•If you use your scanner in your vehicle with the engine running, you might hear electrical noise from the scanner. This is normal.

Note: Mobile use of this scanner is unlawful or requires a permit in some areas. Check the laws in your area.

Follow these steps to use vehicle bat- tery power.

DC 12V

1.Insert the DC power cord’s barrel plug into the scanner’s DC 12V jack.

2.Plug the DC power cord’s ciga- rette-lighter plug into your vehi- cle’s cigarette-lighter socket.

CONNECTING AN

ANTENNA

You can connect either the supplied telescoping antenna or an optional an- tenna to your scanner.

Telescoping Antenna

The supplied telescoping antenna helps your scanner receive strong lo- cal signals. Follow these steps to in- stall the supplied antenna.

ANT

1. Hold the antenna so it stands straight up.

2. Gently push the antenna’s plug onto the ANT jack on the scan- ner’s back panel.

The antenna’s length affects recep- tion. Adjust the antenna’s length as follows for the best results.

29–150 MHz	Extend fully

150–174 MHz	Extend only 3 seg-
	ments

216–406 MHz	Extend only 2 seg-
	ments

406–1000 MHz	Collapse Fully (only
	1 segment extended)

Optional Outdoor Antenna

The supplied antenna is usually good for strong, local signals. However, for the best results in receiving weaker, more distant signals on all bands, you can attach an optional outdoor anten- na (not supplied), such as a mobile, telescoping, multi-band, or outdoor base antenna.

Warning: When installing or removing an outdoor antenna, follow all cautions and warnings included with the anten- na.
