Overwriting the Hard Disk
Advanced Menu
➝
Disk Overwrite Mode
Use this menu to specify how disk overwrite issues are handled
once the hard disk becomes full. Select one of three options:
•
No Overwrite
(i.e., recording stops when the disk is full). An
on-screen message indicates when the disk is full and the unit
has stopped recording. You must acknowledge the message by
pressing
ENTER
. Note that recording will not continue until
the data is either erased or deleted.
•
Overwrite Once
. Recording always starts at the end of the last recording. The unit overwrites all previously
recorded data, then stops before it overwrites any newly recorded data (from the current record session). When the
end of the disk is reached, the unit displays an on-screen message stating that the disk is full. You must
acknowledge the message by pressing
ENTER
. Note that recording will not continue until
RECORD
is pressed.
•
Continuous Overwrite
. Recording always starts at the end of the last recording. When the disk is full, recording
continues by overwriting the oldest video first. In this mode, the unit never stops recording (note that the LCD
display does not count down the remaining time till the hard disk is full).
