Connecting the Antenna

Attach the supplied antenna
to the scanner by screwing it
tightly onto the anchor post at
the top of the scanner.
When using an external
antenna, always use 50-ohm,
RG-58, or RG-8, coaxial
cable to connect to it. If the
antenna is over 50 feet from
the scanner, use RG-8 low-loss
dielectric coaxial cable. If your
antenna's cable does not have
an SMA connector, your local
RadioShack store carries a
variety of SMA adapters.

Attaching the Belt Clip

1. Align the belt clip so that
the finger indentation is
towards the top of the
scanner.
2. Align the center of the clip with the anchor
post.
3. Place the clip on the post and slide the clip
upwards until it clicks into place.
To remove the belt clip:
1. Rotate the clip so that the finger indentation
is towards the bottom of the scanner.
2. Slide the clip up until it comes free of the
anchor post.

Powering Your Scanner

You can power your scanner with three AA
batteries (not supplied) or an external power
source (not supplied).
