will also have access to the phone, and all four passengers will hear
the conversation.
In ISO intercom mode, when the PAC24 is in the Com 5 mode, the
pilot position 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 se-
lected audio is provided.
Note: Because the cell phone uses an intercom circuit, all sta-
tions on that circuit will lose intercom capability when the cell
phone is in use.
Internal Recorder System (Optional)
The Intercom Recording System (referred to here as the IRS) is a
digital recording system allowing automatic storage and playback of
aircraft radio traffic.
Operating as a continuous loop recorder, (first message received will
be the last heard), the recorder has one minute of recording time or
up to 16 messages. With its own built in VOX circuit, there are no
buttons to press to start recording. The system automatically begins
to record the instant the radio becomes active. Only aircraft radio
audio in pilot’s headset is recorded and only the pilot will hear the
playback audio.
Recorder Operation
Recording is automatic; there is no action required by the pilot. To
play back the last recorded message, simply press the momentary
switch associated with the IRS. Each additional press of the button
will play the preceding recorded message. You must wait for the
message to finish playing before accessing the prior message.
To cancel the playback, press and hold the playback button for two
seconds. The next time the button is pressed, the next earlier mes-
sage will be heard.
Concurrent Messages
When a recorded message is playing there is no recording of incom-
ing messages. Both the playback and the received radio traffic will
be presented to the pilot headset..
