Notes on handling removable HDDs

This unit uses removable hard disk drives (HDD).

Be sure to observe the following points carefully when operating, setting-up and servicing the unit.

„Do not subject the unit to shocks or vibration.

If the unit is subjected to shocks or vibration, it may damage the HDD or cause corruption of the data stored in the HDD.

z Do not move the unit while the power is turned on. Always be sure to turn off the power before removing the unit from or placing it onto the rack.

z When transporting the unit, pack it securely using the specified packing materials. In addition, use a method of transportation that minimizes vibration.

z When placing the unit down on a surface such as a floor, attach the specified feet to the base of the unit and place it down gently.

„Do not move the unit 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 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 turning off the power.

„Do not operate the unit when condensation has formed.

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.

„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 specified 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.

Conditions to avoid

zThe 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 digital video recorder is used with condensation inside it, operating problems may occur.

zDo not install the digital video recorder in areas of constant vibration such as motor vehicles or trains.

The hard disk and cooling fan are expendable 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 CHANGE DISK indicator flashes if a problem occurs in the hard disk or fan. (JP. 18)

Installation conditions

The digital video recorder has ventilation holes on its left, rear and bottom panels. Make sure these holes are not blocked after installation.

Do not use the unit in an area of poor ventilation such as a bookshelf or box.

When installing the unit in a rack, ensure a gap of at least 5 cm at the top and bottom.

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.
