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).
