Optional Speaker Location
Select a location for the speaker that will neither be dangerous to the operator
nor damaging to the speaker. A trunnion bracket is provided for mounting the
speaker. The speaker is normally hung under the dash near the right side of
the console, however, the trunnion bracket permits mounting the speaker
against a wall or other vertical surface, if desired.
A location close to the operator, such as on a door pillar, will minimize APX VA
volume adjustments that might otherwise be needed when ambient noise
conditions worsen (such as when a siren is used). This location is also
desirable if the user wishes to keep the volume level outside of the vehicle low
while on patrol.
Note: Mounting the speaker on the dashboard or rear package tray is not
recommended. For optimum radio performance, install the speaker
under the dashboard.
Console Installation
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: 1. The hardware for mounting the bracket to the vehicle is part of the
NTN8940B kit; not part of the NNTN8527A kit.
2. 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.
3. 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. Use the console to trunnion screws from the kit packaging (unit box).
2. Ensure that the plastic guides of the trunnion are aligned (horizontally)
with the corresponding grooves of the console (see
Figure 1). Slide the
APX VA 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 APX VA.
