Due to their efficiency, intuitiveness, and outstanding visual effects, projectors are known as the "stars" of office equipment. However, to ensure that projectors can operate stably and maintain good performance over time, it is crucial to use and maintain them correctly. Use of Projectors: 1.

When shutting down, the power switch should be turned off first, then the power source disconnected. 2. Adjusting the projection environment: The size and clarity of the projection should be adjusted according to different situations and environments. Ensure that the projection area is not too bright, to avoid interfering with the projected image.

3. Signal source selection: Projectors typically support multiple signal sources such as computers and TV signals. Select the correct signal source and switch as needed.
