Note: If using the optional hands-free visor microphone, mount
the speaker at least 5 feet (1.74m) from, and not in line with,
the microphone. Mounting the speaker on the dashboard or
rear package tray is not recommended. For optimum radio
performance, install the speaker under the dashboard.
When possible, mount the RFPA as close as practical to the external
antenna, in a location that does not restrict air flow through the
cooling fins. The RFPA is typically mounted in the vehicle's trunk.
Complete mounting instructions are supplied with each RFPA kit.
Refer to those instructions for information pertaining to the RFPA.
Refer to the console's "Battery Connections" section above for RFPA
power cable routing recommendations. A 17' (6.02m) coaxial cable
with a mini-UHF connector on one end is also supplied with the RFPA.
This cable must be routed from the console to the RFPA. The mini-UHF
connector attaches to the PA. The cable should be cut to the
appropriate length and the supplied mini-UHF or BNC connector
attached.
Referring to Figure 1, install the console using the following procedure,
or modify the procedure as necessary to conform to the vehicle type.
Using the optional trunnion ("U") bracket as a template, drill the
mounting holes and mount the bracket with the hardware supplied
(see Figure 1).
Note: Failure to use the four outermost holes on the trunnion
bracket, or mounting the bracket on a non-flat surface (such
as a transmission hump) could degrade vibration
performance. Additionally, the VA trunnion bracket should
be mounted on a metal surface.
Note: When the bracket is mounted in carpet, the self-tapping
screws tend to bind up. To overcome this, tap the screw
through the carpet, back out the screw, then tighten the
screw down.
1. Remove the Allen-head screws from the side of the console.
Important Note: To avoid permanent damage to the unit, if
mounting the console in a customer-provided bracket, ensure
that the Allen-head screw shaft protrudes into the console's
chassis no more than 17/32" (1.35cm) and no less than 1/2"
(1.27cm).
2. Ensure that the plastic guides of the trunnion are aligned
(horizontally) with the corresponding grooves of the console (see
Figure 1). Slide the XTVA console into the plastic guides until it
reaches the mechanical stop. Verify that the holes in the
trunnion bracket are aligned with the holes on the XTVA chassis.
3. Insert the Allen-head screws provided through the trunnion
bracket and screw them into the console. Since the console may
have to be removed later to connect the cables, do not tighten the
screws at this time.
