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. 

Do not drop, knock, or shake the mobile device. Rough 
handling can break internal circuit boards. 

Do not paint the mobile device. Paint can clog the 
device’s moving parts or ventilation openings and prevent 
proper operation. 

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 

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
