Chronomatic-309 AM/FM Stereo Clock Radio with Cassette Recorder (120-1609) Preparation Faxback Doc. # 18569 CONNECTING POWER Plug the Chronomatic-309's power cord into a standard AC outlet. INSTALLING THE BACKUP BATTERY To keep the clock running in the event of an AC power failure, install a 9-volt backup battery (not supplied). We recommend an alkaline battery, such as Radio Shack Cat. No. 23-553. A fresh battery powers the clock for up to 8 hours, and sounds the alarm for up to 10 minutes if AC power fails. NOTES: Before you install the backup battery, plug in the AC power cord to prevent unnecessary drain on the battery. Replace the battery when the BATTERY SENTINEL indicator on the right side of the display lights. If the BATTERY SENTINEL indicator lights after a power failure, press ALARM 2 SET to turn it off. If the indicator lights again, or if it comes back on the next day, replace the backup battery. If the display flashes after an AC power failure, replace the battery and reset the clock. 1. While pressing and holding the battery compartment cover's latch, pull up on the battery compartment cover to remove it. 2. Snap the battery into the terminals and place it in the compartment. CAUTION: Use only a fresh battery of the required size and type. 3. Replace the cover. ADJUSTING THE DISPLAY Set DIMMER HI/LO on the back of the Chronomatic-309 to HI (high) or LO (low), depending on the amount of light in the room. CONNECTING AN EXTERNAL FM ANTENNA You can connect an external FM antenna (not supplied) to the Chronomatic- 309 for improved FM reception. Your local Radio Shack store sells a complete line of external antennas. Follow these steps to connect an external FM antenna to the Chronomatic- 309. 1. Use a Phillips screwdriver to loosen both screws on the external antenna terminals. 2. Remove the internal FM antenna's spade lug from the external antenna terminal. 3. Slide both of the external antenna's spade lugs underneath the screw heads. 4. Retighten the screws. (JC 11/21/95)
