3-3-2. Error Messages
An error message is displayed when an error is found during self-diagnostics
and when an arithmetic operation or data setting error is found. A self
diagnostics error message is displayed for about 2 seconds, and the operation
shifts to CHECK (some errors may cause it inoperative). When an arithmetic
operation or data setting error message is displayed, the operation stops.
Table 3-1 lists the error messages; the cause of each message may be found
in any other place than those listed below.
