Bluetooth® Telephone Mode
The PAC45J serves as a full duplex interface for telephone systems such as
portable cellular phones with Bluetooth connectivity.
Warning: United States FCC Regulations contained in 47 CFR § 22.925
currently contain prohibition on airborne operation of cellular telephones.
"Cellular telephones installed in or carried aboard airplanes, balloons or
any other type of aircraft must not be operated while such aircraft are air-
borne (not touching the ground). When any aircraft leaves the ground, all
cellular telephones on board that aircraft must be turned off."
Answering or placing a call is done from the mobile phone. Once connect-
ed, the audio is routed through the headset(s) by ushing the TEL button0.
For a single Control Head installation:
In ALL intercom mode, all crew and passengers will be heard on the
phone when they speak.
In CREW mode, the pilot and copilot are connected to the telephone.
In ISO intercom mode, when the PAC45J 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.
For multiple Control head installations:
Each user's CTL45A controls their access to the telephone audio.
NOTE
PS Engineering does not guarantee compatibility with personal cellular
telephones.
Bluetooth Reset
If the Bluetooth stops connecting to a device, or operates incorrect-
ly first try turning Bluetooth off, and back on from your device. If
also me be necessary to reset the Bluetooth module, clearing out
the connected devices. Press HRTF and ICS for more than
three seconds. Then "forget" the PAC45J on the phone,
and re-pair.
This may be necessary if the Bluetooth stops connecting to a device, or
operated incorrectly.
Music Muting Control (10)
The PAC45J incorporates PS Engineering's trademark "SoftMute. The
SoftMute™ circuit will mute the music whenever there is conversation on
the radio or the intercom. When that conversation stops, the music returns
to the previous level comfortably, over a second or so.
