MPI USER INFORMATION
(Mobile Phone Interface)
 

READ THIS FIRST, NOT LAST

 CONNECTIONS

The interface connects between the helmet and the intercom.

1.   Plug the helmet into the MPI socket.

2.   Plug the short extension ¼” jack (6.35mm) into the intercom.
It will work in either P1 or P2 socket (see15)

3.   Plug the 3.5mm jack into the phone’s hands-free/music socket.

 SELECTOR SWITCH

The switch on the case is a selector switch. It switches the helmet’s mike and speakers to either the intercom or the phone.  It is cybernetically sensible:

4.   Toggle towards the intercom cable and you are with your passenger and radio.

5.   Toggle towards the phone cable and you are with your phone.

 OPERATION

6.   With the switch towards the intercom cable (normal use) you will be able to communicate with the other pilot and the radio.

7.   If the phone rings you will hear it via the intercom.

8.   In order to answer the call you must switch towards the phone cable, and then operate the phone as normal.

9.   You will not hear your own side tone during the phone call because you are not speaking through the intercom

10.  At the end of the phone call end the call on the phone as normal and then switch back to the intercom.

 POINTS TO NOTE

11.  During the phone conversation you will not hear your passenger or the radio. Your passenger will still be able to hear the radio if a call comes in.

12.  During the phone operation your passenger will hear the incoming side but not your side of the conversation. If you want total privacy with a passenger present either pull the P2 helmet jack a little, or ask P2 to turn his speakers to OFF. (helmet volume control fully anti clock-wise)

13.  During normal intercom/radio operation any audio coming from the phone, whether it be the ring tone or caller’s voice or any music that you may have chosen to listen to will be present and will transmit with your voice on the radio if you make a radio call.

14.  Have your phone switched off when making radio calls.
Alternative to switching off, pull the MPI 3.5mm jack during radio work. That way your phone will still log any missed calls or receive messages or data and will not interfere with your radio transmissions.

15. Use the MPI in the P2 socket.  Only P2 will be able to use the phone, however, any phone audio (as in 13) will mute during P1’s radio transmissions and will not be transmitted..
(P2 socket always mutes any audio inputs during P1 transmissions).

IMPORTANT

Listening to music whilst flying will add to
the total sound pressure reaching the pilot’s ears. 
Your brain knows the difference between signal and noise
but your ears don’t.   Keep the volume down.
