Proper Care
• Do not expose earphones to extreme temperatures.
• Avoid dropping or strong impact. Extreme shock can damage the earphones.
• Always leave an ear tip on the earphone for shock protection.
• Perspiration entering the nozzle may cause the earphone to temporarily stop
working. Normal operation usually resumes after the earphone dries out.
• Do not pull on the cord to remove it from the jack or the ear.
• Clean or replace the ear tips prior to use and following by others.
• Replace disposable foam ear tips regularly.
• Earwax buildup can reduce the earphone output. When the lters become clogged, they should be replaced. See Changing Filters.
Caution
Consult a physician or audiologist if you have excessive cerumen, difculty inserting the ear tips, or discomfort after prolonged use. It
is unsafe to use insert earphones while driving a motorized vehicle, operating machinery, bicycling or jogging, because you may not be
alerted to potential danger. Do not use the earphones at excessively loud levels. Noise-induced hearing loss is a result of exposure time, the
average sound level and the peak of very loud sounds. Decreased listening levels allow for longer periods of safe listening time.
