Ensure the VEHICLE MASTER POWER switch and the DVE POWER switch are set to ON. 2. The time necessary for the system electronics to stabilize depends on ambient temperature. As ambient temperature rises or cools, the stabilizing time changes slightly. 3. The words “...NO-VIDEO...” will appear within a black rectangle at the top center of the display only if the VIDEO switch is in the EXT position or the display circuitry has no video input. The display circuitry senses the presence of video. If the video is absent during operation, the words “...NO-VIDEO...” are indicated. If the video returns, the words are removed, but the no video indicator bar remains to indicate an intermittent loss of video. The no video indicator bar is cleared from the display by recycling the power switch (power OFF and ON). 4. Set POWER switch to ON (up position). The power light-emitting diode (LED) will illuminate. Allow five minutes for system electronics to stabilize for maximum image clarity. NOTE When the VIDEO switch is in the EXT position, the “... NO VIDEO...” message will appear until an external video input is supplied to the DVE. 5. Leave the VIDEO switch in the SENSOR (up position) for sensing input from the sensor to the display. For external input to the display, set switch to EXT (down position). 6. Adjust the seat height and/or Display Module to place the display at eye level. Loosen the two display adjustment knobs on both sides of the Display Module. Adjust the tilt of the Display Module either up or down. Retighten the adjustment knobs. 0035 02-3 Change 1
