Q: Why the video recorder has no image display and the VFD only displays a "Video Quality" frame during startup?
A: Please check the following:
(1) Are the power cable and data cable of the hard disk connected firmly?
(2) Is the master/slave jumper of the hard disk set correctly? Please contact with your vendor immediately, if above items are correct but the video recorder can't start up normally.
Q: After startup, the video recorder keeps on recording, the Alarm indicator lights up, and the Record indicator lights up, but video recording can't be stopped, why?
A: The digital video recorder is not connected to the alarm sensor but was set to open-circuit alarm and has not been reset; as the result, the video recorder deems an alarm exists and thereby keeps on recording. To solve this problem, connect a short-circuit wire to the alarm input to reset alarm; then, the video recorder will stop after the preset recording time.
Q: Why the monitor has no image display?
A: Check as follows:
(1) Check whether the hard disk is mounted correctly, whether the jumper is set in MASTER position;
(2) Power on the video recorder, and check whether there is time display on the VFD; if there is, it indicates the video recorder is in normal state. Next, check other devices (e.g., whether the monitor and the camera are powered on, whether the video is connected correctly, etc.);
Q: Why the video recorder doesn't provide alarm output after it alarms?
A: Enter into "Alarm Recording" menu item from the menu, and check whether the "Arm" is set to "Arm" and whether "Out" is set; if they are normal, observe the display screen to verify the ALA mark at bottom left corner of the VFD screen will lights up and a sound can be heard (indicates the relay device in the machine has closed) when there is alarm input.

A:
(1) Check whether the system date and time is the current time;

Q: How to treat if the buzzer beeps after startup?
A:
(1) The product has a feature that it will alarm automatically in case of video loss. The buzzer beeps to indicate there is no video input.
(2) Observe whether the “Loss” on the left of the VFD screen flashes; if the “Loss” flashes, it indicates there is no video input.
(3) Check whether there is a dialog box that prompts "Disk Full, Overwrite?" for the video content on the monitor; if there is, please choose "OK"; then, enter into the menu, and modify "Overwrite" under the " Recording" menu item to "Y" with "+" and "-" buttons, and then save and exit.
(4) If the buzzer beeps just after startup of the video recorder, please check the video content on the corresponding monitor to see whether there is a prompt "Set to Hard Disk Mode" at top left corner of the video; if there is, enter into "Working Mode Settings" menu item and set the working mode correctly.
(5) If the buzzer beeps just after startup of the video recorder, please check the video content on the corresponding monitor to see whether there is a prompt "Time Error! Please set time." at the top of the monitor; if there is, enter into "Data & Time Settings" menu item and set the date and time correctly.
(6) If the buzzer beeps once the "Record" button is pressed down, please check the monitor corresponding to the video recorder to see whether there is a prompt "Unformatted Hard Disk X" (X may be A, B, C, or D) at the top of the monitor; if you are sure that hard disk X has not been used before, please enter into "Format Hard Disk" menu item and format hard disk X.
