6. Maintenance and Troubleshooting
6.1 Product Maintenance
1) If the device is not for long-term service, please turn off its power switch and disconnect the AC power adapter
from AC outlet when it's left unused.
2) Please use soft fabric or tissue paper to remove dust from housing of the device to avoid scratch.
3) Wipe the device lens with a dry soft cloth when cleaning the lens; please gently wipe it with a neutral cleaner in
the case of serious contamination. Do not use strong or corrosive cleaners, since this may cause lens scratch
and impair image effect.
6.2 Troubleshooting
1) Video output without image
Solutions: a. Check whether the power supply is connected properly, and whether the power indicator is on
b. Check whether the device performs proper self-test after power-off and restart
c. Check whether the connection cables of video output and video display are in good condition
2) The image cuts in and out
Solution: a. Check if the connection cables of video output and video display are in good condition
3) Image dithering during lens zoom
Solution: a. Check whether the device is securely installed
b. Check whether there is any vibrating machinery or object around the device
4) Remote control failure
Solutions: a. Check if control is available when the address of remote control is set to 1 (if the device returns
to the factory default, the address of remote control will return to 1)
b. Check if the battery for remote control is properly installed or low
c. Check whether the menu is still active, since normal control is impossible with active menu; if
the webpage outputs images, the menu will not be displayed.
If no operation is performed, the menu will be automatically deactivated in 30s, and the control will
be available.
5) The serial port cannot be controlled
Solutions: a. Check whether our standard control cable is used.
b. Check the serial device protocol, baud rate and address for consistency with the device
c. Check whether the control cable is properly connected
6) The webpage cannot be logged in
Solutions: a. Use the display to check if the device outputs images properly
