Please is the TV on/off switch to send video HDMI output to a TV on the 250a or only on Rose Connect. May somebody guide as to what menu screen will get me to it? There is NO MENTION of the switch in the manual. This should be corrected.
If you look at the part marked in red below, you will see the title of the video being played.
Please click on it and watch the video above again.
Then you will be moved to the video playback screen on your Rose device and you will see the TV ON/OFF icon at the top right of the screen as shown in the picture below.
