PREPARATION
CONNECTING POWER
Plug the Chronomatic-278’s power
cord into a standard AC outlet. The display flashes when the radio is first
plugged in or if the power is interrupted
and the backup battery is missing or
weak.
INSTALLING THE
BACKUP BATTERY
To keep the clock running in the event
of a 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 power fails.
• If the display flashes after a power
failure, replace the battery and
reset the clock.
1. To remove the battery compartment cover, press and hold the
tab in the direction of the arrow
then lift off the cover.
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.
Notes:
• Before you install the backup battery, plug in the power cord to prevent unnecessary drain on the
battery.
• Replace the battery when BATTERY SENTINEL on the right side
of the display lights.

ADJUSTING THE

CARE AND MAINTENANCE
Your clock radio is an example of superior design and craftsmanship. The following
suggestions will help you care for your clock radio so you can enjoy it for years.
Keep the clock radio dry. If it gets wet, wipe it dry immediately. Liquids
might contain minerals that can corrode the electronic circuits.
Handle the clock radio gently and carefully. Dropping it can damage
circuit boards and cases and can cause the clock radio to work improperly.
Use and store the clock radio only in normal temperature environments. Temperature extremes can shorten the life of electronic devices and distort or melt plastic parts.
Keep the clock radio away from dust and dirt, which can cause premature wear of parts.
CLEANER
Wipe the clock radio with a damp cloth occasionally to keep it looking
new. Do not use harsh chemicals, cleaning solvents, or strong detergents to clean the clock radio.
Modifying or tampering with the clock radio’s internal components can cause a malfunction and might invalidate your clock radio’s warranty and void your FCC authorization to use it. If your clock radio is not performing as it should, take it to your local
Radio Shack store for assistance.
