RS-232 Error Codes
If an errcode ? command returns one of the following values, you have encountered a
likely system error requiring the attention of a qualified service technician. Try resetting the
projector by powering it off, allowing it to cool and powering it on again.
The specific code number identifies the source of the error detected, and is particularly
useful in cases where the projector is far away. For example, the code “7” means that Fan
1 has failed.
