TROUBLESHOOTING GUIDE

We have carefully tested and have found no problems in the supplied MT109-102; however, we would like to offer suggestions for the following:

8.1 LED IS NOT ON

Cause 1: Card cage is not plugged into power outlet.

Solution: Plug card cage in. If the LED is ON, the problem is solved. If the LED is still not ON, see Cause 2.

Cause 2: Card is not plugged in all the way.

Solution: Push the card in all the way. If the LED is still not lit, see Cause 3.

Cause 3: Card cage slot has a problem.

Solution 1: Test the card in other slots of the card cage. If the slot was damaged, the card may work in other slots. If other slots work, and the LED is ON, the problem is the card cage slot. The card cage may require service. Call ALTINEX at (714) 990- 2300. If the other slots do not work and the LED is still not lit, see Solution 2.

400-0343-003

Solution 2: Take any other known good card with an LED and verify that the slot used is good by seeing if the other card’s LED lights in that slot. If it lights, then the original card may be the source of the problem. Call ALTINEX at (714) 990-2300.

8.2 NO SOUND

Cause 1: The source has a problem.

Solution Check the	source	and make	sure
that it is working at an appropriate
volume level and all source
connections	are	correct. If	the

source is working and there is still no sound, see Cause 2.

Cause 2: The proper card input may not be selected.

Solution: Select the card input that is used, by RS-232 accessible commands in section 7. If no sound is present, see Cause 3.

Cause 3: Cable	connections	to	the
destination are incorrect.

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

Cause 4: The destination amplifier has a problem.

Solution 1: Make sure that the destination amplifier is powered. If there is still no sound, see Solution 2

Solution 2: Set the volume of the destination amplifier to a reasonable level. If there is still no sound, call ALTINEX at (714) 990-2300.
