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.
