3. Potentially explosive atmosphere
Turn off your electronic device when in any area with a potentially
explosive atmosphere. Although this is uncommon, your electronic device
could generate sparks. Sparks in such areas could cause an explosion
or fire resulting in bodily injury or even death. Areas with a potentially
explosive atmosphere are often but not always clearly marked.
4. Emergency calls
IMPORTANT!
This Bluetooth headset and the electronic device connected to the
headset operate using radio signals and mobile and landline networks
as well as user-programmed functions, which cannot guarantee
connection under all conditions. Therefore, you should never rely solely
upon any electronic device for essential communications (e.g., medical
emergencies). Remember, in order to make or receive calls, the headset
and the electronic device connected to the headset must be switched on
and in a service area with adequate mobile signal strength. Emergency
calls may not be possible on all mobile phone networks or when certain
network services and/or phone features are in use. Check with your local
service provider.
