Safety Precautions
• To avoid any damage, please consider the following safety warnings:
• Never place the recorder near to heaters, furnaces, other heat sources or under direct solar irradiation.
• Operate the device only in locations providing the tolerable operating temperature range
0°C~40°C/32°F ~ +104°F.
• Make sure that the device's ventilation slots are not covered or sheeted.
• For cleaning, make sure the device is plugged off and only use a damp cloth without acid detergent.
• Install the device only in dry and dustproof surroundings. Protect the device against any liquid's
penetration.
• Avoid the penetration of any artifacts, e.g. through ventilation slots.
• Do not attempt to disassemble the appliance. To prevent electric shock, do not remove screws or
covers. There are no user-serviceable parts inside. Contact qualified service personnel for maintenance.
Handle the appliance with care. Do not strike or shake, as this may damage the appliance.
• Do not operate appliance with other than specified power supplies. The input power source of the power
supply is 100 ~ 240 VAC.
• Avoid any affection of the device through vibrations or mechanical shock at the recorder's installation
location.
• Avoid to power off DVR during playback or recording operation.
"Rack Mount Instructions - The following or similar rack-mount instructions are included with the installation
instructions:
A) Elevated Operating Ambient - If installed in a closed or multi-unit rack assembly, the operating ambient
temperature of the rack environment may be greater than room ambient. Therefore, consideration should
be given to installing the equipment in an environment compatible with the maximum ambient temperature
(Tma) specified by the manufacturer.
B) Reduced Air Flow - Installation of the equipment in a rack should be such that the amount of air flow
required for safe operation of the equipment is not compromised.
C) Mechanical Loading - Mounting of the equipment in the rack should be such that a hazardous condition
is not achieved due to uneven mechanical loading.
D) Circuit Overloading - Consideration should be given to the connection of the equipment to the supply
circuit and the effect that overloading of the circuits might have on overcurrent protection and supply wiring.
Appropriate consideration of equipment nameplate ratings should be used when addressing this concern.
E) Reliable Earthing - Reliable earthing of rack-mounted equipment should be maintained. Particular
attention should be given to supply connections other than direct connections to the branch circuit (e.g. use
of power strips)."
