Thank you Awanone for the tip about the MAC address. It is a clever way indeed.
By the way, I am not sure whether I have a defective remote or else. The green light doesn't show up instantly when I press the on/off switch on the remote. In fact it is booting up but the green light turns on only after one of two minutes. I would have thought that it turns on as soon as I press the switch. It also takes longer than I thought to boot up.
