Beware of fabric surfaces with silver dope finishes. The silver dope is a conductive surface, and will
screen antennas which are mounted internally. Refer to the Microair Avionics website
www.microair.com.au for more detail on antennas suitable for non-metal skin aircraft.
2.13.3 Antenna Location
For best results while in Split Mode, we recommend that the one VHF communications antenna is located
on top of the aircraft while the other communications antenna is installed on the bottom. Any antenna
relocation must be accomplished in accordance with AC 43.13-2B, aircraft manufacturers’ recommenda-
tions, and other FAA-approved technical data.
WARNING
It is probable that radio interference will occur in the split mode when the frequencies of the two air-
craft radios are adjacent, and/or the antennas are physically close together. PS Engineering makes
no expressed or implied warranties regarding the suitability of the PAR100EX in Split Mode.

The microphone gain and sidetone are adjustable via the trim pot(s) which can be accessed
