1. Replace.
Try each leadwire
independently in each
channel. If there is no
output on either channel
the leadwire is defective
and should be replaced.
If there is output on one
channel only, a component
may have failed. Call the
repair department.
The Hi-Volt application
is available on Channel 1
only.
1. Verify connection is
secure.
2. Turn down the intensity.
Rotate leadwires in
socket 90 degrees. If still
intermittent, replace
leadwire.
3. If still intermittent after
replacing the leadwire,
a component may have
failed. Call the repair
department.
Some programs will seem
intermittent. This is
expected. Refer to section
3.2 in the manual for a
description of the PPR.
