The system does not turn on and the indicator on the
front panel does not work at all.
y Check if the power supply system is properly connected.
y Check the system for the input voltage from the power source.
y If the problem persists even after you have taken the above actions,
check the power supplier and replace it with a new one if neccessary.
Some channels display just a black screen even if
they receive video sources.
y Check if the camera connected to the system properly displays the
image. Sometimes, this problem may occur on a camera that is not
properly connected to the video source.
y Check if the camera is properly supplied with power.
y Sometimes, this problem may occur on a channel with weak video
signal from a video distributor that is connected to multiple systems. In
this case, input the video source of the camera directly into the DVR.
This may find the cause and solve the problem.
If I press the [REC] button, the REC indicator does
not flash, nor the player start recording.
y Check if there is a free space on the HDD for the recording.
y Check if the record mode is set to ON in the record mode setting.
The screen displays the logo image repeatedly. y This may occur from a problem with the main board, or the related
software is corrupt.
Contact the nearest service center for more information.

monitoring mode.

start the calendar search.

with the Start button.
When the alarm sounds, I press the [ALARM] button
to release the alarm but it does not work. The alarm
persists and I could not set it off in any way.
y Press the [MENU] button to release the alarm in the following way:
1) To release the event monitoring mode : Monitoring Mode – set the
duration of the event monitoring to Off.
2) To release the alarm sound : Event Record Mode - Alarm (Motion
Detection/Video Loss/Tampering Detection) – deactivate the alarm
sound.

in the PTZ device are properly configured according to the PTZ camera.
I've found that the DVR does not recognize as many
disks as installed when I have connected multiple
external HDDs to the DVR.
y It takes time for the DVR to recognize multiple external HDDs. Try again
in a moment and if the problem (of failure to recognize as many HDDs
as connected) persists, it may occur due to a mechanical error of the
HDD installed. Try again with a different HDD.
