I have just unboxed and setup my new Venu 2 & updated software.
My Pulse ox is set on "All Day".
I've had the watch on my wrist for about 2hrs, yet it has not taken any 0x readings.
When I try to take one - it states: "Unable to take a measurement ....."
I've tried this three times: with the strap on quite firm & my arm/wrist dead-still on a table.
No luck - please advise possible solution?
