Notes

:

• If you use a 12V DC cord and your

vehicle's engine is running, you might

hear electrical noise on the scanner

caused by the engine. This is normal.

• Mobile use of this scanner is unlawful or

requires a permit in some areas. Check

the laws in your area.

CONNECTING AN ANTENNA

Connecting the Supplied Antenna

You must install an antenna before you can

operate the scanner.

The supplied telescoping antenna helps your

scanner receive strong local signals. To

install the antenna, thread it clockwise into

the hole on top of the scanner.

The scanner's sensitivity depends on its

location and the antenna's length. For the

best reception of the transmissions you want

to hear, adjust the antenna's length

according to the chart below.

Connecting an Outdoor Antenna

Instead of the supplied antenna, you can

connect an outdoor base-station or mobile

antenna (neither supplied) to your scanner.

Your local RadioShack store sells a variety

of antennas. Choose the one that best meets

your needs.

When deciding on an outdoor antenna and

its location, consider these points:

• The antenna should be located as high

as possible.

• The antenna and antenna cable should

be as far as possible from sources of

electrical noise (appliances, other

radios, and so on).

• The antenna should be vertical for the

best performance.

To connect an optional base-station or

mobile antenna, first remove the supplied

antenna from the scanner. Always 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

antenna cable's connector does not fit in the

ANT

jack on the back of the scanner, you

might also need a PL-259-to-Motorola

antenna plug adapter. 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 antenna's cable to
