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.
•
Ideal operating temperatures are 0 °C to 35 °C. Ideal storage
temperatures are -40 °C to 70 °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.
•
Observe local laws and regulations while using the device. 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 illegal.
•
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.
