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
communications, and vice versa.
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 PAR200B is in the
TEL
mode, the pilot posi-
tion is in the "Phone Booth." Only the pilot will hear the telephone, and only
he will be heard. He will also have access to Com 1 or 2, and will transmit on
that radio using the PTT. All selected audio is provided to the pilot. Pilot will
not
have telephone sidetone in Isolate mode.

US Federal Communications Commission regulation 47 CFR 22.925 prohibits
the use of 800MHz Cellular handsets in any aircraft that is airborne. Violation
of this rule could result in suspension of service and/or a fine.
Telephone Sidetone
Most cell phones do not provide sidetone (your voice in the headset when
speaking). The PAR200B provides this sidetone from the factory. If your
phone does provide sidetone, and the sound is distorted, pushing the middle
line-select button will turn it off, while on a call. This setting is remembered
Music Muting (9)
There are two SoftMute™ muting circuits. The front panel "Mute" button con-
trols the pilot’s music.
The SoftMute™ circuit will cut the music out whenever there is conversation
on the radio or the intercom, depending on the “Mute” mode selected. When
that conversation stops, the music returns to the previous level comfortably,
over a second or so.
The Pilot’s Music mute functions are controlled through sequential pushes of
the Mute button, with LED indication of the mode selected.

Music 2 Mute Control

mute control for the passengers. If the passengers are listening to the music 2
input, their Karaoke Mode can be activated by an external switch.
