turning the alarm off on HTC-1 clock humidity temperature meter

As seen in this video, in order to set the alarm, short-press Mode, then long press Mode till minutes start blinking. In order to turn alarm on or off, press mode again, set the hours, press mode again, and now when in Alarm setting mode without the numbers blinking, press the Adj button to toggle through Alarm on, (tone every 15 minutes I think) and Alarm off. If the unit is just left alone for a minute, the current time display returns. Or we can short-press Mode again to come out of Alarm set mode. 

So, in short, if we just want to toggle Alarm on or off, just short press Mode and then short press Adj repeatedly to toggle through the Alarm on or off modes.
