PSR-200U Owner’s Manual Draft
centre tip must be set to positive and its plug must fit the scanner's DC 9V jack. Using an
adaptor that does not meet these specifications could damage the scanner or the adaptor.
Cautions: Always connect the DC adaptor to the scanner before you connect it to the power
source. When you finish, disconnect the adaptor from the power source before you
disconnect it from the scanner.
To power the scanner using a DC adaptor, connect the plug into the scanner’s DC 9V jack.
Plug the other end of the DC adaptor into your vehicle’s cigarette-lighter socket.
Note: If you use a cigarette-lighter DC 9V adaptor and your vehicle’s engine is running, you
might hear electrical noise from the engine while scanning. This is normal.
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.
Frequency Antenna Length
29-174 MHz Extend fully
380-512 MHz Extend 2 segments
Connecting an Outdoor Antenna
The antenna connector on your scanner makes it easy to use the scanner with a variety of
antennas, such as an external mobile antenna or outdoor base station antenna.
Always use 50 Ohm coaxial cable, such as RG-58 or RG-8, to connect an outdoor antenna.
For lengths over 50 feet, use RG-8 low-loss dielectric coaxial cable. If the antenna cable’s
connector does not have a BNC connector, you will also need a BNC adaptor.
