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. Refer to Table 6-3
and contact your dealer if the problem persists.
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.
