Roughhandling can break internal circuit boards.PaintDo not paint the mobile device. Paint can clog thedevice’s moving parts or ventilation openings and preventproper operation.Responsible ListeningCaution! Avoid potential hearing loss.Damage to hearing occurs when a person is exposed to loudsounds over time. The risk of hearing loss increases assound is played louder and for longer durations.Prolonged exposure to loud sounds (including music) is themost common cause of preventable hearing loss. Somescientific research suggests that using portable audiodevices, such as portable music players and cell phones, athigh volume settings for long durations may lead topermanent noise-induced hearing loss. This includes the useof headphones (including headsets, earbuds, and Bluetooth®or other wireless devices).Exposure to very loud sound has also been associated insome studies with tinnitus (a ringing in the ear),hypersensitivity to sound, and distorted hearing. Individualsusceptibility to noise-induced hearing loss and potentialhearing problem varies. Additionally, the amount of soundproduced by a portable audio device varies depending on thenature of the sound, the device settings, and the headphonesthat are used. As a result, there is no single volume settingthat is appropriate for everyone or for every combination ofsound, settings, and equipment.You should follow some common sense recommendationswhen using any portable audio device:• Always turn the volume down before plugging the earphones intoan audio source.• Set the volume in a quiet environment and select the lowestvolume at which you can hear adequately.• Be aware that you can adapt to higher volume settings over time,not realizing that the higher volume may be harmful to yourhearing.
