Precautions for use
1. Precautions for handling the unit
This unit is a disc-based equipment and, as such, its
operation is subject to a set of restrictions which are
different from those of conventional VTRs.
Familiarize
yourself with these restrictions before attempting to
operate the unit.
1-1. Installation
Install the unit on a level surface to ensure stable
operation.
In order to prevent the temperature from rising inside
the unit, never cover the ventilation openings at the
sides of the unit or the fan area installed on the rear
panel.
Avoid installing the unit in the following locations.
e Where it will be exposed to sunlight or other strong
light source.
e Where it will be exposed to heavy concentrations of
dust or vibration. Bear in mind that more dust tends
to be sucked into the unit if it is installed at the very
bottom of the rack.
e Where there are strong electrical or magnetic fields
e Where there are sudden and extreme changes in
the temperature
è Where the surface is slanted (at an angle of over 5
degrees)
è Where there is a heat source or humidifier nearby
1-2. Precautions when using the unit
Bear in mind the following points when operating the
unit.
è Be absolutely sure to use the DVD-RAM
discs
designated,
DVD-RAM discs
e LM-DA52U and LM-DA26U or their equivalent
è Do not leave the tray extended. Dust may find its
way inside and cause trouble.
EK
è Do not use cracked discs or discs which were once
warped and have been bent back.
The disc may
break up into pieces and scatter and possibly cause
injury.
e Do not extend or retract the tray with the shutter
held down.
Do not forcibly extend or retract the
tray.
e While the unit is in operation, do not pry the shutter
open or insert your fingers, etc. into it.
1-3. Concerning vibration and impact
during operation
Recording or playback may be interrupted if the unit is
subjected to external vibration or impact while it is
operating.
If it has been subjected to vibration or
impact during recording, the data already recorded
may be destroyed or it may not be recorded properly.
To prevent accidents like this, install the unitin a
stable
location where
it will not be subjected to
vibration or impact.
1-4. Operation at low temperatures
If the unit is to be used under low ambient
temperature conditions, its operation may become
unstable immediately after the power is turned on due
to the formation of condensation, etc. To operate the
unit at a low temperature, first set the POWER switch
to the ON position, leave the unit standing for about
an hour, and then insert the disc.
1-5. Concerning write cache operations
This unit performs write cache operations during
recording.
For this reason, if the power is turned off
immediately
upon
completion
of
a
recording
(immediately after the REC lamp has gone off), the
data in the drive buffer may be lost, the data may not
be recorded properly or some other type of trouble
may occur.
Immediately after recording, the drive's BUSY lamp
may
light up orange
for a short while
(several
seconds):
under no circumstances
should be the
power be turned off while this lamp is still lighted.
e Write cache operations
The recording data is transferred to the buffer
(memory) in the unit's drive, and the recording
operation is completed as soon as the data transter
to the buffer is completed.
Starting from this point in time, it is possible to
perform
the next
operation
such
as
INPUT
or
FREEZE.
After this, the unit's drive automatically records the
data from the buffer onto the disc.
To all appearances, it seems that recording can be
performed
at high speed
by the write cache
operation.
1-6. Moving or transporting the unit
When the unit is to be moved or transported, be
absolutely sure to remove the disc and take care not
to drop it or knock it against something.
CAUTION:
Panasonic will not be liabie in any way for the loss of
data or for any damage, whether direct or indirect,
which results from the use of this product or which is
due to its malfunctioning or any other reason.
Make backups (copies) of important data using the
disc copy function in order to safeguard against loss
of data.
