•   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.
•   Stop using your device or applications for a while if the 
device is overheated. If skin is exposed to an 
overheated device for an extended period, low 
temperature burn symptoms, such as red spots and 
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.
