2. Slide the antenna's connector down over the scanner's
connector.
3. 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 50 feet from the scanner,
use RG-8 low-loss dielectric coaxial cable. If it is less than 50 feet,
use RG-58. You can get a BNC adapter at local electronics stores.
CONNECTING AN EARPHONE/HEADPHONE
For private listening, you can plug a 1/8-inch (3.5 mm) mini-
plug earphone 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 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.
