The projector can not receive any command for approximately 10 seconds after the lamp is switched on
and for approximately 1 second after the cooling fan stops operating and the projector has returned to
standby mode (approximately 90 seconds after the indicator switches off).
Be sure to wait until the lengths of time mentioned above have passed before sending the command.

If sending multiple commands, check that a response has been received from the projector for one
command before sending the next command.

When a command which does not require parameters to be sent, the colon (:) is not required.

If an incorrect command is sent from the personal computer, the ER401 command will be sent from the
projector to the personal computer.
