Safety Information
Please read all of the safety information carefully before using your device to
ensure its safe and proper operation and to learn how to dispose of your device
properly.
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.
• Keep the battery away from fire, and do not disassemble, modify, throw, or
squeeze it. Do not insert foreign objects into it, submerge it in water or other
liquids, or expose it to external force or pressure, as this may cause the battery
to leak, overheat, catch fire, or even explode.
• Dispose of this device, the battery, and accessories according to local
regulations. They should not be disposed of in normal household waste.
Improper battery use may lead to fire, explosion, or other hazards.
