ovens, etc.) is placed near the devices being used.
- When using a Bluetooth device (TV, laptop, etc.) other than the mobile phone, the sound quality may
be affected by the specications and performance of the device.
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 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
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 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).
