Safety precautions
•Never disassemble or modify your headset for any reason. Doing this may cause the headset to malfunction or become combustible. Bring the headset to an authorised service centre to repair it or replace the battery.
•When using your headset while driving, follow local regulations of the country or region you are in.
•Avoid storage at high temperatures (above 50 °C/122 °F), such as in a hot vehicle or in direct sunlight, as this can damage performance and reduce battery life.
•Do not expose the headset or any of its supplied parts to rain or other liquids.
Excessive exposure to sound at high volumes can cause hearing damage. Always turn the volume down before plugging the earphones into an audio source and use only the minimum volume setting necessary to hear your conversation or music.
