[. . . ] Have your hearing checked by an audiologist on a regular basis. If you experience wax buildup, discontinue use until a medical professional has examined your ears. Failure to use, clean, or maintain earphone sleeves and nozzles according to manufacturer's instructions may increase the risk of sleeves detaching from the nozzle and becoming lodged in your ear. h WARNING FOR ALL EARPHONES! For safe and correct use of earphones, read this manual before use. Keep the manual and safety information in a convenient place for future reference. Safety Precautions The possible results of incorrect use are marked by one of two symbols - WARNING and CAUTION - depending upon the imminence of the danger and the severity of the damage. WARNING Ignoring these warnings may cause severe injury or death as a result of incorrect operation. [. . . ] · Grasp the connector and the earphone as close as possible to where they join. · Pull straight apart--do not twist. · Do not pull on the cable or put any pressure on the earphone nozzle. · Listen for a click when connecting. · When reattaching the cable, match the "L" and "R" markings. For clear cables and earphones, match the color dots (Red = Right, Blue = Left). Note: If you pull at an angle, the connector will not detach. Changing Sleeves Twist and pull to remove the sleeve from the nozzle. Slide on a new sleeve so that it completely covers the barb and the nozzle. Caution: If the barb or any of the nozzle is exposed, the sleeve is not properly installed. Replace sleeves if they do not tightly grip the nozzle. To ensure proper fit and performance, use only sleeves supplied by Shure (unless using custom molded sleeves). Audible click when properly seated Wearing the Earphones The following are some suggested ways of wearing the earphones. Removing the Earphones Grasp the body of earphone and gently twist to remove. Note: Do not pull on cable to remove earphone. Over the ear in back Wearing the cable over the ear and securing it behind the head can help keep the earphones in place during physical activity Tighten the cable and take up slack by raising the cable cinch. Choosing a Sleeve Select an earphone sleeve that provides the best fit and sound isolation. It should be easy to insert, fit comfortably, and easy to remove. Soft Flex Sleeves: In small, medium, and large sizes. Made from pliable rubber. Inserting the Earphones Insert the earphones so they form a tight seal. The fit of the earphone can greatly affect sound quality. Soft Foam Sleeves: Compress the foam sleeve between your fingers and insert into the ear canal. Hold in place for about ten seconds while the foam expands. Triple-Flange Sleeves: If desired, use scissors to trim the stem on the sleeve. Important: If there seems to be a lack of low frequency response (bass), this means that the earphone sleeve is not forming a tight seal. Gently push the earphone deeper into the ear canal or try a different sleeve. Warning:Do not push the earphone sleeve beyond the ear canal opening. 2 Cleaning the Earphone Nozzle If you notice a change in sound quality, remove the sleeve and check the nozzle of your earphone. If nozzle is blocked, clear obstruction by using wire loop end of cleaning tool.
