In ISO intercom mode, when the PMA450 is in the TEL 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 selected audio is provided.
NOTE
Because the cell phone uses an intercom circuit, all stations on that circuit will lose intercom capability
when the cell phone is in use. Intercom conversations will still be present if the cell phone provides
sidetone, or if the audio panel is modified for telephone sidetone.
PS Engineering does not guarantee compatibility with personal cellular telephones.
3.11.1 Cellular telephone sidetone
Some cell phones do provide sidetone, and when combined with unit sidetone can cause audio distortion. In
PMA450 Telephone sidetone can be enabled or disabled on the Telephone menu when a call is active.
3.12 Internal Recorder and playback
The PMA450 comes equipped with an internal recorder. This digital system stores the last incoming audio
from the radio you have selected for transmit. It can store as many of 8 incoming messages, and up to 45
seconds of audio. The pilot and copilot hear the playback.
Recording is automatic. To play back the last recorded message, press and hold the COM Receive pushbut-
ton associated with the selected radio transmitter for about one (1) second. You can either wait for the mes-
sage to finish playing before accessing the prior message, or cancel the current playback and step back-
ward. To cancel the playback, press and hold the COM receive playback button for two seconds (2). The
next time the button is pressed for one (1) second, the next earlier message will be heard.
The playback
will stop whenever there is more incoming selected com audio, and the message can be replayed
from the beginning by pressing the selected Com Receive button again for 1 second.
