backup battery, install the
battery after you plug in the AC power cord.
If the BATTERY SENTINEL indicator lights, change the battery.
If the display flashes after an AC power failure, the battery is
too low to accurately run the clock. Replace the battery and
reset the clock.
Follow these steps to install the back-up battery.
1. Slide the battery compartment cover in the direction of the arrow
and remove it.
2. Place the battery connector over the battery contacts.
3. Replace the battery compartment cover.
The battery is automatically tested once each day by the built-in
sentinel circuit.
If the BATTERY SENTINEL indicator lights, replace the battery.
The BATTERY SENTINEL indicator might light after a power failure.
If this happens, press ALARM SET 2 to turn it off. If the indicator
lights again, or if it comes back on the next day, replace the
battery.
