parts, and must not be opened. 

A Bluetooth device use radio signals to communicate with other devices. The power 

of this radio signal is low, maximum 0.001 Watts. Do not use the product where it is 

forbidden, for example in air planes, at hospitals, in blasting areas or in explosive 

atmospheres. Radio signals may interfere with other electronic devices, especially if 

these are not shielded.

 

 

Permanent hearing loss may occur if headsets are used at high 

listening volumes for longer periods of time.

 Set the volume to a safe 

level. You can adapt to high listening volume over time, especially in a noisy 

environment where the level of sound may seem normal even if the volume is high. 

Reduce the time you use a headset with high listening volume. 

 

Battery information 

The device is equipped with a rechargeable Lithium-polymer battery. A new battery 

will need a few charging cycles before it can reach maximum capacity. A fully charged 

battery will loose its charge over time even if the headset is not used. 

 

Battery capacity and life span may be reduced if the device is exposed to extreme 

high or low temperatures, for example if it is left in a car. A device with a cold or hot 

battery may stop working until it is back to normal (room) temperature. Battery 

capacity at temperatures below -0   

o

C is reduced. 

 

Never dispose of batteries in open fire since they may explode. Always dispose of 

use batteries and electronic devices according to local recycling regulations.
