Chronomatic-302 (120-1600) Preparation Faxback Doc. # 3389 CONNECTING POWER Plug the clock's power cord into a standard AC outlet. The display flashes when you plug in the clock, or when the power is interrupted and there is no back-up battery installed. When you set the time, the display stops flashing. See "Setting the Time." INSTALLING A BACK-UP BATTERY You can install a 9-volt battery for back-up power. We recommend an alkaline battery, such as Radio Shack Cat. No. 23-553. The clock runs for about 12 hours during a power failure if a fresh back-up battery is installed, and the alarm sounds at the preset time. Note: To prevent unnecessary battery drain, be sure to connect the clock to an AC outlet before you install the battery. Follow these steps to install the back-up battery. 1. Open the battery compartment cover. 2. Snap the battery into the terminals and insert it into the compartment. 3. Close the cover. Note: If the display flashes when power is restored after a power failure, replace the battery and reset the clock. If the BATTERY SENTINEL indicator lights, the back-up battery is dead, not installed, or is too weak to run the clock/radio. SETTING THE TIME 1. Press and hold down TIME on top of the clock. 2. While holding down TIME, repeatedly press (or press and hold down) HOUR until the correct hour appears. Note: The PM indicator on the display lights when you set the time to a PM hour. 3. While holding down TIME, repeatedly press (or press and hold down) MINUTE until the correct minute appears. 4. Release TIME when the correct time appears. (br/all-12/02/94)
