SOLUTION
Re-adjust soundhead azimuth and reset
preamp levels and high frequency boost with
test fi lm.
Make sure the soundhead guide rollers are
not loose and do not have any end play.
Some rollers are spring-loaded on one side.
Make sure the fi xed side is not loose.
Surround levels are set too high. Reset SPL
levels.
The solar cell is too far back. Move it to within
.040" (1 mm) of the fi lm and readjust.
Lift power ground on Computer power pack
or run computer on battery power.
When the Word Clock is missing on the
Left/Right channel pair, the front LED will
fl ash, indicating a fault of the external device.
It will also fl ash if there is no external device
connected to EXT 2. Check the wiring and
functionality of the external device.
Make a note of the numbers that appear
in the main fader display. Put the unit into
BYPASS to prevent possible loudspeaker
damage. The fl ashing LEDs mean that
software corruption has been detected. A
"91," "92," or "93" is a software fault in the
Input Module (JSDA80). A "61," "62," or
"63" is a software fault in the Output Module
(JSDO80). Have the technician replace the
defective module and follow the System
Restore in Section 10.4.
