Section 2 Installation

2.1 General Information
The PM1000II comes with all necessary hardware for
installation.
Installation of the PM1000II, using the available wir-
ing and hardware supplied, does not require special
tools or knowledge other than described in FAA Advi-
sory Circular 43.13-2B. It is the installer's responsibil-
ity to determine the approval basis for this installation.
An FAA From 337, or other approval may be required.
See Appendix B for example of FAA Form 337.
2.2 Unpacking and inspection
The PM1000II was carefully inspected mechanically
and thoroughly tested electronically before shipment.
It should be free of electrical or cosmetic defect. Upon
receipt, verify that the parts kit includes the following:

2.3 Equipment installation proce-
dures
1.Using the template, drill six holes in the instrument
panel in a location convenient to the pilot position.
2.Insert the PM1000II from behind the instrument
panel, aligning the holes for the knobs, LED, and
switch.
3.Place the aluminum face-plate over the knob shafts
and secure, using the two # 4-40 round head
screws provided.

4.Install the knobs over the volume and squelch con-
trol shafts.
Note, an optional mounting plate for 2¼" round instru-
ment hole is available. See page 7.
2.4 Cable harness wiring
To complete the installation, a wire harness must be
made as shown in Appendix D.
PS Engineering can make a custom-tailored wiring
harness for the installer. All harnesses use Mil-spec
quality components with professional techniques, and
are fully tested before shipment.

2.4.1 Electrical Noise Issues
WARNING: You must use separate shielded cables
for the microphone and headphone jacks. Combining
these two wires WILL cause loud oscillations and de-
grade the intercom function. The oscillation is caused
by the cross-coupling between the large headphone
signal and the small microphone signal. The resulting
