provider for more information.

minimum distance of 15 cm be maintained between 
a device and a pacemaker to prevent potential 
interference with the pacemaker. If using a 
pacemaker, hold the device on the side opposite the 
pacemaker and do not carry the device in your front 
pocket.

 To prevent possible hearing damage, do 

not listen at high volume levels for long periods.

hearing. To reduce this risk, lower the headset
