Cleaning solutions Do not use harsh chemicals, cleaning solvents, boiling water, or strong detergents to clean the mobile device, as these may corrode and damage silicone and urethane gaskets. To clean, wipe the device with a soft cloth slightly dampened in a mild soap-and-water solution. Shock or vibration Do not drop, knock, or shake the mobile device. Rough handling can break internal circuit boards. Paint Do not paint the mobile device. Paint can clog the device's moving parts or ventilation openings and prevent proper operation. Keypad Surface Swelling: Your mobile device may swell due to drastic atmospheric changes, such as when used at high altitudes or when aboard aircraft. This is normal. If this happens, open the USB Port cover and gently tap keypad to release air that may be trapped inside 157 the device. Close the USB port cover carefully to avoid trapping excess air. If the keypad swells, take care to avoid damaging protrusions. Responsible Listening Caution! Avoid potential hearing loss. Damage to hearing occurs when a person is exposed to loud sounds over time. The risk of hearing loss increases as sound is played louder and for longer durations. Prolonged exposure to loud sounds (including music) is the most common cause of preventable hearing loss. Some scientific research suggests that using portable audio devices, such as portable music players and cell phones, at high volume settings for long durations may lead to permanent noise-induced hearing loss. This includes the use of headphones (including headsets, earbuds, and Bluetooth® or other wireless devices). Exposure to very loud sound has also been associated in some studies with tinnitus (a ringing in the ear), hypersensitivity to sound, and distorted hearing. Individual susceptibility to noise-induced hearing loss and potential hearing problem varies. Additionally, the amount of sound produced by a portable audio device varies depending on the
