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.

• Extreme temperature or pressure change after
entering the Diving Mode
• Battery is low so measurement is impossible.

• Frequent appearance of Err-1 can indicate watch malfunction. Contact an authorized CASIO service
center.
• Appearance of C-1 through C-7 indicates an operation error. Refer to the applicable pages for
E-10
information.
Important!
• When TYO (Tokyo) is selected as the Home City, the water depth unit
is set automatically to meters (m) and the temperature unit to Celsius
(°C). These settings cannot be changed.

To specify temperature and water depth display units

1. In the Timekeeping Mode, hold down A for at least two seconds.
• First, SET Hold will fl ash on the display, and then CITY will appear
in the upper display. Keep A depressed until CITY is displayed.
After that, the currently selected city code and city name will scroll
across the upper display.
2. Press C as many times as necessary until UNIT appears on the
display.
• See the sequence in step 2 of the procedure under "To change the
current time and date settings manually" (page E-32) for information
about how to scroll through setting screens.
1. In the Timekeeping Mode, press C once.
• This enters the Diving Log Mode. LOG appears on the display for
