top of your scanner, align the slots around the antenna’s connector with the studs on the antenna jack. Press the antenna down over the jack and turn the antenna’s base clockwise until it locks into place.

Connecting an Optional External Antenna

The antenna connector on your scanner makes it easy to use the scanner with a variety of antennas, such as an external mobile antenna or outdoor base station antenna. Your local RadioShack store sells a variety of antennas.

Always use 50-ohm coaxial cable, such as RG-58 or RG-8, to connect an outdoor antenna. For length over 50 feet, use RG-8 low- loss dielectric coaxial cable. If your antenna’s cable does not have a BNC connector, you will also need a BNC adapter (not supplied, available at your local RadioShack store).o

Follow the installation instructions supplied with the antenna, route the antenna cable to the scanner, then connect it to the antenna jack.

Connecting an Earphone/ Headphones

For private listening, you can plug an 1/8-inch (3.5 mm) mini-plug earphone or headphones (not supplied), available at your local RadioShack store, into the HEADPHONE jack on top of your scanner. This automatically disconnects the internal speaker.

oWARNING o

Use extreme caution when installing or removing an outdoor antenna. If the antenna starts to fall, let it go! It could contact overhead power lines. If the antenna touches a power line, touching the antenna, mast, cable, or guy wires can cause electrocution and death. Call the power company to remove the antenna. DO NOT attempt to do so yourself.
