The power indicator (a white light) to the corresponding projector’s status is as follows:
– Connect to the power outlet, the projector automatically turns on.
– The indicator blinks when the projector is turning on.
– The indicator turns off after the project is turned on.
– The indicator blinks when the projector is turning off.
– The indicator turns off after the projector is turned off.

Note:
– Pay attention to the positive and negative poles when installing batteries in the remote control.
– When the battery leaks, immediately wipe away any fluid with a dry cloth and replace the batteries with new ones.
– Dispose of used batteries according to local waste disposal rules and regulations of the country or area you live in.

Projection Distance & Screen Size

Determine the distance between the projector and the wall or screen according to the desired screen size.

Screen Dimensions (SD)| Projection Distance (D)| Relative Height (H)
---|---|---
80″| 14 cm| 29 cm
90″| 19 cm| 32 cm
100″| 24 cm| 35 cm
120″| 34 cm| 41 cm
150″| 49 cm| 50 cm

Screen Dimensions (SD): The diagonal size of the projection screen (in inches).
Projection Distance (D): The distance between the projector and the wall or screen (in cm).
Relative Height (H): The distance from the bottom of the projector to the bottom edge of the projected image (in cm).

Note: The dimensions in the table above are for reference only, they are approximate and may slightly differ from the actual values.

Suspended Ceiling Installation
Suspended ceiling installation is one of the installation methods that you hang the projector in an overhead location, for example, on a high ceiling, through a ceiling mount. A projector supporting suspended ceiling installation has threaded holes on the bottom, you can install the project on the mount by attaching the screws into the holes. The  installation steps are as follows:

1. Install the mount.
   Make sure the mount used to install the projector can support at least five times the weight of the projector. It requires a professional to carry out the installation.

2. When installing the projector onto a ceiling mount, make sure the screws meet the following specifications: Screw Type: Non-self-tapping screw M4 × 10 (diameter: 4 mm,
   length: 10 mm), 4 pcs. Assembly Dimensions: See the figure on the right.

3. Adjust the amount depending on your needs and firmly fix the screws to complete the installation.

Cautions:
– To avoid the convective heat transfer between the air inlets and air outlets, make sure there are no obstructions within 50 cm of the air inlets and heat dissipation vents.
– Keep the bottom of the projector 10 cm away from the ceiling when suspending it.
– Damage caused by the incorrect installation will void the warranty.

Network & Internet
Go to Settings > Network & Internet. Select a wireless network to connect to, enter the password, and wait for the projector to connect.

Smart Temperature Control
The projector automatically monitors the ambient temperature (operating temperature range is 0°C to 40°C), projector temperature, and color wheel temperature, and the projector’s fan speed is automatically adjusted based on the detected temperature values.
– The projector has three brightness modes to choose from when operating at a normal temperature. To adjust the projector’s brightness level, go to Settings

Image > Brightness Mode.
– If the projector gets too hot, and an overheating warning will appear and the projector will automatically switch to low brightness mode. Temperature and error warnings will be displayed automatically whenever the temperature exceeds its maximum range to inform you that the projector will be automatically turned off.

Safety & Protection
The projector comes with an infrared sensor that is able to intelligently detect and protect the human eye from damage caused by strong light within the projected area. The projector will reduce its brightness to the lowest possible value when the sensor is triggered and issue the following notification: “Do not look directly at the light source.” Press any button on the remote to exit.

Human infrared sensor &
fresnel optical lens| Front sensor range: Approximately 55°| Left and right side sensor range:
Approximately 70°
