External Hard Disk Drives
The system can have additional hard disk drive upgrade of
one 500 GB external hard disk drive, one 1 TB external hard
disk drive and two 2 TB external hard disk drives (you
cannot combine different capacities of hard disk drives).
Follow the procedure below to format the hard disk.
1 Press the [OPERATE] button for two or more
seconds to set operation to off mode.
2 Switch off the power switch on the rear panel.
Make sure the power switch turned off.
3 Connect the external hard disk drive to the
[SERIAL] port on the rear panel, then switch
on the power.
Make sure the power to the external hard disk drive has
been switched on before switching on the VR-N900U. The
system will not recognize the external drive unless it has
been switched on beforehand.
4 Switch on the power to the VR-N900U.
• If the new hard disk drive is detected during recording,
confirmation window will appear asking whether you want
to stop recording and format the hard disk.
Click the [OK] button to automatically start up the HDD
Utility. ( Page 69)
A confirmation window will appear only during recording.
5 Check the entry in the Volume field, then click
the [Format] button.
The external hard disk drive will be formatted.
Check that [unformat disk], [unpartition disk] or [unknown
partition] appear in the volume field. Selecting any other
volume will result in the deletion of recorded data.
CAUTION
• Consult your nearest JVC dealer for details on the
external hard disk drives that can be used.
• When the additional hard disk is connected, the recorded
image of over ten seconds may be lost at the time of
archiving.
• Note that simultaneous playback of video recorded on an
external hard disk drive on the VR-N900 and multiple
clients will slow down playback of audio and video. This is
normal and not a fault of the recording. Normal playback
will be restored when simultaneous playback ends or the
number of devices involved drops.
Note
• It is recommended that a UPS is used to ensure stable
operation of the system.
• It is impossible to disconnect an external hard disk from
the VR-N900U and connect it to a personal computer to
view the recorded images.
