This document outlines the features, usage, and maintenance of a Mini Smart Home Theater projector. It serves as a quick user guide, providing essential information for safe and effective operation.
Safety Precautions
Before operating the projector, it is crucial to read and understand all safety instructions to prevent damage to the device or injury to the user. The manual emphasizes keeping the product in a safe place for future reference. Users are advised to handle the projector with care, avoiding drops or impacts from high altitudes to protect the internal components. A lens protection cap should always be used after operation to prevent scratches on the lens. Only the standard power adapter provided with the projector should be used to avoid damage to the power cord due to excessive bending or incorrect voltage.
High Temperature Attention
Proper ventilation is critical for the projector's longevity and performance. When the projector is in operation, it is strictly forbidden to block the air inlet or outlet. A minimum distance of 30cm must be maintained between the machine's air inlets/outlets and any walls or obstructions. Failure to ensure adequate ventilation can lead to excessively high temperatures, potentially damaging the device.
Electric Shock Prevention
To prevent electric shock and internal damage, users must ensure that foreign objects such as paper dust, wires, or screws do not fall into the machine. If any foreign object does enter the projector, the power must be immediately turned off, and the object should be removed by professional maintenance personnel. Users are explicitly warned against disassembling the machine themselves, as there are no customer-serviceable parts inside. To further prevent fire and electric shock, the projector should not be exposed to rain or moisture.
