• Ideal operating temperatures are 0 °C to 45 °C. Ideal
storage temperatures are - 20 °C to 50 °C. Extreme
heat or cold may damage your device or accessories.
• Do not expose your device to direct sunlight (such as on
a car dashboard) for prolonged periods.
• Do not place your device or batteries on or in heating
devices, such as microwave ovens, stoves, water
heaters, or radiators. Batteries may explode if
overheated.

darker pigmentation, may occur.
• If your device has a camera flash, do not use it directly in
the eyes of people or pets. Otherwise temporary loss of
vision or damage to the eyes may occur.

battery. Doing so may result in damage or explosion.
Protecting your hearing when using a headset
•
To prevent possible hearing damage, do not listen at
high volume levels for long periods.
• Using a headset at high volumes may damage your
hearing. To reduce this risk, lower the headset volume
to a safe and comfortable level.
• Exposure to high volumes while driving may cause
distraction and increase your risk of an accident.
