HDD INSTALLATION

Note for Hard Disk Drive
The internal hard disk drive (HDD) is a fragile piece of equipment.
Please follow the guidelines below when using the system to
protect against possible HDD failure. We recommend that you back
up your important recordings onto an external backup device in
order to prevent accidental loss.
Make sure that the power is turned OFF when attaching or
removing the HDD.			3
•	Do not move the system while the power is on.
•	Do not use the system in excessively hot or humid places, or in		Installation
	places that may be subject to sudden changes in temperature.
	Sudden changes in temperature can cause condensation to
	form inside the system. This can be a cause of HDD failure.
•	While the system is switched on, do not unplug from the wall
	socket or switch the electricity off from the breaker switch.
•	If there’s a power failure while the system is on, some data on
	the HDD may be lost.
•	Do not drop the HDD. Also do not put the metallic object such
	as coins or screwdrivers into the HDD tray.
•	When a power failure occurs during recording, avoid adding,
	replacing or transporting the HDD as the recorded data may be
	erased. In this case, turn the power back on to boot up the unit
	normally with the HDD that was being used at the time of the
	power failure attached. Then add, replace, or transport the HDD.
•	The HDD is very delicate. Handle the HDD with care and follow
	the precautions below because even a tiny shock may damage
	the internal components of the HDD.
	-- Do not place the HDD on the desk or table directly. Put a
		thick cushion under the HDD because even a small shock
		may damage the internal components of the HDD.
	-- Do not use an electric screwdriver. Vibrations and shocks
		caused by an electric screwdriver may damage the internal
		components of the HDD.
	-- When replacing the HDD, do not knock the HDD with other
		components such as another HDD and the HDD tray.
	-- Do not knock the HDD with tools such as a driver when
		replacing the HDD.
	-- Protect the hard disk drives from static electricity.
