Connects to the MM005 Powered Radio Interface. This will provide the capability to have a second VHF/ PMR band radio in the aircraft. The standard lead terminates to a twin 3.5 & 2.5mm jack plug. A CT44 adapter can be used to convert this to a single 4 pole 3.5mm Jack plug. To transmit on the second radio press the PTT on the second radio and speak normally into your headset.

Please note the main airband radio has priority over the music, mobile telephone & second radio. If these devices are playing audio then this will mute when the airband has an incoming signal.
