ON, it may stop responding to RS-232 commands. If the projector does stop responding to RS-232
control, manually power down the Epson projector. Once the projector cools down, unplug the projector
from the outlet and allow it 15 seconds to reset. Reapply power and the projector should work normally.
Note: When the projector is placed in STANDBY MODE: NETWORK ON the projector fan remains on in
standby mode. This is normal projector behavior.
