Installation and Operator’s Manual

It isprobable 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 war-

ranties 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 t he 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 provid-

ed 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 a

list of tested devices, visit ps-engineering.com/faq.

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.
