About this task
To reduce the risk of fire, electric shock, personal injury, and property damage, read all operating instructions and the following
safety instructions before using this device.
● Use only products and accessories designated for this device.
● If skin irritation develops after using this device, stop using the device and contact DELL.
● Do not let children play with small parts of the device, as they may enter the child's airways and cause choking.
● Do not disassemble the device as this may result in electric shock and other risks. Improper disassembly may cause electric
shock if the phone is used again.
● If the device overheats or is damaged to the case, cord, or plug, unplug it and discontinue use.
● Using the device at high volume levels or at elevated sound pressure levels may cause temporary or permanent damage to
your hearing. There is no specific volume setting that works for everyone, however, you should always adjust the volume of
your headset or headphones to a medium level and avoid prolonged exposure to high volumes. The louder the sound, the
faster it will lead to hearing impairment. When you use a headset or headphones with different devices, the volume of the
playback sound may differ. The volume of the emitted sound depends on the device used and its settings. If you experience
any discomfort, you should stop using this device with a headset or headphones and have your hearing checked by a doctor.
To protect your hearing, experts recommend the following
1. Decrease the audio volume before turning on the headset / headphones, and use the volume as low as possible.
2. Do not try to increase the volume in order to drown out the surrounding noise. If possible, use the headset / headphones
in a calm environment with low background noise.
3. Limit the time you use your headset / headphones at high volume levels.
4. Decrease the volume if the sound from the headphones or headset interferes with the speech of people around you. For
more information on headsets or headphones and hearing related aspects, see plantronics.com/healthandsafety.
● If you use a headset or headphones while driving, check your local laws for mobile phones or headsets and focus on ensuring
safe driving. Using a headset or earbuds covering both ears when driving, including bicycle, reduces your ability to hear other
sounds and can pose a significant risk to you and others, and is illegal in most countries.
● If in-ear / in-ear headphones were supplied with this unit, connect and use them according to the instructions provided. Do
not use force to insert the in-ear / in-ear headphones into the ear canal. If they get stuck in the ear canal, consult your
doctor.
● Use only chargers supplied by DELL to charge your device and follow the charging instructions provided. In addition, if the
headset is to be charged using a cell phone charger, use only chargers approved and supplied by the cell phone manufacturer
for that model. Do not use the charger for any other purpose. Make sure the operating voltage matches the voltage of the
power supply.
