CMS50F oximeter locked up - and FIX!
While changing some settings in my pulse oximeter it locked up and became totally unresponsive -- freak software glitch I guess. I could have left it on until the battery went dead but that could take quite a while. This model has a non-removable, (well, not intended to be removed) USB rechargeable battery. A small phillips screwdriver allowed me to take the unit apart. I momentarily short circuited where the battery leads are soldered to the circuit board and the unit turned off. Now working normally. I hope this helps somebody.
