To attach the supplied flexible antenna to the connector on the
top of your scanner, align the slots around the antenna's
connector with the tabs on the scanner's BNC connector. Then
slide the antenna's connector down over the scanner's
connector and rotate the antenna connector's outer ring
clockwise until it locks into place.
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 15 m from
the scanner, use RG-213/U or “air cell” type low loss coaxial
cable. You can get a BNC adapter at your local electronics
store.
Connecting an Earphone/ ext. Speaker
For private listening, you can plug a 3.5 mm miniplug earphone
or mono or stereo 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 3.5- mm mini-plug into your scanner's jack. For
larger audio power, active speakers (like used for PC’s) are
recommended.
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.
