Charging with the Charger Cable

Charging with the charger cable is faster than solar charging.

Important!

Use only the supplied charger cable for charging.

A device with a USB port (Type-A) can also be used for charging.

Note that no guarantees are made concerning the suitability of all types of USB ports for charging. If charging is not possible for some reason, disconnection from the USB port is recommended.

Place the charger on a desk or other stable surface, making sure there is plenty of open space around it. Charging with the charger and watch in a bag or some other enclosed space can cause overheating of the watch.

Should water or any other liquid get onto the watch or charger cable during charging, immediately unplug the charger cable from the power source.

Perform charging in an environment where ambient temperature is between 5 °C and 35 °C (41 °F and 95 °F).

Avoid pinching your hands or fingers in the gap of the clip of the charging cable.

Charging from a Non-computer Device’s USB Port

You can charge using power from a USB port (Type-A) that meets USB standards.

Voltage: 5 V

Current: 0.5 A min.

Precautions When Charging

A charging operation will not start while the battery level indicator shows 3515_icon_inl_HIGH. To prolong the life of the watch’s rechargeable battery, charge only while the battery level indicator shows 3515_icon_inl_batt_Lv_2 or lower.

Do not attempt charging at high ambient temperatures of 35 °C (95 °F) or greater. The watch becomes hot during charging, which can cause charging to stop automatically. High ambient temperature may result in a less than full charge.

Operation on a custom computer or a computer that has been modified from its original configuration is not guaranteed.

The watch may become warm during charging. This is normal and does not indicate malfunction.

Note

Starting from a blank display, it takes about 3.2 hours to achieve a full charge.

Charging time depends on ambient temperature and other factors.
