EYE PROTECTION– Open by default, the user can close

• Function: When a person approaches, a prompt box will pop up (countdown 5S). If the human is far away within 5 seconds, the prompt box will disappear,r and the light machine will not be turned on. The light machine will be turned off, and it will be turned on automatically when the human body is far away.
• The path for turning off the eye protection function: Settings->system->console settings->Eye Protection
• Fault determination: If the Eye protection board fails, the eye protection function is not effective. If the Eye protection board has a poor connection, the unit does not hit, the indicator flashes 7 times

• Does the subtitle disappear during the dust removal process? → not disappear, keeps prompting
• What happens when the dust removal ends → the subtitle prompt disappears directly after the dust removal ends

Temperature reminder

• Screen prompt: When powered on again, it will prompt “The previous shutdown was due to the high temperature of the laser TV, and it was automatically turned off for protection.”
• Fault determination: If there is a warning of overheating, first check if there are any obstructions around the machine, which may cause poor heat dissipation. If so, remove obstructions.
