CAUTION
• It may not be possible to send or receive commands for about 10 to 60 seconds when the lamp is first turned on. If this occurs, wait for 60 sec-
onds, then try sending or receiving again.
• When sending multiple commands, be sure to wait for at least 0.5 second after receiving a response from the projector before sending the next
command.
• Additional time is sometimes required for response due to processing inside the projector. Set the time-out period for command response to 10
seconds or more.
