CONNECTING TO AC POWER
Plug the clock radio's power cord into a standard AC outlet. The display
flashes.
INSTALLING THE BACK-UP BATTERY
To keep the clock running during an AC power failure, install a
9-volt battery. We recommend Radio Shack's Enercell Extra Life battery
(Cat. No. 23-583) for best performance.
Notes: To prevent unnecessary drain on the back-up battery, install the
battery after you plug in the AC power cord.
The clock’s display does not light while operating from battery
back-up power, but the clock and alarm operate for up to 8 hours.
A prolonged power failure can drain the battery. If the display
flashes after an AC power failure, the battery is too low to run
the clock. Replace the battery and reset the clock.
Replace the battery when the BATTERY SENTINEL indicator lights.
Follow these steps to install the back-up battery.
1. Press the tab and lift off the battery compartment cover on the
bottom of the clock/radio.
2. Snap the battery onto the battery contacts.
3. Replace the cover.
TESTING THE BATTERY
The BATTERY SENTINEL indicator lights automatically if battery power is
low, or the battery is not installed.
