Troubleshooting
World Time
Q1The time for a World Time City is not correct.
The summer time setting (standard time/summer time) is wrong.
Diving Function
Q1I can’t enter the Dive Mode.
The watch does not enter the Dive Mode while its charge is low or dead. Charge the watch before using it for diving.
Q2The watch enters the Timekeeping Mode when it switches from dive time measurement to surface interval measurement.
If the charge becomes low while in the Dive Mode, the watch is not able to perform surface interval measurement. Charge the watch before using it for diving.
Q3Measurement is in progress when I switch from the Timekeeping Mode to the Dive Mode.
This happens when a previous measurement is being continued. Enter the Dive Mode and reset measurement.
Tide Level
Q1There are errors in the tide information.
Since the high tide and low tide times and tide levels of the Tide Graph are calculated based on past data, the calculated data may be different from actual tide information.
Also note that the degree of the error can be affected by terrain, weather, and other conditions. Use the tide information of this watch for reference only.
Be sure to check accurate tide forecast information issued by various organizations, and do not use the tide information of this watch to determine tide levels used for navigation or any other purpose where there is the risk of danger.
Alarm and Hourly Time Signal

Charging
Q1The watch does not work even though it is exposed to light.
The watch stops operating whenever the battery goes dead. Keep the watch exposed to light until it recharges sufficiently.
Q2[H], [M], and [L] are flashing on the display.
The watch is in the charge recovery mode. Wait until the recovery process is complete (about 15 minutes). The watch will recover more quickly if you place it in a brightly lit location.
If an alarm, hourly time signal, illumination and/or other power-intensive functions are used within a short period of time, the charging capacity of the battery will drop and cause the watch to go into a charge recovery mode. Function availability will be temporarily limited, but functionality will return after the battery recovers.
Q3[CHG] is flashing on the display.
The charge level of the watch is extremely low. Immediately expose the watch to light to charge it.
