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 -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.
•
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.
•
In order to avoid damaging the internal circuit of the
device or charger, do not use the device in a dusty,
damp, or dirty place, or near a magnetic field.
•
When charging the device, make sure the power
adapter is plugged into a socket near the devices
and is easily accessible.
•
Unplug the charger from electrical outlets and the
device when not in use.
•
Do not use, store or transport the device where
flammables or explosives are stored (in a gas station,
oil depot, or chemical plant, for example). Using your
device in these environments increases the risk of
explosion or fire.
