About This Watch
This section provides an overview of the watch and introduces convenient ways it can be used.
Watch Features
The watch supports connection and communication with a Bluetooth capable phone.
You can use Life Log to measure your distance, calories burned, and step count. After you specify a daily target, a graphic display shows approximately how much of the target you have achieved and how much more you need to do.
Dual Time lets you keep track of a second time, such as the current time in another time zone, etc.
An alarm sounds whenever a time specified by you is reached.
Use the Stopwatch Mode to measure elapsed time.
Up to 45 lap/split time records can be recorded in watch memory.
The timer counts down from a specified start time. A beep sounds for each of the final five seconds. You can configure multiple time intervals for consecutive countdowns, which comes in handy for set training.

The illustrations included in this operation guide have been created to facilitate explanation. An illustration may differ somewhat from the item it represents.
