There’s a button, underneath on the black box, on the side on the Stick, and with the device powered, you press this and hold it in for 15-30 seconds. (Less time, and it only power cycles off/on).
The device then needs to be set up again, with account details and all, so if you want your husband to be able to do this in your absence, walk him through it, make copious notes, and then have him demonstrate that he can do it without assistance, so you can safely leave him with it.
Any chance someone can give me more explicit instructions?
I have plugged and unplugged broadband box and NOWTV box,
I have reset both broadband box and NOWTV box,
and the only difference is an extra second or two before the screen freezes.
