AM/FM LED Clock Radio With Automatic Timer and Nightlight (120-1611) Preparation Faxback Doc. # 18063 Connecting to AC Power Plug the clock's power cord into a standard AC outlet. The display flashes when you first plug in the clock or when the power is interrupted and the back-up battery is weak or missing. When you set the time, the display stops flashing. Installing the Backup Battery To keep the clock running during an AC power failure, install a 9-volt alkaline battery. We recommend Radio Shack Cat. no. 23-553. NOTES: To prevent unnecessary battery drain, install the battery after you connect the radio to AC power. If the BATTERY SENTINEL indicator lights after an AC power failure, or when you press SNOOZE, the battery is too low to power the clock. Replace the battery and set the time. The back-up battery only powers the clock (not the light). Follow these steps to install the back-up battery. 1. Press the tab and remove the battery compartment cover. 2. Snap the battery onto the terminals and place it inside the battery compartment. 3. Replace the cover. (EB 11/22/95)
