To reduce the risk of fire, electric shock, injury to persons and damage to property, read 
all operating instructions and the following safety instructions before using your Poly 
product. Operating, storage and charging temperature is 10˚C to 40˚C (50˚F to 104˚F).
• Only use those Poly products and accessories designed for use with this product.
• If you experience a skin irritation after using this product, discontinue use and contact 
Poly.
• CHILDREN. Never allow children to play with the product-small parts may be a 
choking hazard.
• Do not disassemble the product as this may expose you to dangerous voltages or 
other risks. Incorrect reassembly can cause electric shock or fire when the product is 
subsequently used.
• Unplug, discontinue use and contact Poly if the product overheats or has a damaged 
outer casing, cord or plug.
• Exposure to high volume sound levels or excessive sound pressure may cause 
temporary or permanent damage to your hearing. Although there is no single volume 
setting that is appropriate for everyone, you should always use your headset/
headphones with the volume set at moderate levels and avoid prolonged exposure to 
high volume sound levels. The louder the volume, the less time is required before your 
hearing could be affected. You may experience different sound levels when using 
your headset/headphones with different devices. The device you use and its settings 
affect the level of sound you hear. If you experience hearing discomfort, you should 
stop listening to the device through your headset/headphones and have your hearing 
checked by your doctor. To protect your hearing, some hearing experts suggest that 
you:
1 Set the volume control in a low position before putting your headset/headphones on 
your ears and use as low a volume as possible.
2 Avoid turning up the volume to block out noisy surroundings. Whenever possible, use 
your headset/headphones in a quiet environment with low background noise.
3 Limit the amount of time you use headsets/headphones at high volume levels.
4 Turn the volume down if the sound from the headset/headphones prevent you from 
hearing people speaking near you.
See poly.com/healthandsafety for more information on headsets/headphones and 
hearing.
• If you use your headset/headphones while driving, check local laws regarding use of a 
mobile phone and headset, and ensure your attention and focus remain on driving 
safely. Use of a headset/headphones that covers both ears will impair your ability to 
hear other sounds and in most regions is illegal to use while operating a motor vehicle 
or riding a bicycle and may be a serious hazard for you and others.
• If this product includes earbuds/eartips, install and use them in accordance with the 
instructions provided. Do not force earbuds/eartips down the ear canal. Consult a 
doctor if they become lodged in the ear canal.
• Plug the mains adapter or charger into a socket-outlet that is near to the equipment 
and will be easily accessible.
