The problem is in the battery holder of the CR1220
battery.
-Take out the CR1220 battery (the little round one).
-When
you replace it, put a bit of aluminum foil against the back, between the
battery and the plastic holder, to make it a nice tight fit. One layer won't do
it, but don't put in half the roll.
-Put it
back in. Done
Using a
fresh battery & clean it all with alcohol = good idea as well. Worked for me.
