Use & Safety for Battery-Powered Accessories
• Do not store or use your battery-powered accessory (such as a Bluetooth®
headset or other device) in temperatures below -10°C (14°F) or above 60°C
(140°F).
• Do not recharge your accessory in temperatures below 0°C (32°F) or above
45°C (113°F).
• Conditions inside a parked car can exceed this range. Do not store your
accessory in a parked car.
• Do not store your accessory in direct sunlight.
• Storing your fully charged accessory in high-temperature conditions may
permanently reduce the life of the internal battery.
• Battery life may temporarily shorten in low-temperature conditions.
Caution About High Volume Usage
Warning: Exposure to loud noise from any source for extended periods of time may
temporarily or permanently affect your hearing. The louder the volume sound level,
the less time is required before your hearing could be affected. Hearing damage
from loud noise is sometimes undetectable at first and can have a cumulative effect.
To protect your hearing:
• Start your volume control at a low setting and use as low a volume as
possible.
• Limit the amount of time you use headsets or headphones at high volume.
• Where possible, use your headset in a quiet environment with low
background noise.
• Avoid turning up the volume to block out noisy surroundings.
• Turn the volume down if you can’t hear people speaking near you.
If you experience hearing discomfort, including the sensation of pressure or fullness
in your ears, ringing in your ears, or muffled speech, you should stop listening to the
device through your headset or headphones and have your hearing checked by your
doctor.
