Scandisk when the resume function is enabled
If Scandisk runs when the resume function is enabled, the screen given right may appear.
The BHT displays the screen for three seconds and then automatically runs the execution program from
the beginning.
(The screen may also appear when the calendar clock built in the BHT stops, even without running
Scandisk.)

The resume function is used to return the display to the status (screen) when the power was last
turned OFF when the power is next turned ON.
Resume function settings are made at the "SET SYSTEM" menu. Refer to "Chapter 4 System
Operation" – "4.5.6 System Environment Settings (SET SYSTEM Menu)" for further details.
