PREPARATION
This scanner is designed primarily for
use in the home as a base station.
You can place it on a desk, shelf, or
table.
Your scanner’s front feet fold up or
down. Adjust them to give you the
best view of the display.
Your scanner’s display is protected
during shipment by a piece of film.
Peel off this film before you use the
scanner.

• The antenna should be as high as
possible on the vehicle or build-
ing.
• The antenna and its cable should
be as far as possible from sources
of electrical noise (appliances,
other radios, etc.).
• The antenna should be vertical for
the best performance.
To connect an optional base-station or
mobile antenna, first remove the sup-
plied antenna from the scanner. Al-
ways use 50-ohm coaxial cable, such
as RG-58 or RG-8, to connect the
base-station or mobile antenna. For
lengths over 50 feet, use RG-8...

10 Cautions:
You must use a Class 2
power source that sup-
plies 12V DC and deliv-
ers at least 500 mA. Its center tip
must be set to positive and its
plug must fit the scanners 
DC 12V
jack. The supplied adapter meets
these specifications. Using an
adapter that does not meet these
specifications could damage the
scanner or the adapter.
• Always connect the AC adapter to
the scanner before you connect it
to AC power. When you finish, dis-
connect the adapter from AC
power before you disconnect it
