[AC Question]

Im trying to set the alarm. What does the red dot mean? On or Off. Thank you.

Hi - we will need a lot more info if we are going to help you tbh, what phone do you have? what alarm app are you using? have you tried testing it out, i.e. set an alarm for 5 minutes time and see if it goes off with the "red" dot on and off.

Well certainly, some more info is required. Anyway, in case you are asking about the red button at the side of the time specified, then, it is the sliding switch to indicate on/off. If by sliding, the switch changes to greyish colour, then grey means OFF and red means ON.
