Hi @Anonymous User
Not aware of a method of remote controlling the nowtv box from a different location.
Would your Dad be able to press & hold the microphone button on the smart remote and say "Sky Sports" .
This should open Sky Sports News (first Sky Sports channel on the list) then use the down arrow on remote which will scroll down the channels where the channel name will display on the television screen then press the OK button on the remote to select the Sky Sports channel he wants to watch.
The only other button that might be worth learning (if possible) is the home button if for some reason the box doesn't automatically fire up when selecting the television HDMI input source button.
Also i would suggest going into your Father's NowTV account under My Account > Settings & Pins and add a payment pin just in case your father accidentally purchases other NowTV passes via his box.
A payment pin will then ask for a four digit security code if he accidentally presses the wrong buttons should he mistakenly get into the buy passes section on the box.
