The Microair 760 was designed for use in aircraft requiring compact size with low power consumption and yet it retains many features not found in competitor's products.
With a face diameter of 2¼" (57mm), its size makes it ideal for cramped panel designs and its very short length beneficial for aircraft which lack depth behind the panel.

The Microair 760 transceiver is compatible with a variety of microphone and speaker combinations including all general aviation microphones. It has been proven to function satisfactorily in high noise environments.

The unique LED multifunction annunciator located at the top right of the transceiver provides the following alerts:
 

Receive no incoming signal - Squelched with no signal present LED is clear

Receive incoming signal - Squelch broken with signal being received LED is green

Transmitter on - LED is red

Transmitter on longer that 40 seconds - LED blinks RED

The blinking RED LED is designed to advise pilots when they have a stuck PTT button. An external memory toggle switch can be installed which allows the remote selection of twenty five memory frequencies, with memory channel 25 dedicated as an emergency frequency and accessible with one press of a button.

The Microair 760 Transceiver can be wired to take advantage of an internal side tone intercom with either 'Press to Talk' or hot mic options and an optional Pilot Priority over-ride. The Pilot Priority over-ride has been designed for instructor/student environments to allow the instructor to over-ride a student's transmission should he be making errors.
