Important Safeguards

Please read the manual carefully before operating the projector.

Installation

To achieve better viewing, use this projector in a dark room or with curtains drawn.
Handle the projector with care. Dropping or impact may damage parts, leading to blurred images or abnormal display.

Power

Be cautious when using the power cord. Avoid excessive bending, as damage to the cable can cause electric shock and fire.
It is recommended to unplug the power cord after turning off the projector.

Cleaning

Unplug the power cable before cleaning.
Clean the projector shell regularly with a damp cloth and neutral detergent.
Use a glasses cloth or lens paper to clean the lens, avoiding scratches.
Regularly clean the projector's vents and speakers with a brush to prevent blockages.

High Temperature Attention

The exhaust port area will be very hot during and immediately after projection. Avoid touching it to prevent burns.
Do not look directly into the projector lens during operation, as it may cause eye injury.
