In
CREW
mode, the pilot and copilot are connected to the telephone. The pilot and copilot will have
transmit capability on the other selected transceiver Com 1 or 2, simply by using their respective PTT
switch.
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 Bluetooth Reset
If the Bluetooth devices have trouble connecting, it may be necessary to reset the Bluetooth Module. The
PMA450 Bluetooth Reset function is accessible from the setup menu.
During the unit boot up process (while the version numbers appear on the screen), hold the lower line select
button until the setup screen appears.
This places the unit into the “User Setup Mode- home screen”, and allows resetting the Bluetooth Module
When
Unpair All
is pushed, the Bluetooth Module is reset and
ALL
Bluetooth devices are erased from the
audio panel, and can then be added back as desired. This is useful in some cases where the unit or operator
lose track of the devices paired, and cannot get them to connect.
Cycle the PMA450 power to exit setup screen.
3.11.2 Bluetooth 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.
