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 Centre.

±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.
