RESETTING THE SCANNER
If the scanner’s display locks up or stops operating
properly, you might need to reset the scanner. 
Caution:
 This procedure clears all the information you
have stored in the scanner. Before you reset the scan-
ner, try turning it off and on to see if it begins working
properly. Reset the scanner only when you are sure it is
not working properly.
1. Turn off the scanner.
2. While holding down the 
2 and 9 keys, turn on the
scanner. 
CLEAR flashes for about 5 seconds as
the scanner clears its memory. 
Note:
 Do not turn off the scanner again until 
CLEAR
stops flashing. Otherwise, the scanner might not clear
its memory properly.
Channel activity 
bars are flashing 
but no sound is 
heard.The transmis-
sion might be a 
private or tele-
phone intercon-
nect call. The 
scanner does not 
scan these types 
of transmissions.Scan for another 
transmission.
The ID shown is 
not active.Wait for the ID to 
become active, or 
scan another 
transmission. Problem Possible Cause Remedy

CARE AND MAINTENANCE
Modifying or tampering with the scanner’s internal com-
ponents can cause a malfunction, invalidate your scan-
ner’s warranty and void your FCC authorization to
operate it. If your scanner is not operating as it should,
take it to your local RadioShack store for assistance.Your RadioShack PRO-94 1000-Channel Handheld
Trunking 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 immediately. Liquids might contain min-
erals that can corrode the electronic circuits.
Use and store the scanner only in normal
temperature environments. Temperature ex-
tremes can shorten the life of electronic de-
vices, damage batteries, and distort or melt
plastic parts.
Keep the scanner away from dust and dirt,
which can cause premature wear of parts.
Handle the scanner gently and carefully.
Dropping it can damage circuit boards and
cases and can cause the scanner to work
improperly.
Use only fresh batteries of the required size
and recommended type. Batteries can leak
chemicals that damage your scanner’s elec-
tronic parts.
Wipe the scanner with a damp cloth occa-
sionally to keep it looking new. Do not use
harsh chemicals, cleaning solvents, or
strong detergents to clean the scanner.
