Safety Warnings

Safety Instructions

• Only use 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.

• 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.
