Notes
The Fuse must not
be installed in the
Fuse Holder until all
wiring is complete.
IMPORTANT This will prevent the
V-TAC from
powering up prematurely and
causing an in-rush of current that
could lead to shorting of the
battery, sparking, or even fire.
IMPORTANT
♦
Open the fuse holder and remove the fuse.
♦
Insert the stripped wire into the fuse holder
and push out the holder socket.
♦
Crimp the socket onto the wire at the crimp
end and pull the wire so that the socket seats
back into the 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.
♦
Mark or label the wire to indicate that the inline fuse is 3 Amps.
♦
Route the wire at the other end through a
wire loom and pass it through the firewall,
using a grommet to ensure that the wire is
not damaged.
♦
Repeat the procedure above for the two 15A
fuse kits (Item 4). Mark or label these wires
to indicate the in-line fuses are 15 Amps.
Labeling of the fuse wires is important so that proper connection of the
three units of the V-TAC is obtained. The RF Combiner uses less
current than the MRU and VRB and is therefore rated at a lower
current. Connecting either the VRB or MRU to the 3A fuse will result in
an over-current event and cause the V-TAC to fail.

♦
Locate a chassis ground close to the V-TAC
and strip away any paint or dirt to expose
raw metal. The location of this connection
should be as close to the V-TAC that the
installation will allow.
♦
Cut the negative (black) wire as short as
possible on each DC Power Cable, strip
them, and crimp terminal lugs to them.
♦
Drill an appropriately sized hole for the
terminal into the cleared-out chassis location
and de-burr the hole.
♦
Screw all three lugs into the chassis ground.
Separate each lug with star washers and
ensure a reliable metal-to-metal contact.
NOTE
The white wire of
the DC Power Cable is connected
to fused ignition sense of the
vehicle only in the Dash-Mount M803 Radio. It is not necessary to
connect the white wires of the three
DC Power Cables of the V-TAC to
ignition sense. The Control Head
wakes up the V-TAC when power
is applied. However, connection of
the ignition sense for the V-TAC
may be needed in the future in
configurations that do not use the
Control Head (e.g., data-only
applications). It is recommended
that the white wire be coiled and
placed aside rather than cut from
the cable assembly.

17. 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
but not over-stressed.
TESTING
This section sets forth procedures to verify the performance of the installed V-TAC.
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 normal
operating mode of the V-TAC for voice or data communications is OpenSky® Trunking
Protocol (OTP), the radio must be operating in OpenSky® Conventional FM (OCF)
mode for testing. The reason for this is that OTP uses a Time Domain-Multiple Access
(TDMA) protocol in which transmit power is difficult to measure with standard
equipment. Conventional FM mode allows for 100% duty-cycle transmissions. Follow
the procedure under Changing Operating Modes to switch between the OCF and
OTP.
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.
Test Equipment
Comments

Bird Electronic Corporation Model 43 or
equivalent, with N-Series female connectors on
both the input and output sides.
As an alternative to using a wattmeter, a
Voltage Standing Wave Ratio (VSWR) meter,

equivalent, can be used to carry out the
required RF (radio frequency) power testing.

IMPORTANT
This radio has been tested and complies with the FCC RF
exposure limits for Uncontrolled Exposure (General Population)
and Occupational Exposure. 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 safe distance away from a properly installed, externally
mounted antenna.
The antennas listed in Table II have all been approved for use with the V-TAC. Table
III lists the minimum safe distances for approved antenna types.

The M-803 may be mounted in a wide range of vehicles with varying, non-standard
physical dimensions, so selection of an antenna and its location is not trivial. Only
install antennas where a minimum safe distance (MSD) can be maintained in a
measured, visual line of sight from the antenna location to any location where a person
may be located under normal operating conditions. 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 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 preferably mounted 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 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 Some antennas have a feature that allows them to be mounted on
the lip of the trunk lid. 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.

side of the wattmeter, in place of the
antenna cable (see Figure 2).
2.
Apply power to the V-TAC through
the Control Head and switch to
OCF mode, if necessary.
♦ The V-TAC must be operating in OCF
mode in order to continue with the
testing procedure. If the Control Head
does not display “OCF” during startup
indicating that it is initializing in OCF
mode, use the procedure under
Changing Operating Modes above.
3.
Position the slug to measure
forward RF power output.
♦ Rotate the slug, if necessary. The arrow
on the face of the slug must point from
the V-TAC toward the dummy load to
measure forward power.
4.
Measure the RF power output from
the V-TAC.
♦ Key the microphone on the Contro Head
and note the wattmeter reading. De-key
the microphone.
5.
Compare the wattmeter reading
with the target RF power output
range specified in the Notes
column, opposite.

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 specified
frequency range of the V-TAC. 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 RF output signal*.
♦ Use the procedure under Changing
Operating Modes above. The V-TAC is
now ready for normal communications.
The standard measure for comparing forward and reflected power is the Voltage Standing Wave Ratio (VSWR). Use the
values recorded for the installed unit’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.
