Page 6: Installation
4.0 INSTALLATION The M760 is very simple to physically install in an aircraft’s instrument panel. Select or cut a 57mm (2 ¼”) instrument hole for mounting. Present the M760 to the rear face of this hole. The stepped round face will insert through the hole, and should appear flush with the front of the instrument panel when correctly positioned. -
Page 7: Electrical Installation
Connect to the rear of the radio with a push fit, and secure the locking bolts (top and bottom). Microair recommends the use of its pre-wired M760 harness. The harness is available from Microair, and comes complete with all switches, sockets, buttons, and mounting hardware. -
Page 8: Coax Termination
ANTENNA For certified aircraft the M760 should only be operated with a TSO compliant antenna. The antenna may be ¼ wave whip or ½ wave dipole, using 50ohm coaxial cable and a BNC connector for connection. The VSWR should ideally be less than 2:1 across the 118.000MHz to 136.975MHz airband. -
Page 9: Power
M760 Transceiver Installation & User Manual POWER The M760 is designed to operate on a 14V aircraft electrical supply. The radio will operate down to 10.7V on receive. It is unlikely that a power supply operating below 11V would have sufficient power to allow clear transmissions. -
Page 10: Microphone
When the PTT is pressed both microphones are live. To reduce background noise, the M760 can be installed with relays across the mic lines and the PTT line, to allow only one microphone at a time to operate. -
Page 11: Internal Vox Intercom
Installation & User Manual INTERNAL VOX INTERCOM The M760 is fitted with a VOX intercom feature which utilises the sidetone facility of the radio. The VOX threshold level is controlled in software by use of the Intercom Adjust Mode. See section 5.4 to adjust the internal VOX intercom. -
Page 12: External Intercom
DUAL COMM INSTALLATION Where two M760’s are to be installed in the aircraft, the interlock lines must be installed. Each interlock line shall be wired from (pin 4) on the first radio to (pin 7) on the second radio, and vice versa. -

Page 16: Toggle Switch
The M760 will not transmit if the active frequency or selected memory channel is below 118MHz. The M760 will not transmit if the CD lockout function is enabled and the M760 is currently receiving a signal. See section 6.1 to enable / disable the CD lockout function. -

Page 18: Monitor Function
NOT monitored. While receiving a signal on the standby frequency the active channel is periodically monitored. If a signal is found on the active frequency the M760 will revert to the active frequency. After a signal has been received the M760 will return to monitoring both frequencies. -
Page 19: Channel Mode
Installation & User Manual CHANNEL MODE The M760 has memory database which can store up to 99 channels. Each channel can be programmed with any available frequency from 108.000 to 136.975MHz, and an 8 character channel name. Refer to the PROGRAM MODE Menu (sections 7.4 & 7.5) for details on the programming of memories. -
