A circuit breaker protects the power going to the D600 Timecode Reader Head (through the 9-pin
connector) against short circuits. The breaker is self-resetting so replacement is unnecessary.
The 9-pin connector (accessed on the XD20 rear panel) is used to connect the timecode cable to the
Timecode Reader on the projector.
Power Supply
This unit supplies power to the XD20. This supply is switchable between 110 VAC and 220 VAC and
adjusts automatically.
The cooling fan in the power supply should be rotating when the power switch on the front panel is
switched on.
To prevent dirt from being pulled into the interior, do not block the ventilation holes at the side of
the XD20 chassis.
