TROUBLESHOOTING
TROUBLESHOOTING
Having trouble getting things to “cooper-
ate”? Consult the Troubleshooting chart on this
page. It should point you in the general direc-
tion of things to check, etc. Then proceed to
the following pages to help you narrow down
the problem. If you believe the problem is HUI
related, see the Service section on page 27.
Perform a HUI Hardware Self-Test
HUI has a built-in self-test routine which
can help you determine if the problem you’re
experiencing is HUI related or not. You need
the following items to perform the self-test:
• One standard MIDI cable
• Two normally-open footswitches (or two
1/4” plugs or patch cords with tip
shorted to sleeve)
1. Connect a MIDI cable from
HUI’s
MIDI OUT
jack to HUI’s
MIDI
IN
jack. This allows HUI to run the
test and then loop the information
back to itself.
2. Connect a normally-open foot-
switch to each of the
FOOTSWITCH
IN
jacks.
3. Plug the power cord into a 3-
prong AC outlet, that you know has a
good safety ground. (You might want
to test the outlet with an AC outlet
tester. You can get one at Radio Shack
or most hardware stores.)
4. Turn on HUI by pressing the
POWER
switch on the rear panel.
5. Within three seconds after turn-
ing on the power, simultaneously
press the
SHIFT
and
OPTION
but-
tons (located in the “Keyboard
Shortcuts” section at the lower left
area of HUI’s front panel). You will
see the 40x2 character VFD on the
front panel light up and it will prompt
you with the instructions to complete
the self-test.
Note: You can quit the self-test at
any time by simply turning off HUI’s
Power switch.
Be sure to follow the instructions
displayed in the VFD completely. You
want to be sure HUI is ready to roll
when you’ve finished this test.
6. Use the footswitch to step
through the self-test. By now you
may be thinking, “Why is it called a
‘self-test’ when I have to help it
along?” It’s because we thought
“Human-Assisted Semi-Self-Test”
was practically an oxymoron, not to
mention being a bit long.
Audio
If you’re having trouble getting audio through
HUI, check the following:
General
• Say, uhhh, is the
POWER
switch turned on?
Sorry—gotta ask.
• Have you tried re-booting HUI by turning it
off, waiting a few seconds, and then turning
it back on again? Sometimes this can help
alleviate the little burps and hiccups that
can occur. (Be sure to turn down the volume
on any connected power amps first BEFORE
re-booting.)
