Handling Precautions
O This unit has been designed with foremost
emphasis placed on its reliability as a transmission
server. However, to prevent accidents in
transmission due to breakdown or obstructions, it is
requested that the server be used with a system
compiled in duplicate.
O By having a newly-developed RAID device built in,
the system is designed for continuous operation
even if one HDD (hard disk drive) unit breaks down.
However, to avoid secondary complications, if one
HDD unit breaks down, terminate operation
immediately and request servicing from your dealer.
O The system is designed so that a faulty HDD can
be replaced even while continuity is maintained, but
normal operation thereafter cannot be guaranteed.
Do not replace a HDD during recording or playback.
O The system is designed to facilitate data restoration
by replacing a faulty HDD with a new one, but
backup copies of data on recording tape, etc.,
should be made so that
recorded on the HDD are not lost due to equipment
problems, etc.
Faulty equipment can be serviced by your dealer
but lost contents cannot be restored.
O Do not execute recording or playback while data is
being rebuilt.
If recording or playback is not being executed, the
system disk (9GB) can be rebuilt in approximately
10 minutes and data disks (36GB) can be rebuilt in
about 1 hour.
O Do not use this unit in a vehicle.
This may cause injury or result in problems with the
hard disk drive or data.
O It takes about 3 seconds to switch to REC mode
when the REC command is sent in REC CUEUP
mode.
O When an HDD is loaded onto this system, extra
weight is added to the front panel side. Please note
this fact and exercise due caution when moving the
system.
O Whenever a problem occurs with POWER A or
POWER B in the power supply unit, be sure to
always turn the relevant power supply switch to
OFF.

$ Precautions for video and audio input/output
operations
O For input/output of HD signal from VTR to the
server, use a codex unit that is compatible with the
server.
O Use the AJ-D780 when using the SDTI 4a speed
for input/output from a VTR to the server.
O When using the SDTI 1a speed for input/output
from a VTR to the server, use a VTR mounted with
SDTI baseboard such as AJ-D850, AJ-D950 or AJ-
D960.
The AJ-D780 does not have a SDTI 1a speed
function.
O When using analog or SDI input/output, signals
buried in the video blanking area (e.g., signals for
letter broadcasting) cannot be recorded or played
back.
Recording and playback are possible when a SDTI
I/O board is used.
