SAFE USE
Use a slow twisting motion to remove the earphones. Never pull on
the earphone cord.
Warning: If a sleeve becomes lodged in your ear, seek skilled medical
assistance to remove the sleeve. Damage to the ear may be caused
by non-professionals attempting to remove the sleeve.
Prior to inserting the earphone, always recheck the sleeve to make
sure it is firmly attached to the nozzle.
 Turn up the volume control only far enough to hear properly.
Ringing in the ears may indicate that the volume level is too high. Try
lowering the volume.
If you connect these earphones to an airplane’s sound system, listen
at low levels so that loud messages from the pilot do not cause
discomfort.
Have your ears checked by an audiologist on a regular basis. If you
experience wax buildup, discontinue use until an audiologist has
examined your ears.
Stop using the earphones if they are causing great discomfort or
infection.
