Setting Up Your Scanner
Connecting an Optional Antenna
The scanner's BNC connector makes it easy to
connect a variety of optional antennas, including an
external mobile antenna or outdoor base station
antenna.
Note: Always use 50-ohm, RG-58, or RG-8, coaxial
cable to connect an outdoor antenna. If the antenna
is over 50 feet from the scanner, use RG-8 low-loss
dielectric coaxial cable. You can get a BNC adapter
at your local electronics store.
Connecting an Earphone/Headphone
For private listening, you can plug a
1
/8-inch (3.5
mm) mini-plug earphone or mono headphones (not
supplied) into the headphone jack on top of your
scanner. This automatically disconnects the internal
speaker.
Connecting an Extension Speaker
In a noisy area, an optional extension speaker,
positioned in the right place, might provide more
comfortable listening. Plug the speaker cable's
1
/8-
inch (3.5-mm) mini-plug into your scanner's jack.
WARNING!
If you connect an external speaker to the scanner's
headphone jack, never connect the audio output line
to a power supply and ground. This might damage
the scanner.
