Module No. 3515

After using an activity function, use the charging cable to charge the watch.

Activity measurement is not possible while the battery indicator shows or lower. Charging before performing an activity measurement is recommended.

If [MEMORY FULL] appears on the display while an activity measurement operation is in progress, the measurement operation stops.
Measurement also stops automatically whenever a single activity measurement operation exceeds 80 hours.

You may not be able to save measurement results if the remaining activity log capacity is low. If this happens, delete log data you no longer need to make room for more data.

For information about the summary (Measurement Result) screen that appears after an activity measurement operation is complete, see the information below.

Activities that use GPS cannot be selected while Airplane Mode is turned on.
