Troubleshooting when a Flashing Warning Mark ( ) Appears
A fl ashing warning mark ( ) in the Diving Mode means some problem occurred during a measurement, or
that there was some operation error. The warning mark also will appear (without fl ashing) whenever the
log data that was recording during the measurement problem or operation error is displayed. Log data for
which the warning mark appears should not be used for dive planning or other purposes because it
contains large error. Also, data that is stored in the Diving Mode while the warning mark is fl ashing is
assigned a CAUTION number (which also appears in the log data record), which identifi es the type of
problem that occurred.
For details about each type of problem, refer to the pages in the table below.
