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
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.
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.
