Safety information
This section contains important information about how to use your device safely and how 
it operates. Read this information carefully before using your device.
Electronic device
Do not use your device if its use is prohibited or if it may cause danger or interference 
with other electronic devices.
Interference with medical equipment
• Adhere to any rules or regulations set forth by hospitals and health care facilities.
• Some wireless devices may affect the performance of hearing aids or pacemakers. For 
more information, contact your service provider.
• Pacemaker manufacturers recommend maintaining a minimum distance of 15 cm 
between a pacemaker and a wireless device to prevent potential interference with the 
pacemaker. If using a pacemaker, hold the device on the side opposite the pacemaker 
and do not carry the device in your front pocket.
Protecting your hearing when using a headset
•  To prevent possible hearing damage, do not listen at high volume levels for 
long periods. 
• Using a headset at high volumes may damage your hearing. To reduce this risk, lower 
the headset volume to a safe and comfortable level.
• Exposure to high volumes while driving may cause distraction and increase your risk of 
an accident.
Areas with flammables and explosives
• Do not use the device in environments where flammables or explosives are stored, such 
as a petrol station, because the electronics in the device may trigger an explosion or 
fire. Always adhere to any warning signs or information that may be present in these
