PREPARATION
CONNECTING POWER
Plug the clock radio’s power cord into a standard AC outlet.
The display flashes.
Note: The power cord’s plug is polarized (one side is larger
than the other). If it does not fit, turn it over. Do not force it.
INSTALLING THE BACKUP 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.
5
Notes:
• To prevent unnecessary drain on the backup battery,
plug in the AC power cord before you install the battery.
• The clock’s display does not light while operating from
battery backup power, but the clock keeps time for up
to 8 hours.
• If the display flashes after a power failure, the battery is
too low to run the clock. Replace the b attery and reset
the clock.
1. Press the latch on the battery
compartment cover and slide
the cover in the direction of
the arrow and remove it.
2. Snap the battery into the bat tery terminals. Then put the
battery in the compartment.

3. Replace the cover.
The BATTERY SENTINEL lights automatically if the battery
needs to be replaced or is not installed.
USING EARPHONES
To liste n in privacy, turn
plug a monaural earphone with a
PHONE
jack. Your local Radio Shack store has a c omplete
VOLUME
to its lowest setting and
1
/8-inch plug into t he
EAR-
line of earphones.
Listening Safely
To protect your hearing, follow these guidelin es when you
use an earphone.
7
• Set the volume to the lowest setting before you begin
listening. After you begin listening, adjust the volume to
a comfortable level.
• Do not listen at extremely high volume levels. Extended
high volume listening can lead to permanent hearing
loss.
• Once you set the volume, do not increase it. Over time,
your ears adapt to the volume level, so a volume level
that does not cause discomfort might still damage your
hearing.
