TROUBLESHOOTING GUIDE			8

We have carefully tested and have found no problems in the supplied AP445-401. However, we would like to offer suggestions for the following:

8.1NO RESPONSE FROM PANEL Cause 1: The front panel is locked.

Solution: Connect to the AP445-401using standard RS-232 communication. Check the status [STAT] and verify the front panel is “Unlocked”. If there is still no response, please call Altinex at (714)-990-2300.

8.2 NO DISPLAY

Cause 1: The source has a problem.

Solution: Check the source and make sure that there is a signal present and all source connections are correct. If the source is working and there is still no display, see Cause 2.

Cause 2: The correct input is not selected.

Solution: Select the input type from the front panel or RS-232 bus. (See RS-232 accessible commands in Section 7). If no display is present, see Cause 3.

Cause 3: Cable connections are incorrect.

Solution: Make sure that cables are properly connected. Also, make sure that the continuity and wiring are good. If there is still no display present, see Cause 4.
