Problem Possible cause Solution
The watch calculates decompression
diving even after a dive.
The diver ascended defying the
decompression stop violation warning.
When the surface interval time is less than 5 minutes, making a
decompression stop as indicated by the watch will return the
display for no-decompression diving.
**The log data stored in the dive log function will not be erased when the battery is replaced with a new one. If any malfunction is found during
checking, however, the stored log data may be erased when the watch is repaired. It is recommended that the log data in memory be noted down
in your log book before requesting a battery change.
