The antenna should be as high as possible on the vehicle or build- ing.

The antenna and its cable should be as far as possible from sources of electrical noise (appliances, other radios, etc.).

The antenna should be vertical for the best performance.

To connect an optional base-station or mobile antenna, first remove the sup- plied antenna from the scanner. Al- ways use 50-ohm coaxial cable, such as RG-58 or RG-8, to connect the base-station or mobile antenna. For lengths over 50 feet, use RG-8 low- loss dielectric coaxial cable. If the an- tenna cable’s connector does not fit in the ANT. jack, you might also need a Motorola-to-BNC antenna plug adapt- er, such as RadioShack Cat. No. 278-

117.Your local RadioShack store car- ries a wide variety of coaxial antenna cable and connectors.

Once you choose an antenna, follow the mounting instructions supplied with the antenna. Then route the an- tenna’s cable to the scanner and con- nect the cable to the ANT. jack on the back of the scanner.

Cautions:

Do not run the cable over sharp edges or moving parts that might damage it.

Do not run the cable next to power cables or other antenna cables.

Warning: Use extreme caution when you install or remove an out- door antenna. If the antenna starts to fall, let it go! It could contact over- head power lines. If the antenna touches a power line, contact with the antenna, mast, cable, or guy wires can cause electrocution and death. Call the power company to re- move the antenna. DO NOT attempt to do so yourself.

CONNECTING POWER

Using AC Power

The scanner’s supplied AC adapter lets you power the scanner from a standard AC outlet. To connect power to the scanner, insert the AC adapter’s barrel plug into the DC 12V jack on the back of the scanner, then plug the AC adapter into a standard AC outlet.
