Sensor 2.04 ABOUT and SETUP not Responding to Button Hits
Pressing ABOUT or SETUP on a CEM with software version 2.04 causes the CEM to reboot.
This is not problem that has been seen often. Currently, it is believed that the problem is isolated to version 2.04. If Generating defaults does not solve the problem, the CEM should be upgraded to version 2.14.
Upgrades are done on a very limited basis due to availability of st 90 chips.
