Problem Suggestion
Scanner receives stations poorly 
or not at all.• Check the antenna (indoor
or outdoor). See “Connect-
ing the Flexible Antenna” on
Page 9 and “Connecting a
Mobile or Base-Station
Antenna” on Page 35.
• Signals may be blocked
from being received by the
scanner due to metal
frames or material in the
building. Change the scan-
ner ’s location and try again.
Scanner’s keys or display work 
poorly or not at all.• The scanner’s keys are
locked. Unlock the scan-
ner’s keys. See “Using the
Keylock” on Page 32.
• Reset the scanner. See
“Resetting the Scanner” on

that have an unclear transmis-
sion.You might have tuned to a birdie
frequency. Avoid programming
frequencies listed under “Birdie

CARE AND MAINTENANCE
Your Radio Shack PRO-63 100-Channel Portable Event Scanner
is an example of superior design and craftsmanship. The following
suggestions will help you care for your scanner so you can enjoy
it for years.
Keep the scanner dry. If it gets wet, wipe it dry im-
mediately. Liquids can contain minerals that can
corrode the electronic circuits.
Handle the scanner gently and carefully. Drop-
ping it can damage circuit boards and cases, and
can cause the scanner to work improperly.
Use and store the scanner only in normal temper-
ature environments. Temperature extremes can
shorten the life of electronic devices and distort or
melt plastic parts.
Keep the scanner away from dust and dirt, which
can cause premature wear of parts.
Wipe the scanner with a damp cloth occasionally
to keep it looking new. Do not use harsh chemi-
cals, cleaning solvents, or strong detergents to
clean it.
Modifying or tampering with the scanner’s internal components
can cause a malfunction and might invalidate its warranty and void
your FCC authorization to operate it. If your scanner is not operat-
ing as it should, take it to your local Radio Shack store for assis-
tance.
