Scanner Setup
To remove your scanner from
the DIN sleeve, insert the two
keys straight into the scanner’s
front panel and pull the
scanner out.
Connecting the Antenna
You must install an antenna
before you can operate
the scanner. The supplied
telescopic antenna helps
your scanner receive strong
local signals. To install the
antenna, align the antenna
slots with the tabs on the
scanner, and slide the
antenna into place. Turn
and push down until the
antenna locks into place.
To connect an external antenna, follow the installation instructions
supplied with the antenna. Use 50-ohm coaxial cable, such as RG-58
or RG-8X, to connect an outdoor antenna. For lengths between 50
and 100 feet, use RG-8X low-loss dielectric coaxial cable. For lengths
over 100 feet, use RG8. You also may need a BNC adapter (not
supplied).
WARNING: Use extreme caution when you 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, contact with 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.
Powering Your Scanner
You can power your scanner from a wall outlet, or from your vehicle’s
battery.
You must use a power source that supplies 12V DC and delivers at
least 600 mA. Its center tip must be set to positive and its plug must
fit the scanner’s DC 13.8V jack. The supplied AC adapter and DC
power cord meet these specifications. Using a power source that
does not meet these specifications could damage the scanner or the
adapter.
Wall Outlet
1. Connect the tip of the supplied AC adapter to the DC 13.8V jack
at the rear of your scanner.
2. Plug the AC adapter into your wall outlet.
To prevent electric shock, do not use the AC adapter’s polarized
plug with an extension cord, receptacle, or outlet unless you can fully
insert the blades to prevent blade exposure.
Note: To avoid injury, do not connect the provided power adapter to
a ceiling outlet.
Vehicle (Power Socket)
To power your scanner from a 12V power source in your vehicle, such
as a cigarette-lighter socket, you need a 12V, 600 mA DC cigarette-
lighter adapter (not supplied), available at your local RadioShack
store.
1. Insert the adapter’s barrel plug into the scanner’s DC 13.8V jack.
2. Plug the adapter’s other end into your vehicle’s cigarette lighter
or power socket.
Note: When you use a cigarette-lighter adapter, you might hear
electrical noise from your engine while scanning. This is normal. This
is less of a problem if you connect directly to the vehicle fuse box.
