Chronomatic-304 (120-1604) Preparation Faxback Doc. # 9497 CONNECTING TO AC POWER Plug the clock radio's AC power cord into a standard AC outlet. 12:00 flashes on the display until you set the clock (see "Setting the Clock"). INSTALLING THE BACK-UP BATTERY To keep the clock running during an AC power failure, install a 9-volt battery. For the longest life, we recommend an alkaline battery, such as Radio Shack Cat. 23-553. Notes: To prevent unnecessary drain on the back-up battery, install the battery after you plug in the AC power cord. The battery sentinel indicator lights if battery power is low or the battery is not installed. Install a fresh battery when the indicator turns on. The clock's display does not light while the clock is using back- up battery power, but the clock and alarm operate for up to 8 hours. A prolonged power failure can drain the battery. If the display flashes when power is stored after an AC power failure, replace the battery and reset the clock. Follow these steps to install the back-up battery. 1. Press the tab and lift off the battery compartment cover. 2. Snap the battery onto the battery contacts. 3. Replace the cover. (LB/all-01/18/95)
