Level operation:The function is operational while the pin to which it has
been allocated is shorted to ground.
Edge operation:The function is operational when the pin to which it has
been allocated changes from open to shorted to ground.

If a function whose operation condition is triggered by the level has been
allocated to a multiple number of pins, it will continue to be operational
while any one of those pins is shorted.

Error and warning displays
If an error has occurred in the monitor for some reason, an error or warning display will appear on the screen.
± CRCC error
≥ When this error appears
When the SDI signals contain an error, the CRCC error display appears on the screen.
When a menu is displayed, the error is indicated in the menu area.  At all other times, it is indicated on the status
display.  However, only the error will be displayed when 3SEC OFF or OFF has been selected as the STATUS
DISPLAY item setting on the OSD screen.  On the other hand, if OFF has been selected as the CRCC MESSAGE
item setting on the OSD screen, the error will not be displayed even when it has been detected.
≥ Countermeasure
Check the input signals and connection statuses.
± Inverter error
≥ When this error appears
If trouble has occurred in the inverter which controls the brightness of the backlight, the backlight is turned off, and all
the lamps by the sides of the image controls and tally lamps flash at 1-second intervals.
≥ Countermeasure
Turn off the power and turn it back on.  If the error display persists, contact a Panasonic Service Center.
± Low remaining battery charge warning/error
≥ When this warning/error appears
If the battery voltage is 10.5V to 11.3V:
(If the remaining charge is less than 10% when an Anton Bauer digital battery is being used)
>The remaining battery charge and voltage are displayed on the screen, and the display flashes.
If the battery voltage is less than 10.5V:
>“END BATTERY” appears on screen in red for about three seconds, and the power is turned off.
≥ Countermeasure
Replace the battery with one containing a sufficient charge.

Maintenance and inspections
≥Wipe off any dust or dirt on the monitor and LCD panel with a soft cloth.
For stubborn dirt or stains, wipe the monitor and LCD panel with a cloth that has been lightly dampened with well-diluted
kitchen detergent and wrung out thoroughly, then finish it off with a dry cloth.  The monitor may malfunction if even one
drop of water gets into the internals.
≥Do not use benzine, paint thinners, etc. to clean the monitor.
They may discolor the monitor’s surfaces or cause the paint to peel off.
≥Do not spray detergent or other cleaners directly on the monitor or LCD panel.
The monitor may malfunction if even one drop of water gets into the internals.
In order to ensure that this video component will provide many hours of trouble-free operation, provide the appropriate
maintenance and servicing at periodic intervals so that the monitor’s functions will be kept in perfect working order at all
times.  In order to ensure that the monitor’s functions will perform to the best of their ability for a long time to come, be
absolutely sure to conduct the maintenance and inspections described here.
1. Necessity for periodic maintenance and
servicing
A backlight power supply is used in this LCD monitor.
This part (which is a consumable) will deteriorate over
time and lead to a reduced level of performance and
failure.
For this reason, do not confine the maintenance activities
to the kind of after-sale servicing which is performed when
the usual failures have occurred.  The user should know
that it is important to follow through with comprehensive
servicing which involves periodic maintenance and
servicing aimed at keeping up the performance that the
monitor is designed to provide and preventing sudden
failures caused by consumable parts, etc.
2.Maintenance timeframe and implementation
item
The maintenance implementation time given below is
provided as a standard guideline, and it does not
represent the service life of the part concerned.  It should
also be borne in mind that the period over which the part’s
performance will deteriorate differs according to the
operating environment and method.
Part Quantity
BacklightPeriodic maintenance/inspection and time (hours)
Replace every 38,000 hours. 1
