Important Safeguards

Installation

To achieve a better projection effect, it is recommended to draw the curtain or use the projector in a dark room. If the projector is on, ensure there is no strong or direct light around the projection screen. Use the projector carefully; dropping or crashing may damage parts or result in blurred images and abnormal displaying.

Power

Be careful while using the power cord. Avoid excessive bending; the damage of the power cable may cause electric shock and fire. It is better to unplug the power cord after power off.

Cleaning

Unplug the power cable firstly. Clean the shell regularly with a damp cloth; neutral detergent can be used. Please use a glasses cloth or lens paper, avoid scratching the lens. Please clean projector's vents and speakers regularly by banister brush, or the ventilation will be blocked.

High Temperature Attention

While projection or just finishing, the exhaust port nearby will be very hot. If you touch it, you could get scald. While projection, do not look at the lens directly, or it may hurt your eyes.

Warm Tips

Do not disassemble the projector; there will be a risk of electric shock, and unauthorized disassembling will void the warranty. Do not put any liquid or heavy stuff on the projector. To ensure the stability of heat dissipation, please open the height bracket in the bottom of the projector before starting.

How to maintain the Air Purifying Filter

To maintain the air cleaning performance of the filter, please clean or replace the filter regularly. Depending on the frequency of use, it is recommended to replace the filter element every 3 to 6 months. The system will also display a reminder to replace the filter element when the accumulative use time reaches 500 hours. Please replace the filter element according to the tip.

Follow the instructions below to pull out the air filter frame on the bottom of the projector. Then use a dry brush to gently sweep away the dust on the surface of the filter element.
