9. System Update
- At least once a year, update the drivers and the BIOS. This article explains how to proceed with those updates.
10. System clean up
We recommend cleaning Lü's equipment from accumulated dust at least once a year using a can of compressed air. Be careful not to push dust into the camera lenses.
11. Long-Term Inactivity Procedure for Lü System
- When your Lü system will not be in use for several days or weeks (e.g., during summer vacation), it is recommended that you turn off the circuit breaker on which Lü is installed. This procedure will protect your Lü from any electrical power surges in the event of a power failure.
Before turning off the breaker:
- Turn off the computer.
- Turn off the projector.
When you return, allow time for system updates before using your Lü system.
