TROUBLESHOOTING GUIDE 8

We have carefully tested and have found no problems in the supplied MT113-102/103; however, we would like to offer suggestions for the following:

8.1 LED IS NOT ON

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 lights, 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 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

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.

8.3 SOUND DISTORTION

Cause 1: The source level is above 1Vp-p.

Solution1: Make sure that the source level is below 1V p-p. If the sound is still distorted, see Solution 2.

Solution 2: Call ALTINEX at (714) 990-2300.

8.4 SOUND LEVEL IS LOW

Cause 1: The volume levels are inappropriate.

Solution 1: Turn up the source volume. If sound level is still low, see Solution 2.

Solution 2: Turn up the destination amplifier volume. If the sound level is still low, see Cause 2.

Cause 2: Poor signal transmission.

Solution: Check the cables for continuity and make sure that connections are wired properly to verify that there is good signal transmission. Note: Test the system by removing the card from between the source and the destination amplifier. If problem persists, call ALTINEX at (714) 990-2300.
