Chronomatic-305 AM/FM Cassette Clock Radio (120-1608) Installation Faxback Doc. # 18243 CONNECTING TO AC POWER Plug the power cord into a standard AC outlet. The display flashes. NOTE: The plug is polarized (one blade is larger than the other) and fits one way. Do not force it. If the plug does not fit, turn it over and try again. INSTALLING A 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. NOTE: To prevent unnecessary drain on the back-up battery, install the battery after you plug in the AC power cord. Follow these steps to install a back-up battery. 1. Slide the battery compartment cover (located on the bottom of the clock radio) in the direction of the arrow, and remove the cover. 2. Snap the battery's terminals onto the terminals in the compartment. 3. Replace the cover. NOTES: Replace the battery when the BATTERY SENTINEL indicator lights. 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. The display does not light when the Chronomatic-305 is operating from battery back-up power. The alarm time occurs while the Chronomatic-305 is operating from battery back-up power, the alarm buzzer sounds or the radio plays for up to 10 minutes. If the Chronomatic-305 is set to play a cassette tape at the alarm time, the buzzer sounds instead. (CS 11/21/95)
