FREQUENCY CONVERSION
The tuning location of a station can be expressed in fre-
quency (kHz or MHz) or in wavelength (meters). The fol-
lowing information can help you make the necessary
conversions.
1 MHz (million) = 1,000 kHz (thousand)
To convert MHz to kHz, multiply the number of mega-
hertz by 1,000:
30.62 (MHz) ´
 1000  = 30,620 kHz
To convert from kHz to MHz, divide the number of kilo-
hertz by 1,000:
127,800 (kHz) ¸
 1000 = 127.8 MHz
To convert MHz to meters, divide 300 by the number of
megahertz:
300 ¸
 50 MHz = 6 meters

TROUBLESHOOTING
If you have problems with your scanner, here are some
suggestions that might help you eliminate the problem. If
they do not, take your scanner to your local Ra-
dioShack store for assistance.
Problem Possible Cause Remedy
Scanner is on 
but will not 
scan.
SQUELCH is not 
adjusted cor-
rectly.Turn SQUELCH clock-
wise. See “Turning on 
the Scanner and Setting 
Squelch” on Page 35.
Scanner is 
totally inoper-
ative.No power. Check the batteries or 
make sure the AC 
adapter or DC adapter 
is connected properly.
Recharge the recharge-
able batteries or replace 
the non-rechargeable 
batteries.
The AC adapter 
or DC adapter is 
not connected.Be sure the adapter’s 
barrel plug is fully 
plugged into the 
PWR 
DC 9V jack.
The batteries 
may be improp-
erly installed.Make sure the batteries 
are properly installed 
according to polarity 
markings on the battery 
holder.
Poor or no 
reception.An antenna is 
not connected or 
connected incor-
rectly.Make sure an antenna 
is connected to the 
scanner.
Programmed fre-
quencies are the 
same as birdie 
frequencies.Avoid programming 
birdie frequencies or 
only select them manu-
ally. See “Birdie Fre-
quencies” on Page 65.
Keypad does 
not work.Keylock is turned 
on.Turn off keylock.

In the scan 
mode, the 
scanner locks 
on frequen-
cies that have 
an unclear 
transmission.Stored frequen-
cies are the 
same as “birdie” 
frequencies.Avoid storing birdie fre-
quencies or only select 
them manually. See 
“Birdie Frequencies” on 
Page 65. 
Keys do not 
work or dis-
play changes.Undetermined 
error.Turn the scanner off 
then on again, or reset 
the scanner. See 
“Resetting/Initializing 
the Scanner” on Page

RESETTING/INITIALIZING THE 
SCANNER
If the scanner’s display locks up or does not work proper-
ly after you connect a power source, you might need to
reset or initialize it.
Important: If you have problems with the scanner, first
try to reset it to retain all memory. If that does not work,
you can initialize the scanner; however, initializing clears
all information stored in the scanner’s memory.
Resetting the Scanner
1. Turn off the scanner, then turn it on again.
2. Insert a pointed object, such as a straightened paper
clip, into the reset opening on the side of the scan-
ner. Then gently press and release the reset button
inside the opening and the backlight lights.
Note: Pressing 
RESET does not clear the scanner’s
memory.
Initializing the Scanner
Important: This procedure clears all information you
stored in the scanner’s memory. Initialize the scanner
only when you are sure the scanner is not working prop-
erly.
1. Turn off the scanner, then turn it on again. 
Wel-
come
 To Multi-System Trunking appears
on the display.

 Multi-System Trunking. Initializ-
ing

25 seconds.
Note: Do not turn off the scanner until the initializa-
tion is complete and 
Welcome To Multi-Sys-

CARE AND MAINTENANCE
Your RadioShack PRO-92 500-Channel Portable Trunk-
ing Scanner is an example of superior design and crafts-
manship. 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 can contain miner-
als that can corrode the electronic circuits.
Use only batteries of the recommended
size and type. Always remove old and weak
batteries. They can leak chemicals that de-
stroy electronic circuits.
Handle the scanner gently and carefully.
Dropping it can damage circuit boards and
cases and can cause the scanner to work
improperly.
Use and store the scanner only in normal
temperature environments. Temperature
extremes can shorten the life of electronic
devices, damage batteries, 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 occa-
sionally to keep it looking new. Do not use
harsh chemicals, cleaning solvents, or
strong detergents to clean the scanner.
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.
