General Information s pilots, all of us have had to ask Air Traffic Control to “Say Again” at one time or another. Asking ATC to confirm a heading, repeat a squawk code, or reiterate a frequency can make a pilot look like an amateur. -
Page 6: Understanding The Dvr Recorder

Page 9: Recorder Operations
Automatic Recording and Playback The DVR Clock recorder uses a continuous loop which automatically captures all audio going into your headset. When incoming audio stops, so does the recorder. This way, communications are compressed for easy retrieval, and the oldest radio traffic is overwritten. When you want to replay radio traffic, simply hit the Skip button. -

Page 17: Audio Connections
If nothing seems to be happening, check the voltage at Pin 2, using Pin 1 as ground reference. The DVR needs 11 - 32 volts DC to turn on.

Leave all microphone lines alone - they are not needed for any DVR functions. - Page 18 Fig. 2 - Audio Wiring for Mono System (Position ‘C’- page 10) a) Typical Audio Wiring before DVR Installation b) Audio Wiring Needed for DVR Recorder As mentioned earlier, the DVR needs to go in series with the headset audio, much like an in-line filter. The most straightforward way to do this is to disconnect the wire already at the tip connector of the pilot’s head- phone jack and connect it to DVR Pin 14.
