Chronosette-276 (120-1584) Preparation Faxback Doc. # 3768 CONNECTING TO AC POWER Plug the power cord into a standard AC outlet. INSTALLING THE BACK-UP BATTERY To keep the clock running in the event of an AC power failure, install a 9-volt battery. We recommend Radio Shack's Enercell battery Cat. No. 23-583. A fresh battery can keep the clock running for up to 8 hours and sound the alarm for up to 10 minutes if AC power fails. Notes: An extra-life battery works best with the battery sentinel feature. To prevent unnecessary drain on the backup battery, install the battery after you plug in the AC power cord. If the BATTERY SENTINEL indicator lights, change the battery. If the display flashes after an AC power failure, the battery is too low to accurately run the clock. Replace the battery and reset the clock. Follow these steps to install the back-up battery. 1. Slide the battery compartment cover in the direction of the arrow and remove it. 2. Place the battery connector over the battery contacts. 3. Replace the battery compartment cover. The battery is automatically tested once each day by the built-in sentinel circuit. If the BATTERY SENTINEL indicator lights, replace the battery. The BATTERY SENTINEL indicator might light after a power failure. If this happens, press ALARM SET 2 to turn it off. If the indicator lights again, or if it comes back on the next day, replace the battery. CONNECTING AN EXTERNAL FM ANTENNA You can connect an external FM antenna (not included) to the Chronosette-276 for improved FM reception. Your local Radio Shack store has a complete line of external antennas to choose from. To connect an external FM antenna to the Chronosette-276, slightly loosen the 2 screw terminals and slide the antenna's spade lugs underneath the screw heads. Then, tighten the screws.
