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.

Chapter 8 Safety warnings

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
