Notes:
1.The charging time required varies with the intensity of light. (Refer to the table in
“CHARGING/RECHARGING INFORMATION”)
2.When the watch is fully charged, it will keep operating for approximately 3 days.
3.It is recommended that you keep the watch charged by exposing it to an appropriate light source from time to time, rather than letting it run down fully before recharging.
4.The watch is equipped with a system to prevent overcharge. Even if it is further exposed to light after being fully charged, no malfunction will result.
5.It is recommended that the watch be fully recharged before time setting is attempted.
