My HMI is not saving the time.

My HMI is not saving the time.

You may notice that after cycling power to your LS HMI that the internal clock has reset back to 12:00.  You may also notice that your "HK" keep registers are not saving after a power cycle. This occurs because, by default the battery backup is disabled. 

Remove the battery/DIP switch cover on the back of the HMI.  Below you can see the default settings. 
Note that switch 1, for the Battery, is OFF.


Move the position of switch 1 to the UP (ON) position.
