TROUBLESHOOTING GUIDE

8

We have carefully tested and have found no
problems in the supplied 

MT108-104/(105)

;

however, we would like to offer suggestions for the
following:

 

8.1 LED IS NOT LIT

 

8.2 NO SOUND

 8.3 SOUND DISTORTION

 8.4 SOUND LEVEL IS LOW

8.1  LED IS NOT LIT

Cause 1:

Card cage is not plugged in.

Solution:

Plug card cage in. If the LED lights,
the problem is solved. If the LED is
still not lit, 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 lights,
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.

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
