• If you use your scanner in your
vehicle with the engine running,
you might hear electrical noise
from the scanner. This is normal.
Note: Mobile use of this scanner is
unlawful or requires a permit in some
areas. Check the laws in your area.
Follow these steps to use vehicle bat-
tery power.
1. Insert the DC power cord’s barrel
plug into the scanner’s
DC 12V
jack.
2. Plug the DC power cord’s ciga-
rette-lighter plug into your vehi-
cle’s cigarette-lighter socket.
CONNECTING AN
ANTENNA
You can connect either the supplied
telescoping antenna or an optional an-
tenna to your scanner.
Telescoping Antenna
The supplied telescoping antenna
helps your scanner receive strong lo-
cal signals. Follow these steps to in-
stall the supplied antenna.
1. Hold the antenna so it stands
straight up.
2. Gently push the antenna’s plug
onto the
ANT
jack on the scan-
ner’s back panel.
The antenna’s length affects recep-
tion. Adjust the antenna’s length as
follows for the best results.
Optional Outdoor Antenna
The supplied antenna is usually good
for strong, local signals. However, for
the best results in receiving weaker,
more distant signals on all bands, you
can attach an optional outdoor anten-
na (not supplied), such as a mobile,
telescoping, multi-band, or outdoor
base antenna.
Warning: When installing or removing
an outdoor antenna, follow all cautions
and warnings included with the anten-
na.
