Actions
1. Plan the mounting locations of all
components (Radio, Antenna, and
Cables) and determine the routes for
all wiring and cables.
Notes
Determine the customer’s preferences, if any, for
location of components. Comply with these
preferences insofar as they are consistent with
safety, manufacturer specifications, and
generally accepted professional practices.
Make certain that drilling holes or inserting
screws will not damage or interfere with any
existing vehicle components or wiring. Follow all
manufacturer requirements and guidelines for the
location of components.
2. Mount the bracket in the interior of the
vehicle.
Mount the Base Bracket (Item 1) on top of the
floor of the trunk according to the available space
in the vehicle or on the surface of a trunk tray.
Screws for mounting the bracket are not
included, as all installations are different. The
bracket must be firmly held to the surface in
order to prevent unreasonable vibration from
damaging the radio or loosening connections.
3. Mount the Radio onto the Bracket.
Install the Mobile Radio into the bracket using the
6 screws (Item 8) and tighten with a screwdriver
until the bracket is firm and flush to the surface of
the radio. (Note: With 2 packages of 4 screws,
there will be 2 extra screws.)
4. A CAN Terminator is needed to
terminate the CAN Port.
Install the CAN Terminator (Item 5) onto the front
of the Radio and tighten the screws with a
screwdriver.

5. Mount the Antenna at a suitable
location on the vehicle, and route the
Antenna Cable inside the vehicle for
connection to the Radio.
NOTE
Improper
installation of the antenna may
lead not only to poor radio
performance, but to harmful
exposure as well. See Antenna
Mounting Configurations below.
The Antenna (Item 2) that is included in the kit
must be mounted by drilling a hole. The optimal
position of the antenna is in the direct center of
the roof of the vehicle. Refer to Antenna
Mounting Configurations for requirements
necessary to follow when selecting the proper
mounting area for the antenna. Also, refer to the
antenna manufacturer’s mounting and testing
instructions included in the Antenna Assembly kit
for installation guidance once the mounting area
is determined.
Route the cable from the Antenna (Item 2) to the
rear of the Radio out of the way of casual
contact. Install the Mini-UHF connector of the
cable to the mating connector at the rear of the
cable by tightening until finger-tight. It is
important that this connector is tight to prevent
RF leakage from occurring, but not too tight that
damage occurs.
Do not connect the antenna cable to the Radio
until satisfactory completion of testing into a
dummy load (refer to Testing Into a Dummy
Load).
6. If an optional GPS unit is included in
the Radio, the GPS Antenna needs to
be connected to the Radio.
Connect the SMA connector of the GPS Antenna
(Item 11) cable to the SMA connector on the rear
of the Radio and route the cable out of the way of
casual contact. The GPS Antenna is to be
mounted on the roof of the vehicle with one of
the 3 mounting configurations: Show-Mount, No
Show-Mount, and Magnetic Mount. The Antenna
must be kept at least 1 foot from any other
antenna mounted on the vehicle and have at
least 6 inches of ground plane beneath it.
7. Prepare for connecting the power to
the Radio through the vehicle’s
firewall.
Plan the cable route carefully, using an existing
access hole through the engine firewall if
possible. Alternatively, drill a new hole
approximately 3/8" in diameter and install a
rubber grommet to protect the cable.

8. The Fuse for Radio power must be
installed in-line with raw battery
voltage.
Strip one end of the wire included in the Fuse Kit
(Item 3) and crimp the terminal lug onto it. Cut
the wire to a length of about 6 inches and strip
the end to a length indicated by the gauge on the
fuse holder. Insert this end into the fuse holder
until the wire cannot go any further and crimp the
connection to the fuse holder. Use heat-shrink
tubing to protect the connection from foreign
materials. Connect the remaining wire in a similar
fashion to the other end of the fuse holder.
Connect the terminal to the vehicle’s battery in
the engine compartment. Route the wire through
a wire loom and pass it through the firewall using
a grommet to ensure the wire is not damaged.
9. Prepare the ground and sense
connections prior to applying power to
the Radio.
Connect the DC Power Cable (Item 4) to the 3pin connector at the rear of the Radio. Locate a
chassis ground close to the Radio and strip back
any jacket insulation around the wires to allow for
the shortest distance of the black wire. Cut the
negative (black) wire as short as possible, strip it,
and crimp the terminal to it. Screw it into the
chassis ground, ensuring a reliable metal-tometal contact.
Connect the sense (white) wire of the DC Power
Cable (Item 4) to an appropriate terminal to
connect to a fused ignition sense in the fuse box
and route the excess wire out of the way of
casual contact.
10. Apply the DC power connection to the
Radio.
NOTE
Using a pigtail, butt-splice, or solder-sleeve,
connect the positive (red) wire of the DC Power
Cable (Item 4) to the fuse wire (Item 3) and route
the excess wire out of the way of casual contact.
Unlike many mobile
radios, the OpenSky® Mobile Radio
powers up immediately upon
application of DC power.
11. Test the output of the installed Radio
into a dummy load to verify that it
meets specifications.

12. Connect the Antenna and test the
Radio’s forward and reflected power
to verify transmission performance.
Refer to Testing With the Antenna under Testing
below for the procedure.
13. Complete the installation by
organizing, securing, and checking all
cables and components.
Take whatever steps are practical to make the
installation neat and functional for the Radio’s
user. Organize and secure all cables; make sure
all connections are tight.
TESTING
This section sets forth procedures to verify the performance of the installed radio.
Testing uses a wattmeter (or, alternatively, a VSWR meter) to measure RF power.
There are three procedures in this section: Changing Operating Modes, Testing Into
a Dummy Load, and Testing With the Antenna. Note that while the radio’s normal
operating mode for voice or data communications is OpenSky® Trunking Protocol
(OTP), the radio must be operating in OpenSky® Conventional FM (OCF) mode for
testing. Follow the procedure under Changing Operating Modes to switch between
the OCF and OTP modes.
Note also that the accuracy of test results depends on a radio power source in the
range of 13.8–16 volts DC at greater than 8 amps. Make sure the vehicle’s battery is
fully charged by running the engine for a few minutes before the test, and keep the
engine running during the test procedures.

Antenna Mounting Configurations
This radio has been tested and complies with the FCC RF exposure limits for
Uncontrolled Exposure and Occupational exposure. The difference is in the minimum
safe distance that people must be away from the antenna when transmitting RF
energy. To assure optimal radio performance and that human exposure to RF
electromagnetic energy is within the guidelines, transmit only when people are at least
the minimum distance away from a properly installed antenna. Table II lists the
minimal distances.

There are various vehicles that have various physical dimensions that are not
standard, so selection of an antenna location is not trivial. Using Table II as a guide for
determining the best possible mounting configuration in order to reduce human
exposure, there are three possible locations on a vehicle where the antenna can be
mounted, described as follows:
Rooftop Center (Items 1 and 2 above) The center of the roof of a vehicle is the optimal
location for the rooftop antenna. The mounting area under the antenna must be a flat,
metallized ground plane, and it must be located directly in the center of the roof. If
other obstructions, such as a light bar or another antenna, prevent the antenna from
being mounted in the direct center of the roof, the antenna should be mounted,
preferably, a minimum of one foot away from the obstruction, but in the middle of the
roof with respect to the left and right sides of the vehicle.
Trunk-Lid Center (Items 1, 2, and 3 above) Certain vehicles do not allow for the
antenna to be placed in the center of the roof. In this case, the next optimal location for
the antenna is in the center of the trunk lid. Again, the mounting area under the
antenna must be a flat, metallized ground plane, and it must be located directly in the
center of the trunk lid. There are no other preferable solutions for mounting this
antenna if other obstructions prevent the antenna from being mounted in the direct
center of the trunk lid.
Trunk-Lip Center (Items 3 above only) Only the third choice of antennas above allows
for a configuration for a trunk-lip mount for the antenna. In this case, the antenna is
mounted on the top lip and in the direct center of the trunk lid. Again, there are no
other preferable solutions for mounting this antenna if other obstructions prevent the
antenna from being mounted in the direct top center of the trunk lid.

TARGET VALUE RANGE
If the wattmeter reading is within the
target range, record the value in the
appropriate space on the data collection
sheet at the end of this guide.
If the wattmeter reading is outside the
target range, make sure the antenna
installed is consistent with the radio’s
specified frequency range. Recheck all
antenna connections, and measure the
reverse power again. If this fails to
produce a reading within the target
range, replace the antenna and repeat
the entire testing procedure.
Any value exceeding the maximum
allowable reflected power value will
result in a diminished radio output
The standard measure for comparing forward and reflected power is the Voltage Standing Wave Ratio (VSWR). Use the
values recorded for the installed radio’s forward and reflected power to compute the VSWR, if desired, using the following
formula: VSWR = 1 +
PR PF , where PR = reverse power and PF = forward power. This value is expressed as a ratio to
the ideal value of 1, for instance, 1.2:1.
