BLUETOOTH communications may be disabled, or noise or audio dropout may occur under the following conditions.
- There is a human body between the headset and the BLUETOOTH device. This situation may be improved by placing the BLUETOOTH device facing the antenna of the headset.
- There is an obstacle, such as metal or wall, between the headset and the BLUETOOTH device.
- A device using 2.4 GHz frequency, such as a Wi-Fi device, cordless telephone, or microwave oven, is in use near this headset.
- The situation may be improved by changing the wireless playback quality settings or fixing the wireless playback mode to SBC on the transmitting device. For details, refer to the operating instructions supplied with the transmitting device.
- Because BLUETOOTH devices and Wi-Fi (IEEE802.11b/g/n) use the same frequency (2.4 GHz), microwave interference may occur resulting in noise or audio dropout or communications being disabled if this headset is used near a Wi-Fi device. In such a case, perform the following.
- Use this headset at least 10 m (30 feet) away from the Wi-Fi device.
- If this headset is used within 10 m (30 feet) of a Wi-Fi device, turn off the Wi-Fi device.
- Install this headset and the BLUETOOTH device as near to each other as possible.
- In case that you enjoy music with your smartphone, the situation may be improved by shutting down unnecessary apps or restarting your smartphone.
