Chronomatic-290 (120-1590A) Preparation Faxback Doc. # 15171 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 an alkaline battery such as Radio Shack Cat. No. 23-553 for the best performance. NOTES: To prevent unnecessary drain in 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 operates 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 display flashes after a power failure or at least every 6 months. 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. (LB/all-05/08/95)
