Removing the Display Sticker
Before you use the scanner for the first time, remove the protective plastic film over the display.
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- or 75-ohm, RG-58, or RG-8, BNC terminated 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. 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 the front of your scanner.
This automatically disconnects the internal speaker. See the
for important information about using an earphone/headphone.
WARNING!
Never connect anything other than the recommended amplified extension speaker to the scanner’s headphone jack. Damage to the scanner might
occur.
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 back-panel Ext. Sp. Jack.
WARNING!
Never connect any part of the headphone jack to the antenna jack or connect the radio to an installation where the antenna and audio connection are
grounded. This might also damage the scanner.
