Maintenance and Troubleshooting
This smart projector is a high-tech product integrating precision optics,
•
electronics, and machinery. The improper maintenance of the projector during
the daily use will affect its service life and effects. For the maintenance, important
attention shall be paid to:
Dust prevention: Excessive dust will affect the heat dissipation of the projector
•
due to environmental impact. It is suggested to clean its dust filter once a month
according to the actual environment.
Ventilation: As the projector integrates the sound and photo-electricity, the
•
optical source will product heat during operation. Therefore, during the
installation and use, it shall be ensured that no objects around will block the air
inlet and outlet of the projector as the heat dissipation depends on cold air
convection to improve its working stability and service life.
Lens maintenance: Lens, as the core component of the projector, is directly
•
related to the picture definition and effect. The excessive dust will therefore
affect image quality. The dirty lens shall be wiped with soft cotton cloth. Hard
cloth or abrasives shall not be used.
Cleaning: Excessive dust on the projector surface shall be cleaned in a timely
•
manner, as it will affect the heat dissipation.
Moisture protection: The projector is vulnerable to damp air. Its operating
•
humidity is between 45% to 60%. If the air is too damp, it will affect projector's
working stability.
Vibration prevention: The projector shall be strictly protected from strong
•
impact, extrusion, and vibration. Try not to move and knock the projector during
its normal operation, which may cause internal circuit faults.
The projector shall not be installed on unstable, shaking and uneven desks.
•
Container with liquid shall not be placed on the projector.
•
The power shall be switched off or the power cord shall be unplugged when the
•
device is not in use.
Fault
Power failure
Power-on failure
Network connection
failure
Successful connection
but no internet access
Solution
Check whether the power cord is plugged in and whether
the switch is on.
Check whether the remote control has battery inserted and
the polarity is correct.
Check whether Wi-Fi is turned on. Check whether the
password is correct. Restart the router.
Check whether the network environment is normal and
whether other devices can normally use the Wi-Fi. Restart
the router. Restart the projector.
