Frequently Asked Questions - S400 OPTOMA
How to replace the lamp of the OPTOMA S400 projector?
Turn off the projector and unplug it. Let it cool for 30 minutes. Open the lamp cover using a screwdriver. Remove the old lamp and insert the new one (ref. SP.8A01.001). Close the cover and reset the lamp counter in the menu.
What is the maximum resolution supported by the S400?
The native resolution is Full HD (1920 x 1080). It accepts signals up to 4K (3840 x 2160) via HDMI, but scales them down to Full HD.
How to clean the projector's air filter?
Turn off the device and unplug it. Remove the filter located on the side. Clean it with a vacuum cleaner or with warm soapy water. Let it dry completely before reinstalling. Replace it every 1000 hours.
The projector does not turn on, what to do?
Check that the power cord is properly connected and that the outlet works. If the power indicator flashes, the lamp has probably reached the end of its life. Consult the manual for error codes.
How to connect a computer to the projector?
Use an HDMI or VGA cable depending on the outputs available on your PC. Connect the cable to the corresponding input on the projector, then select the source in the 'Source' menu.
Can I use the projector wirelessly?
The S400 does not have built-in Wi-Fi connectivity. You can use a wireless HDMI adapter (sold separately) or an external streaming device.
How to adjust focus and image size?
Use the zoom ring on the lens to adjust the size, and the focus ring for sharpness. The keystone correction wheel allows adjusting lateral distortions.
What does the flashing red light mean?
A flashing red light indicates overheating of the projector. Check that the air intakes are not blocked, clean the filter, and ensure adequate ventilation. Turn off the device, let it cool for 20 minutes before turning it back on.
How to reset the lamp counter?
Go to the menu 'Settings' > 'Lamp counter reset' (or equivalent). Confirm with 'OK' to reset after a lamp replacement.
What type of HDMI cable to use for best quality?
Use a High Speed HDMI cable for reliable Full HD transmission. For 4K, opt for a Premium High Speed cable.
