Notes

Commands are represented in hexadecimal notation. ID1 is projector control ID, ID2 is model-specific code, LEN is data length, and CKS is low-order byte of sum of all preceding bytes. Picture, sound, and onscreen mute may be cleared by input or video signal switching; sound mute may also be cleared by volume adjustment. Lamp usage information updates once per minute despite one-second resolution.
