When using a D2™ Air device connected to headphones using Bluetooth^® technology, the signal is strongest when there is a direct line of sight between the device and the antenna on the headphones.

• If the signal passes through your body, you may experience signal loss or your headphones may become disconnected.

• It is recommended to wear your headphones with the antenna on the same side of your body as your D2 Air device.

• Since headphones vary by model, you can try moving the watch to your other wrist.
