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.
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 first few times it is used. Do not expose the
battery to extreme temperatures, never above +50°C or below -10°C.
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
and +45°C.
