 Sufficient speech volume is very important. While the lips are very close and facing the
microphone, speak loud and clear. Proper speech level is indicated by the yellow
flickering LED on the FSG 2T front panel.
 In aircraft / vehicles a suitable noise canceling microphone or headset shall be used.
 A backup microphone should always be carried during any flight. Even new
microphones can fail!
 Prior to any flight verify proper FSG 2T functions by means of a short radio check. It has
however to be taken into account that with a faulty antenna or its cable this COM test
may absolutely turn out positive at the airfield or in short distance to the ground station.
But at a distance of 2 to 6 miles, a faulty antenna and / or cables will cause
communication breakdown!
 Push-to-Talk keys may stick occasionally.
The transmission signaling RED or flickering YELLOW LED shall be turn to CLEAR or
GREEN when releasing the PTT key.
However, after more than two minutes continuous transmitting (by stuck button or
operator caused), the built-in transmit time-out-timer disables the transmitter in order to
avoid continuous channel blocking. A continuously flashing display warns the user.
