Turn off your electronic device when in any area 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.
