Setting Up Your Scanner
Connecting the Antenna
To attach the supplied flexible antenna to the
connector on the top of your scanner, simply screw it
onto the scanner's SMA connector.
Connecting an Optional Antenna
The scanner's SMA 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- or 75-ohm, RG-58, or RG-8,
coaxial cable and the supplied BNC/SMA adapter to
connect an outdoor antenna. If the antenna is over 50
feet from the scanner, use RG-8 low-loss dielectric
coaxial cable. Cable loss increases with higher frequency.
Connecting an Earphone/Headphone
For private listening, you can plug a
1
/8-inch (3.5 mm)
mini-plug earphone or headphones (not supplied) into
the headphone jack on top of your scanner. This
automatically disconnects the internal speaker.
See “Earphone Warning” at the front of the manual for
important information about using an earphone/
headphone.
Connecting an Extension Speaker
In a noisy area, an optional amplified 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!
Never connect anything other than an earphone or
the recommended amplified extension speaker to
the scanner’s headphone jack. This might damage
the scanner.
