3.4 All Clear
When the sounder picture appears to be abnormal, execute the “all clear” function from the
ETR-30N to try to restore normal operation. All clear erases all transducer settings, so
reenter them referring to paragraph 2.2.
1. Turn off the ETR-30N.
2. Remove the cover.
3. Short between #5 and #6 of J9 on the CPU Board and then turn on the power.
