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.
