Make sure there is good air circulation
around the DVR.
This DVR uses an internal hard drive,
which generates heat during operation
for video storage. Do not block vents
on the DVR, as these vents disperse
the generated heat while the system
is running. Place this product in well-
ventilated area.
Do not attempt to remove the top
cover. If you observe any abnormal
operation, unplug the DVR
immediately and contact technical
support. Do not attempt to open the
DVR to diagnose the cause of the
problem.
Handle the DVR carefully.
If you drop the DVR, it may damage
the device. If the DVR doesn't work
properly due to physical damage,
contact an authorized dealer for repair.
It is recommended to use your DVR
with an uninterruptible power supply
(UPS). Connecting your DVR and
cameras to a UPS allows continuous
operation even during power outages.
The run-time duration will depend on
the rating of the UPS used.
