The rubber feet help prevent sliding o
n smooth surfaces, and will help prevent scratching of your desk or
tabletop. Do not use the rubber feet if you plan to attach the mounting bracket to a fixed surface with
screws.
Attach the two self-adhesive rubber washers to the inside of the mounting bracket sides, over the holes that
are used when attaching the bracket to the scanner’s side holes. Be sure to align the holes in the washer
carefully with the holes in the mounting bracket. The rubber washers help protect the scanner’s case from
scratches.
Slide the scanner carefully into the mounting bracket assembly, and use the two provided knurled knobs to
secure the scanner within the mounting bracket.
Connect the supplied DC power supply to your wall outlet. Connect the coaxial power plug to the radio.
! WARNING
To prevent electric shock, do not use the AC adaptor’s polarized plug with an extension cord, receptacle, or
other outlet unless you can fully insert the blades to prevent blade exposure.
Caution
. You must use a supplied AC adaptor.
. The correct orientation for the enclosed power adaptor is in a vertical or floor-mount position.
Note: Plug the adaptor into an easily accessible power outlet located near the equipment.
Attach the supplied antenna to the radio.
Your scanner’s sensitivity to various frequencies depends on its location and the antenna’s length. For best
reception, adjust the antenna’s length as follows:

108-174 MHz Extend 4 segments
216-225 MHz Extend 3 segments
225-406 MHz Extend 2 segments
406-1300 MHz Collapse fully
Note: If desired, you may also connect an external base station antenna feedline equipped with a BNC
male connector to the antenna connector. Please refer to the section entitled “Connecting an Optional
External Antenna” below for important instructions and warnings.
