3. Potentially explosive atmosphere
Power 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 re 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, 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 powered 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.
5. Battery information
A rechargeable battery has a long service life if treated properly. A new
battery or one that has not been used for a long period of time could
have reduced capacity the rst few times it is used. Do not expose
the battery to extreme temperatures, never above +50°C (+122°F) or
below -10°C (+14°F). For maximum battery capacity, use the battery
at room temperature. If the battery is used in low temperatures, the
battery capacity will be reduced. The battery can only be charged in
temperatures between 0°C (+32°F) and +45°C (+113°F).
