Intercom Modes (8)
The “
ICS
” pushbutton switch on the left side of the panel provides the selection of
the three intercom modes.
This button cycles through the intercom modes, from left to right, then right to left
as: ISO, ALL CRW and CRW, ALL, ISO. An LED behind the text shows which
mode is currently active.
I
SO
:
The pilot is isolated from the intercom and is connected only to the aircraft
radio system. He will hear the aircraft radio reception (and sidetone during radio transmissions). Copilot will
hear passengers’ intercom and music, while passengers will hear copilot intercom and music. Neither copilot
nor passengers’ stations will hear aircraft radio receptions or pilot transmissions.
When the audio panel is put into the “Split Mode” (pilot on COM 1, copilot on COM 2), the intercom auto-
matically enters the ISO mode to prevent confusion with two intercom conversations. The intercom can be
changed to the CRW or ALL mode if desired.
A
LL
:
All parties will hear the aircraft radio and intercom. Crew and passengers will hear selected music.
During any radio or intercom communications, the music volume automatically decreases. The music volume
increases gradually back to the original level after communications have been completed.
C
REW
: Pilot and copilot are connected on one intercom channel and have exclusive access to the aircraft
radios. They may also listen to Music 1. Passengers can continue to communicate with themselves without
interrupting the Crew and may listen to music as configured.
3.9 Bluetooth operation
3.9.1
Bluetooth Telephone Connection
Before the PAR200A can be used in TELEPHONE mode with a wireless Bluetooth connection, the unit
must be associated with a specific phone.
Activate the “seek device” function on the cell phone, and then enter the access code “
0000
” when the
phone detects the “PAR200A” on the list of available devices.
This process will be necessary for any phone to be used, and only one cell phone can be associated with the
audio panel at a time. If the additional phones are associated with the PAR200A at the same time, only the
first
phone will transfer audio to the panel.
If the Bluetooth connection fails to reconnect, or becomes unreliable for any reason, you can reset all con-
nections by turning off the PAR200A, holding the N1 and N2 buttons down, and turning the unit back on.
This clears out all paired devices.
PS Engineering recommends this clearing process if you are having difficulties interfacing the PAR200A
audio panel to your Bluetooth phone or device.
3.9.2
Telephone (TEL) Operation
When the Bluetooth-enabled phone receives an incoming call, the PAR200A will play a ring tone. Answer
the call from your telephone handset. The PAR200A exits the telephone mode automatically when the cel-
lular phone hangs up.
In TELEPHONE mode, the pilot microphone and headphones are connected to the cell phone. The pilot
PTT will switch the pilot mic to the selected com transceiver, and allow continued aircraft communications
to continue.
The copilot will also be able to transmit on the other selected radio with his PTT as well.
Entering the TEL mode connects the telephone to the users as follows:
In
ALL
intercom mode, all crew and passengers will be heard on the phone when they speak. Com and
other selected radio audio are also heard in the headsets. If the pilot or copilot pushes the radio PTT, their
microphone will be transferred to the selected Com radio. The telephone party will not hear ATC commu-
nications, and vice versa. Passengers will
not
have telephone sidetone and will
not
hear the ringer.
In
CREW
mode, only the pilot and copilot are connected to the telephone. Passengers will not hear the
telephone. The pilot and copilot will also have transmit capability on the other selected transceiver.
In
ISO
intercom mode, when the PAR200A is in the
TEL
mode, the pilot position is in the "Phone Booth."
