Section III OPERATION
3.1 SCOPE
This section provides detailed operating instructions for the PS Engineering PAR200A, 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.
Figure 3-1 PAR200A Operating controls
The following is divided into sections covering the basic operating areas of the PAR200A systems. They
are Communications Transceiver Selection, Audio Selector, Intercom, VHF COM, music, telephone, and
display.
3.2 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 capabil-
ity regardless of unit condition. Any time power is removed or turned
OFF , the audio 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.
3.2.1 TY91(L) Radio power (as COM 1 only)
The power supply for the TY91 communication transceiver is separate from the audio panel power and
control. When the TY91 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 indi-
cate “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 radio display, volume and frequency con-
trol will remain active.
3.2.1.1 Radio Power, TY91(L) as COM 2
If the Trig TY91 is configured as Com 2, it will turn off when the audio panel is off, and the pilot will be
connected directly to Com 1.
3.2.2 ICS and Radio Volume Controls (1)
The inner knob (ICS) controls the volume of the intercom audio. It does not affect the radio, telephone, or
music volume.
The outer knob (RAD) controls the volume of the TY91L COM radio.
