This section provides detailed operating instructions for the PS Engineering
PAR100EX, Audio Selector Panel/Intercom/VHF Communication Control
Systems. Please read it carefully before using the equipment so that you can
take full advantage of its capabilities.
This section is divided into sections covering the basic operating areas of the
PAR100EX systems. They are Communications Transceiver Selection, Audio Selector, Intercom, VHF COM, entertainment, telephone, and display.
Power and Fail Safe (1)
Unit power is turned on and off by pushing the volume (left) knob. In the
OFF or "EMG" position, the pilot headset is connected directly to Com 1 as
well as unswitched input #1. This allows communication capability regardless of unit condition. Any time power is removed or turned
selector portion will revert to fail-safe mode.
The power switch controls all audio selector panel functions and the intercom. All pushbutton selections and menu modes (except Bluetooth telephone
association) will be remembered and return to the last state when turned on.
OFF, the audio
Radio power (as COM 1)
The power supply for the remote communication transceiver is separate from
the audio panel power and control. When the M760 is installed as COM 1, or
as a stand-alone COM, it can be controlled separately in the event of a problem in the audio panel portion, or audio panel power.
If the audio panel is turned off by the left knob (or the audio panel breaker is
opened), the display will indicate “Push radio knob within 6 (countdown)
seconds to keep radio on” If the knob is not pushed, the com radio will also
turn off, but if the data knob is pushed within, the radiofrequency display,
volume and frequency control will remain active.
Communications Transmit (XMT) Selection (2)
The two buttons C1 and C2 (# 2) in the XMT section control which commu-
Page 2 202-760-0100 PAR100EX Pilot Guide
nications radio is selected for transmit. The top row of pushbuttons (# 3)
allows selection of the receiver audio. Push the lower button to select the
desired COM transmitter. A green LED above the button illuminates to indicate that the audio is selected.
The PAR100EX-Series has an automatic com receiver selector system. Audio from the selected transceiver is automatically heard in the headsets and
speaker (if selected). You can check this function by switching from Com 1
transmitter to Com 2 transmitter by pressing the C
OM 2 transmitter selector
pushbutton. See that the associated Com 2 receive pushbutton indicator light
that is located immediately above the Com 2 transmitter pushbutton turns
green. This guarantees that the pilot will always hear the audio from the
transceiver selected for transmit.
The PAR100EX “remembers” the receiver selection, so that when switching
transmitters from C
OM 1 to COM 2, if COM 2 audio was previously selected,
COM 1 audio will continue to be heard. This eliminates the pilot having to
switch Com 1 audio back on, after changing transmitters.
When switching from C
OM 1 to COM 2 while Com 2 was not previously se-
lected, COM 1 audio will be switched off. In essence, switching the mic selector will not override prior selection of COM
receiver audio.
In normal (not split) modes, the PAR100EX
gives priority to the pilot’s radio Push-To-Talk
(PTT). If the copilot it transmitting, and the
pilot presses his PTT, the pilot’s microphone
will be heard over the selected com transmitter.
Split Mode
The split mode can be activated at any time by
pressing the C1 and C2 XMT
buttons at the same
time. This places the pilot on COM 1 and the Copilot
on COM 2.
Pilot on C
OM 2 and Copilot on COM 1 is not possible.
NOTE
Due to the nature of VHF communications signals, and the size constraints
in general aviation aircraft, it is probable that there will be some bleed-over
in the Split mode, particularly on adjacent frequencies. PS Engineering
makes no warranty about the suitability of Split Mode in all aircraft
conditions.
Swap Mode (Switch from Com 1 to Com 2 remotely)
With a yoke mounted, normally open momentary switch, the pilot can
change from the current Com transceiver to the other by depressing this
switch. To cancel "Swap Mode," the pilot may either press the yoke mounted
switch again, or select a different Com with the XMT buttons.

COM Audio Selector (3)
Communication audio from the other radio, not selected for transmit, can be
heard by pressing the associated RCV button. You will always hear the audio from the selected transceiver.
In SPLIT mode, only the pilot will hear selected navigation audio (A1 &
A2).
Navaid Audio selection (4)
VHF Navigation receiver audio is selected through two momentary, pushbutton, backlit switches.
The users can identify which receivers are selected by noting which green
LEDs are lit above the button. Navigation aid audio push buttons are labeled
A1, A2.
Any other installed receiver audio (Marker, ADF, etc) is interfaced through
an unswitched input.
VHF Transceiver control (5)
The right side of the PAR100EX is dedicated to control of the VHF communications transceiver. Frequency selection is always directed to the
STANDBY side of the display.
Frequency Selection (6)
Turn the large (outer) knob to change the frequency whole MHz, and the
smaller, inner knob to change the .100 MHz frequency.
Push the small knob momentarily to transfer standby frequency to the active
frequency.
Push momentarily
Radio Volume and Radio Squelch (7)
To change the radio volume, or defeat the automatic radio squelch, push and
hold the frequency-select knob for one second, until the display changes to
the volume and squelch menu.
Turn the large knob to decrease the radio squelch (to listen for weak signals),
and the small knob to adjust the radio receive audio level. You can push the
knob again to return to the frequency display, or the display will revert automatically after five seconds without any activity.
