How To Adjust The Tone Of Your Delkim 

Don't need a button once you have set your tone, spot on. No need for more holes and moving parts in the alarm, Delkim gets it right.

Difficult for my ocd has i like all my alarms exactly the same tone & once you've changed 1 its a right chore to get them all the same, 64 is a bit overkill & not really necessary, better with anout a dozen & a slower sequence when scrolling through. Just my preference & everyones a critic😅
