Notes on handling the internal HDD
This digital video recorder uses an internal hard disk drive (HDD).
Be sure to observe the following points carefully when operating,
Do not subject the digital video recorder to sudden impact or vibration.
If the digital video recorder is subjected to sudden impact or vibration, it may damage the HDD or cause corruption of the data stored within it.
zDo not move the digital video recorder while the power is turned on. Always ensure that the power is turned off before removing the digital video recorder from or placing it in a rack.
zWhen transporting the digital video recorder, pack it securely using the specified materials. In addition, choose a method of transportation that minimizes vibration.
zWhen placing the digital video recorder on the floor or another similar surface, attach the specified pads to its base and place it down gently.
Do not move the digital video recorder for 30 seconds after turning off the power.
After the power is turned off, the disk inside the HDD will continue to spin for a brief period due to inertia, and the heads will be in an unstable condition.
During this period, the digital video recorder is even more susceptible to damage from sudden impact and vibration than when it is turned on. Make sure that the digital video recorder is not subjected to even gentle vibration for at least 30 seconds after turning off the power.
Do not operate the digital video recorder when condensation has formed on it.
If the digital video recorder is operated in this type of condition, there is a possibility that it will be permanently damaged.
If the temperature around the digital video recorder changes suddenly, wait for it to stabilize before operating the digital video recorder.
Notes on replacing the HDD
Be sure to follow the correct procedure when replacing the HDD.
zHDDs that have been removed from their packing may not operate correctly if they are subjected to sudden impact or vibration. It is recommended that you place the HDD on a soft, level surface with the printed circuit board facing upward after it has been unpacked.
zTake care to avoid subjecting the HDD to sudden impact or vibration when removing and tightening screws as part of the HDD replacement procedure. Tighten all screws securely to ensure that they do not loosen.
zThe HDD is sensitive to static electricity; accordingly, you should take the appropriate precautions to prevent the buildup of static charges.
Handling a detached HDD unit
If transporting or storing the HDD unit in a detached condition, be sure to first of all pack it using the specified materials.
In addition, choose a method of transportation that minimizes vibration.
Notes on installation locations
The hard disk is sensitive to dust, sudden impact, and vibration; furthermore, it should not be used near magnetic objects. The following precautions should be observed in order to prevent the loss of recorded data:
zDo not subject the digital video recorder to sudden impact.
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 with extreme temperature changes (i.e., 10ºC or more per hour).
zCondensation may occur if the digital video recorder is moved to an area with a significantly different temperature or high humidity. If the digital video recorder is used while condensation is present inside it, operating problems may occur.
zDo not install the digital video recorder inside motor vehicles, trains, or other areas under constant vibration.
zThe digital video recorder has ventilation holes on its left, rear, and bottom panels. Ensure that these holes are not blocked after installation.
zDo not use the digital video recorder in a bookshelf, box, or any other area with poor ventilation.
zThis digital video recorder is designed for use in a horizontal orientation, and vertical setup may result in malfunction.
zWhen installing the digital video recorder in a rack, ensure that a gap of at least 5 cm is provided at the top and bottom.
