Safety warnings

Safety Instructions

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 HP product. Operating, storage and charging temperature is 10°C to 40°C (50°F to 104°F).

• Only use those HP products and accessories designed for use with this product.
• If you experience a skin irritation after using this product, discontinue use and contact HP.
• 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 HP 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.

• 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.

Battery Warnings for Wireless Products

• If your product has an embedded, non-replaceable battery, do not attempt to open the product or remove the battery as this may cause injury and/or damage the product. If your product has a replaceable battery, use only the battery type supplied by HP. Remove a spent battery promptly.
• Replace rechargeable batteries after three years or 300 charge cycles, whichever occurs first.
• Do not dispose of the product or battery in a fire or heat above 40°C (104°F).
• Do not expose the battery to extremely high temperatures. It may result in an explosion or the leakage of flammable liquid or gas.
• Do not open, deform or mutilate the battery. There may be corrosive materials which can cause damage to eyes or skin and may be toxic if swallowed.
• Never put batteries in mouth. If swallowed, contact a physician or poison control center. Swallowing may lead to burns, perforation of soft tissue, and death. Severe burns can occur within 2 hours of ingestion.
• Always store batteries where children cannot reach them.
• Do not allow any battery or its holder to contact metal objects such as keys or coins.
• RECYCLING: The product battery must be recycled or disposed of properly. Contact your local recycling center for battery removal and proper disposal.
• Use only the charger supplied by HP to charge the product and follow the charging instructions provided. Alternatively, if your headset is designed to be charged with your cell phone charger, use only cell phone chargers approved and provided by your cell phone manufacturer.
