Replacing the Backup Battery
The backup battery is installed before the unit is shipped from the manufacturing plant.
When the battery is totally discharged, the “E-90” error code appears for 3 seconds in the status
display window when the POWER switch is set to ON.
“00 : 00 : 00 : 00” is displayed as the TCG time code value, indicating that the time code can no
longer be backed up. In this situation, the backup battery must be replaced.
Consult your dealer, and replace with a new battery (CR2032 or BR2032).
