To connect an optional base-station antenna, first remove the supplied an- tenna from the scanner. Always use 50-ohm coaxial cable, such as RG-58 or RG-8, to connect the base-station antenna. For lengths over 50 feet, use RG-8 low-loss dielectric coaxial cable. If the antenna cable’s connector does not fit in the ANT. jack, you might also need an antenna plug adapter such as RadioShack Cat. No. 278-208. Your local RadioShack store carries 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.

•Follow all cautions and warnings included with your antenna.

CONNECTING 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 AC 10V jack on the back of the scanner, then plug the AC adapter into a standard AC outlet.

P 8

Warning: Do not use the AC adapt- er’s polarized plug with an extension cord receptacle unless the blades can be fully inserted to prevent blade ex- posure.

Cautions:

You must use a Class 2 pow-

!er source that supplies 10 volts AC and delivers at least

300 mA. Its plug must fit the scanner's AC 10V jack. The supplied adapter meets these specifications. Using an adapter that does not meet these specifications could damage the scan- ner or the adapter.
