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, setting-up, or servicing the digital video

recorder.

 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.

z Do 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.

z When transporting the digital video recorder, pack it

securely using the specified materials. In addition,

choose a method of transportation that minimizes

vibration.

z When 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.

z HDDs 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.

z Take 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.

z The 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:

z Do not subject the digital video recorder to sudden

impact.

z Do not use the digital video recorder on a vibrating or

unstable surface.

z Do not disconnect the power plug from the wall outlet

during recording or playback.

Do not use the digital video recorder in areas with extreme

temperature changes (i.e., 10ºC or more per hour).

z Condensation 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.

z Do not install the digital video recorder inside motor

vehicles, trains, or other areas under constant vibration.

z The digital video recorder has ventilation holes on its

left, rear, and bottom panels. Ensure that these holes

are not blocked after installation.

z Do not use the digital video recorder in a bookshelf,

box, or any other area with poor ventilation.

z This digital video recorder is designed for use in a

horizontal orientation, and vertical setup may result in

malfunction.

z When installing the digital video recorder in a rack,

ensure that a gap of at least 5 cm is provided at the top

and bottom.
