TOP PREVIOUS NEXT
This receiver incorporates a new self diagnosis feature. With this new feature will be easier for the
technician to detect the failures. There is a LED located by the keyboard on the front panel, this LED
will start flashing when a failure is detectedby the circuits located in specific areas, depending on
how many times the LED is flashing, this will tell you what circuit should be checked. Make a count
of flashing and see the table shown below. Please use this feature effectively especially
forintermittent problems.
AFTER THE COUNT
Proceed to check that area, verify what board is the problem located, this way the area to check will
be reduced until the failure is found.
