Safety precautions

• Listening at high volumes that irritate your ears can have a negative influence on your hearing.
• Do not use headphones while driving a bicycle, motorcycle or automobile. Doing so could lead to accidents.
• When using headphones, for safety keep the volume to a level at which surrounding sounds can be heard.
  • Do not put in water or dampen.
• Do not place heavy objects on, heat, or pull on the headphones. Doing so could damage or deform them.
  • To prevent injury, be careful not to let your fingers get caught between the housing and hanger.
  • Do not expose to high temperatures.

Do not expose to direct sunlight. Pay particular care with the inside of cars in hot weather. The components may be warped or damaged by high temperatures.

Caution on handling

• Be sure to hold the plug when unplugging the cable.

• Do not place undue stress on the cord, as this can result in wire disconnection or damage. Observe the following for correct usage.

• Do not remove the connecting plug by pulling on the cord.

• Do not pull the cord unduly.
• When connected to a portable device, do not leave the portable device hanging.
• Do not wrap the cord around the portable device.

• If you leave a connected portable device hanging, it may become disconnected and fall. Take care as DENON does not guarantee portable devices.

• The ear pads may deteriorate after extended usage or storage.
  • Always keep the headphones (particularly the ear pads) clean. If they are dirty, this may reduce their performance. Use a soft cloth to gently wipe off the dirt.
• Do not use benzene, thinners, or other organic solvents or insecticides on the main unit since they may cause a change in quality or color.
  • The headphones have a structure by which the sound tends to leak out if the volume is too high. Be considerate of others.
