This section provides detailed operating instructions for the PS Engineering PAR200, Audio Selector
Panel/Intercom/VHF Communication Control Systems. Please read it carefully before using the equipment

Figure 3-1 PAR200 Operating controls
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
capability regardless of unit condition. Any time power is removed or turned
OFF , the audio selector por-
tion 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
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 radio display, volume and frequency
control 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 Music Volume Controls (1)
The inner knob (ICS) controls the volume of the intercom audio. It does not affect the radio, telephone, or
music volume.
