Ultrasonics don’t work.
Check ultrasonic holes on bottom of
receiver for m
ud or debris. If dirty,
carefully clean them out. Be extremely
careful not to puncture the metal inside the
ultrasonic holes. Use isopropyl alcohol
(99% by volume) in modest amounts;
swish around (upside down) and fling out
the liquid. Repeat two more times and
allow to dry for about 15 minutes.
If you still cannot get the ultrasonic
function to pe
rform properly, call DCI
customer service at 425-251-0559 or 800-
288-3610 for assistance.
