BEFORE USE
Notes on handling internal hard disk drive components
This unit uses an internal hard disk drive (HDD).
Be sure to observe the following points carefully when operating,
Conditions to avoid
The hard disk is sensitive to dust, vibrations and shocks, and should also not be used near magnetic objects. To prevent loss of recorded data, observe the following precautions:
zDo not subject the digital video recorder to shocks.
zDo not use the digital video recorder on a vibrating or unstable surface.
zDo not disconnect the power plug from the wall outlet during recording or playback.
zDo not use the digital video recorder in areas of extreme temperature changes (10ºC or more per hour).
zCondensation may occur if the digital video recorder is moved to an area of extremely different temperature or high humidity. If the unit is operated when condensation has formed, it may cause operating problems. If sudden changes in the ambient temperature occur, wait for the temperature to stablize before operating the unit.
zDo not install the digital video recorder in areas of constant vibration such as motor vehicles or trains.
zThe digital video recorder has ventilation holes. Make sure these holes are not blocked after installation.
zDo not use the digital video recorder in areas with poor ventilation, such as a bookshelf or box.
zThe digital video recorder is designed to be placed horizontally. Do not place it in an upright position.
zWhen installing the digital video recorder in a rack, ensure a gap of at least 5 cm at the top and bottom.
zWhen placing the unit down on a surface such as a floor, attach the feet to the base of the unit and place it down gently. If the feet are not attached, place the unit down very carefully.
Do not move the unit for 30 seconds after disconnecting the power.
After the power is disconnected, the disk inside the HDD will continue to spin for a brief period due to inertia, and the heads will be in an unstable state. During this time, the unit is even more susceptible to shocks and vibration than when power is being supplied. Make sure that the unit is not subjected to even gentle vibration for at least 30 seconds after disconnecting the power.
Notes on transporting
When transporting the unit, pack it securely using the packing materials. In addition, use a method of transportation that minimizes vibration.
Notes when replacing the HDD
Be sure to follow the correct replacement procedure when replacing the HDD.
zHDDs that have been removed from their packing may not operate correctly if they are subjected to any shocks and vibration. It is recommended that you place HDD onto a soft, level surface with the printed circuit board facing upward after unpacking it.
zBe careful not to subject the HDD to shocks or vibration when removing and tightening screws as part of the HDD replacement procedure. Make sure that all screws are tightened securely so that they will not become loose. The HDD is sensitive to static electricity, so you should take proper precautions to prevent static electricity buildup.
Handling the HDD unit by itself
If transporting or storing the HDD unit by itself, always be sure to pack it in the packing first. In addition, use a method of transportation that minimizes the vibration.
If the HDD becomes damaged, handle the unit and the damaged HDD that has been removed in order for it to be replaced carefully to prevent the problem from being aggravated until as the nature of the problem can be checked and analyzed.
The hard disk and cooling fan are consumable items.
Under use in an ambient temperature of 25ºC, the hard disk should generally be replaced after 2 years, and the cooling fan after 3 years. These figures are intended as guidelines only, and are not guarantees of part performance.
The POWER indicator flashes if a problem occurs in the hard disk or fan. ( P.11)
For important recordings
zAlways make a test recording beforehand to check that the digital video recorder’s playback is normal.
zNote that no compensation will be provided for losses due to recording or playback problems arising from problems with the digital video recorder or its connected devices during operation.
zTo be prepared for malfunctions or accidents, back up important recordings periodically, or record using mirroring.
Hard disk protection
The hard disk is checked automatically at power ON. If a hard disk problem is found, the POWER indicator flashes. To initialize the disk or save images stored on the disk, contact a Sanyo service center.
