Initializing the Scanner
Important:
 This procedure clears all frequencies you
stored in the scanner’s memory and initializes the scanner
to its default settings. Initialize the scanner only when you
are sure the scanner is not working properly.
1. Turn off the scanner, then turn it on again.
2. While holding down 
CLEAR, insert a pointed object,
such as a straightened paper clip, into the reset hole
on the side of the scanner. Then gently press and
release the reset button inside the opening. The dis-
play goes blank, then information reappears.
Note:
 You must release the reset button before you
release 
CLEAR. Otherwise, the memory might not
clear.
3. When the display reappears, release 
CLEAR.

CARE AND MAINTENANCE
Your RadioShack PRO-72 50-Channel Portable 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
minerals that can corrode the electronic
circuits.
Use and store the scanner only in normal
temperature environments. Temperature
extremes can shorten the life of electron-
ic devices, 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 type. Batteries can leak chemi-
cals 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.

Modifying or tampering with the scanner’s internal compo-
nents can cause a malfunction and might invalidate your
scanner’s warranty and void your FCC authorization to op-
erate it. If your scanner is not performing as it should, take
it to your local RadioShack store for assistance.
