What should be paid attention to when using and maintaining hard disk video recorders?
Please keep the hard disk recorder away from high-temperature heat sources and places.
Please keep the area around the hard disk video recorder well ventilated to facilitate heat dissipation.
Dust on the circuit board can easily cause a short circuit after getting damp, affecting the normal operation of the hard disk video recorder and even damaging the hard disk video recorder. In order to ensure that the hard disk video recorder can work stably for a long time, please regularly remove dust from the circuit board connector, chassis, fan chassis, etc.
Please ensure that the project has good grounding measures to avoid interference with video and audio signals, and to prevent the hard disk video recorder from being damaged by static electricity or induced voltage.
Please do not plug or unplug audio and video signal cables and other interfaces while the power is on, otherwise these ports will be easily damaged.
Try not to use a TV on the local video output interface of the hard disk video recorder, otherwise the video output circuit of the hard disk video recorder will be easily damaged.
When shutting down the hard disk video recorder, please do not turn off the power switch directly. Try to use the shutdown function in the menu, or press the shutdown button on the panel for more than three seconds to make the hard disk video recorder automatically turn off the power to avoid damaging the hard disk.
Please perform regular system inspection and maintenance.
