Radio Shack PRO-528 manual Connecting the antenna, Connecting an earphone/ headphone

The Basics

•Always connect the AC adapter to the scanner before you connect it to AC power. When you finish, disconnect the adapter from AC power before you disconnect it from the scanner.

connecting the antenna

Attach the supplied antenna to the scanner by align the slots around its base with the tabs on the scanner, then slide into place.

When using an external antenna, always use 50-ohm, RG-58, or RG-8, coaxial cable to connect to it. If the antenna is over 50 feet from the scanner, use RG-8 low-loss dielectric coaxial cable. If your antenna’s cable does not have a BNC connector, your local RadioShack store carries a variety of BNC adapters.

connecting an earphone/ headphone

For private listening, you can plug headphones (not included) into the headphone jack on top of your scanner. This automatically disconnects the internal speaker. Note that the sound is “mono” and not stereo.
