Tap one end of the white ridge on doppel's face, then the other end, and then the end you started with again. It does not matter which end you start with, you can tap 'top, bottom, top' or 'bottom, top, bottom'.
doppel will always start on your slow rhythm.
To turn off, repeat the gesture.
I find the ‘off’ gesture is easier than the ‘on’ gesture
Make sure to 'press' carefully instead of 'tapping' quickly.
When doppel is off, it senses for gestures ever so slightly less regularly than when it's on, so the careful press usually makes all the difference.
Sometimes doing the battery gesture first can help and lets you know if doppel is short of battery.
How you wear doppel improves touch response
doppel should be worn with the metal base pressed against the inside of your wrist, on the point where you would expect to feel your pulse.
You can wear your doppel on either wrist.
How you wear doppel also makes a difference to the touch gestures. To get the best response from the touch gestures doppel should be worn so the white ridge aligns directly under your thumb.
