AM/FM Clock Radio with 1.8-Inch Display

PREPARATION  
Follow these steps to install the back-up  
battery once you have connected the  
clock to AC power.  
CONNECTING POWER  
To operate the clock, plug the power  
cord into a standard AC outlet. The dis-  
play flashes 12:00 until you set the  
time (see “Setting the Time” on Page 4).  
Caution: The clock radio’s AC power  
cord is equipped with a polarized plug to  
prevent electric shock. One blade on the  
cord’s plug is wider than the other and  
the plug only fits an outlet one way. if  
you can not easily insert the plug, turn it  
over and try again. Do not force it.  
INSTALLING A BACK-UP  
BATTERY  
1. Press the battery compartment  
cover’s tab in the direction of the  
arrow, then lift off the cover to  
remove it.  
If AC power fails, the clock radio has a  
Battery Sentinel back-up power system  
that continues to operate the clock for  
up to 8 hours with the display turned off  
to conserve power. This lets the alarm  
sound for at least 10 minutes at the set  
time, even if AC power fails.  
2. Snap the battery into the connector  
in the battery compartment and  
place the battery in the compart-  
ment. The BATTERY SENTINEL  
indicator turns off.  
3. Replace the cover.  
The BATTERY SENTINEL indicator  
lights if there is either no battery in-  
stalled or the installed battery requires  
replacement.  
Caution: Always remove an old or  
weak battery. Batteries can leak  
chemicals that can destroy elec-  
tronic parts.  
Your clock radio requires a 9-volt battery  
(not supplied) for its back-up power sys-  
tem. For the best performance and long-  
est life, we recommend a RadioShack  
alkaline battery.  
Warning: Dispose of old batteries  
promptly and properly. Do not bury  
or burn them.  
Caution: Use only a fresh battery of the  
required size and recommended type.

THE FCC WANTS YOU TO  
KNOW  
To enjoy your AM/FM Clock Radio for a  
long time:  
Your clock radio might cause TV or ra-  
dio interference even when it is operat-  
ing properly. To determine whether your  
clock radio is causing the interference,  
turn off your clock radio. If the interfer-  
ence goes away, your clock radio is  
causing the interference. Try to elimi-  
nate the interference by:  
• Keep the clock radio dry. If it gets  
wet, wipe it dry immediately.  
• Use and store the clock radio only in  
normal temperature environments.  
• Handle the clock radio gently and  
carefully. Don’t drop it.  
• moving your clock radio away from  
the TV or radio  
• Keep the clock radio away from dust  
and dirt.  
• connecting your clock radio to an  
outlet that is on a different electrical  
circuit from the TV or radio  
• Wipe the clock radio with a damp  
cloth occasionally to keep it looking  
new.  
• contacting your local RadioShack  
store for help  
Modifying or tampering with the clock ra-  
dio’s internal components can cause a  
malfunction and invalidate its warranty.  
If your clock radio is not performing as it  
should, take it to your local RadioShack  
store for assistance.
