Auto diagnosis feature
This receiver incorporates a new auto-diagnosis
feature. With this new feature will be easier for the
technicial 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 detected by 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 Table 3.
Please use this feature effectively especially for
intermittent problems.
Table 3: SOS of front LED
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.
