Installation
Connecting the PowerCord
WARNING
This radio can be used only in vehicles with a negative ground electrical system.
Connecting this unit to a positive ground electrical system will result in serious
damage to the radio.
1. Check the vehicle battery connections to determine which battery terminal (positive
or negative) is grounded to the engine block or chassis. Most of today's automobiles
are negative ground.
2. Connect the REDwire of the DC power cord to the accessory contact in your
vehicle's +13.8 VDC fuse box.
3. Connectthe BLACKwire of the DC power cord to the negative side of the automobile
(usually the chassis).
Mounting the Microphone Hanger
Mountthe microphone hanger on the side of the
radio. Mounting holes are provided on the
right-hand side of the unit. Use the screws
supplied. You can also mount the hanger on the
dashboard if preferred.
~
Mounting the Radio Bracket
The design of the PRO501XLMounting Bracket
allows you to mount the radio in one of three angles for easy viewing of the front panel.
Note: The speaker is located on the bottom of the radio. Be sure the mounting
location does not obstruct this area.
Note: Mount the radio to the bracket only after the wiring has been connected to the
rear panel and the microphone hanger has been installed
1. First select an ideal location in yo~r vehicle to mount the PRO501XL. Make sure the
location will not interfere with your driving. In a passenger car, the ideal installation
is underneath the dashboard on the passenger side.
2. Remove the mounting bracket from the radio and use it as a template for marking
the location of the mounting screws. (Note: If there are screws already holding the
dashboard, you can use the same screw holes to mount the bracket in its place.)
3. Drill the necessary holes and secure the mounting bracket in place using the screws
provided.

4. Secure the radio to the mounting bracket with
the provided mounting knobs (2).
5. To mount the radio at an angle:
.Loosen the mounting knobs.
.Tilt the radio.
.Tighten the mounting knobs.
Connecting the Microphone
Plug the Microphone Cord connector into the jack on the left-hand side of the radio.
Connecting the Antenna
Connect the CB antenna plug to the ANT. jack on the rear panel. (For more information
on antenna installation, please refer to the instruction guide that came with your
antenna.)
CB Antenna TIps
.In mobile installations (cars, trucks, or boats, etc.), use a non-directional antenna
system for maximum transmitting and receiving performance.
.A vertically polarized, quarter-wavelength whip antenna provides the most reliable
operation and greatest range.
.A 3-way combination antenna allows you to operate all three bands (AM, FM, and
CB) with one antenna. However, it will provide a far less transmitting and receiving
range than a standard "single band" antenna designed for CB use only.
.The shorter loaded-type whip antennas are more attractive and compact than the
larger full quarter-wavelength whip. However, the shorter antennas will not provide
the maximum transmitting and receiving range that is possible with the larger ones..
