If the expansion unit’s disk drive malfunctions:
• Check the connection cables, pulling them out and re-inserting them into their sockets.
• Restart the expansion unit, then restart the Digital Video Recorder's power supply.
Note
If the drive is restored by restarting the power, then some of the recorded data may be lost. Copy any nece-
ssary data to another location and initialize the disk.
• If the error persists even after restarting the power, then initialize the disk.
Note
Initializing the disk will cause all video and other data stored on it to be erased. If any of the data on the disk
is needed, be sure to copy it to another location before initializing the disk.
• If the error persists even after the disk has been initialized, then it is necessary to replace the hard disk
drive. Consult your TOA dealer for more information.
20.3. Video Loss
Video loss occurs when the camera has become disconnected from the camera input terminal. The camera
input number and the date and time at which the video loss has occurred can be confirmed in the error log.
Note
Video loss will not occur for cameras for which Priority recording and Auto-Recoding has been set to "No,"
even if they are disconnected.
20.3.1. If video loss occurs...
• Restore the camera picture to stop the video loss error.
• Restart the power supply to stop the video loss error.
• For the camera for which video loss is occurring, change the recording settings to "No" to stop the video loss
error. Set both Priority recording and Auto-Recoding to "No."
