2.6 Communications Antenna Installation Notes
For best results while in Dual installations or Split Mode (two communicates transceivers active at the same time),
we recommend that the one VHF communications antenna is located on top of the aircraft while the other communi-
cations antenna is installed on the bottom. Any antenna relocation must be accomplished in accordance with AC
43.13-2A, aircraft manufacturers’ recommendations and FAA-approved technical data.
Warning:
It is probable that radio interference will occur in the split mode when the frequencies of the two aircraft radios
are adjacent, and/or the antennas are physically close together. PS Engineering makes no expressed or implied
warranties regarding the suitability of the PAC24 in Dual or Split Mode.
2.7 Telecommunications interface
The PAC24 has interface capability with some cellular telephone systems (visit www.ps-engneering.com/support for
details). It is the user’s responsibility to determine the appropriate legal use of the equipment, and provide the equip-
ment and services.
As installed in the standard configuration, the PAC24 Com 5 function operates conventionally. Pushing the Com 5
Xmt button places the receive audio from Com 5 in the headset and applies the pilot or copilot microphone to the
Com 5 when the appropriate PTT is activated.
If telephone mode is selected by the internal DIP switch, (S4 Switch 4, see §2.3.2.9) the PAC24 is forced into Com 5-
Duplex mode. This mode is designed to operate with telecommunications systems. Intercom Audio streams are pro-
vided to the COM 5 output, the PTT for Com 5 is inactive, and audio from Com 5 is presented to the headset. This
allows a telephone-like audio interface. The COM 5 input and output is compatible with aviation radios.
In a DUAL Audio Panel installation, the telephone mic audio input should be connected to the both audio panels
COM 5 Mic output (J3 pin only).
PS Engineering makes no expressed or implied warranty that the equipment will be compatible with any devices. For

Unauthorized use of cellular telephone devices in aircraft is subject to FCC enforcement action,
which may include a $10,000 fine per incident. PS Engineering, Inc. does not endorse using unap-
proved cellular telephone equipment in flight, and takes no responsibility for the user’s action.
