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 dis-
play.
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 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
TY91/92(L) Radio power (as COM 1 only)
The power supply for the TY91/92 communication transceiver is separate from the audio panel power and
control. When the TY91/92 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, TY91/92(L) as COM 2
If the Trig TY91/92 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 COM radio.
