Why BenQ projector does not respond to commands when it is turning on?

[Timshd]

I have pressed the power button of the BenQ projector for half minites, but why there is no response when I press the remote control? It does not respond to any other commands, and I have to wait a long time before I can use it. Is this a bug? Does anyone know why?

The projector will not respond to any commands within 90 seconds after it is turned on because it is still in the process of starting up.

In addition, the projector will not respond to any commands when it is turned off because it is in the process of shutting down.

It's just turning on.... you have to wait
