discharged, the ERROR (ALARM) indicator blinks. If this happens,
replace the battery with a new one within a week. The date when the
battery must first be replaced is written on the side panel of the C20. For
example, if it says:
FIRST REPLACEMENT 89/12
This means you should replace the battery by Dec. 1989
