Panasonic AJ-D700P - Manual (Page 101)

Replacing the Backup Battery
The unit is shipped from the factory with a backup battery already mounted. When the battery runs
out, the TCG time code value indicates 00:00:00:00.
At this time, the time code value cannot be backed up.
In addition, the “BACK UP BATT EMPTY” display appears in the viewfinder for 3 seconds when
the POWER switch is set to ON to indicate that the battery must be replaced.
Consult your dealer when replacing the battery.
