Maintenance
1. If the equipment is not in long-term use, disconnect the power switch when not in
use and disconnect the AC power adapter from the AC socket.
2. When removing dust from the outer shell of the equipment, please use soft cloth or
cotton paper to avoid scratches.
3. When cleaning equipment lens, please use dry soft cloth to wipe. If the equipment is
heavily soiled, please use neutral detergent to wipe gently. Do not use strong or
corrosive detergents to avoid lens scratches and affect image effects.
Troubleshooting
1. Video output without image:
- Check whether the power supply of the equipment is properly connected and
whether the power indicator is on.
- Whether the power-off restart equipment is normal or not.
- Check whether the bottom dial switch is working in normal mode.
- Check whether the connection of video output and video display is normal.
2. Images are sometimes absent: Check whether the connection of video output and
video display is normal.
3. Lens zoom image jitter:
- Check whether the installation position of the equipment is firm or not.
- Check whether there are vibrating machines or objects around the equipment.
4. Remote control is uncontrollable:
- Check whether the remote control address is set to 1 controllable (if the
equipment restores to the factory default value, the remote control address is also
restored to 1).
- Check whether the remote control battery is installed properly or the power
supply is insufficient.
- Check whether the working mode of the equipment is normal.
- Check whether the menu has not exited; it can be controlled normally after exiting
the menu. If the page outputs images, it will not display the menu and do nothing.
After 30 seconds, the menu automatically exits and can be controlled.
5. Serial port can't be controlled:
- Make sure the serial port is well connected by the company cable.
- Make sure the protocol, baud rate and address of serial devices are consistent with
the equipment.
- Check whether the control line is connected properly.
6. Web pages cannot be logged in:
- Check whether the equipment is working properly with the display.
- Check whether the network connection is normal (the yellow indicator flashes at
the outlet, indicating that the network connection is normal).
- Check whether the computer adds a network segment and the network segment is
identical to the device IP address.
