Matters needing attention in the use of curtains:

1, when plugging and unplugging the VGA cable, be careful not to forcibly operate it, and also pay attention to whether the D-type interface is consistent, so as not to break the pins of the VGA interface.

2. Users are not allowed to repair and open curtains by themselves. The internal cable parts should be replaced with original parts as far as possible, and it is forbidden to plug and pull cables with electricity.

3. When the curtain is not moving, the travel switch should be set at the O position to avoid burning out the motor.

4. When the equipment is idle, such as Saturday, Sunday and holidays. To put away the power plugs of projectors, speakers and curtains, pay attention to waterproof and moistureproof, turn off the plug-in power supply, and completely cut off the power supply.

5, pay attention to dust. In an environment with less dust, the service life of curtains can be prolonged. When cleaning, pay attention to sprinkling water on the ground to minimize dust raising, and close the doors and windows when not in use to prevent sand from blowing in.

6. Avoid frequent lifting of curtains, which is not conducive to protecting the normal service life of curtains.
