Operation and safety
•  
 To prevent possible hearing damage, do not 
listen at high volume levels for long periods.

Using an unapproved or incompatible power adapter, 
charger, or battery may damage your device, shorten its 
lifespan, or cause a fire, explosion, or other hazards.

storage temperatures are -20 °C to 45 °C.
•  
Pacemaker manufacturers recommend that a 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.

Keep the device and the battery away from excessive heat 
and direct sunlight. Do not place them on or in heating 
devices, such as microwave ovens, stoves, or radiators.

To reduce the risk of accidents, do not use your wireless 
device while driving.

While flying in an aircraft or immediately before boarding, 
only use your device according to instructions provided. 
Use of a wireless device in an aircraft may disrupt wireless 
networks, present a hazard to aircraft operation, or be

To prevent damage to your device's parts or internal 
circuits, do not use it in dusty, smoky, damp, or dirty 
environments or near magnetic fields.
