Easy way to check data communication status through Cell LED

Note
In situations where Cell power is turned on/off or device status (battery, memory, etc.) needs to be notified, the Cell's power operation or status notification LED is prioritized regardless of data communication status.
•
The top LED blinks green. → GPS reception is smooth.
•
The upper LED blinks in rainbow color. → Not getting GPS reception. When you move to an area with a good signal, you can automatically pick up the GPS signal again.
•
The top LED blinks quickly. → HR data reception is smooth.
•
The center LED is off. → If you haven't connected to a Live Hub, it's normal.
•
The center LED starts blinking. → This indicates that communication with the Live Hub has started.
•
The center LED blinks green. → Communication with the Live Hub is smooth.
•
The center LED blinks orange. → Communication with the Live Hub is not smooth. When the distance between the Cell and the Live Hub gets closer, it can automatically pick up the signal again.
