5. Reconnect the cable to the negative (-) terminal of your vehicle’s battery.
FROM YOUR VEHICLE’S SIGARETTE LIGHTER
To power your scanner from a 12V power source in your vehicle, such as a cigarette-lighter socket, you need a
12V, 1A DC
cigarette-lighter adapter (not supplied), available at your local RadioShack store.
1. Insert the adapter’s barrel plug into the scanner’s DC 12V jack.
2. Plug the adapter’s other end into your vehicle’s cigarette lighter or power socket.
Step 3: connect your scanner
CONNECTING THE SUPLLIED ANTENNA
Plug the telescoping antenna into the ANT connector. The antenna length should be as shown below.
Frequency
Antenna Length
25-174 MHz Extend fully (4 segments)
400-512 MHz Extend 2 segments
806-1300 MHz Collapse fully (1 segment)
CONNECTING AN EXTERNAL ANTENNA
The ANT jack on the back of the scanner makes it easy to use the scanner with a variety of antennas.
You will need to connect an external antenna when you mount your scanner in the dashboard of your vehicle.
You may also want to connect an external antenna if you use your scanner as a base station.
Your local RadioShack store sells a variety of antennas. Always use 50-ohm coaxial cable, such as RG-58 or
RG-8, to connect an outdoor antenna. For lengths exceeding 50 feet, use RG-8 low-loss dielectric coaxial cable.
If your coaxialcable does not have a BNC connector, you will also need a BNC adapter (not supplied).
When deciding on an antenna and its location, consider the following:
• The location of the antenna should be 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.
Note: Use extreme caution when installing or removing an outdoor antenna. If the antenna starts to fall, let it go!
It could contact overhead power lines. If the antenna touches a power line, touching the antenna, mast, cable,
or guy wires can cause electrocution and death. Call the power company to remove the antenna. Do not attempt
to do so yourself.
CONNECTING AN EXTERNAL SPEAKER
If you mount the scanner in your dashboard or if you use it in a noisy area, you may want to add an external
speaker (available at your local RadioShack store) to improve your ability to hear. Plug the speaker cable’s 1/8
inch (3.5 mm) plug into your scanner’s EXT SP jack.
Note: Connecting an external speaker disconnects the scanner’s internal speaker.
