If the noise continues, there may be interference on your phone itself, and any noise in the phone's connection will come through on the headset, too. Transfer the call to your phone and see if the audio quality improves. If it doesn't, look around for things that can interfere with your phone. Safety and Handling Information For maximum product life, do not drop, throw, or crush the headset. Do not expose it to humidity, dust, or temperatures above 125 F. Cleaning the headset • If necessary, remove the earhook. Dampen a lintfree cloth with water or a cleaner specially designed for electronics, and gently wipe the headset clean. • Do not expose this product to liquid (water, alcohol, etc.) or submerse in liquid for any reason. Avoiding hearing damage Using any headset or earbud at too high a volume can cause permanent hearing damage. To reduce the risk of hearing damage: • Set the volume at the minimum level needed to hear in the current environment. If possible, use your headset in quiet surroundings or try to move to an area with less background noise before adjusting the volume. • Start with the volume at its lowest setting, then gradually increase it until you can hear. • Turn the volume down before powering off the headset and readjust the volume each time you turn it on. • If someone next to you can hear the other end of the call through your headset or if your ears hurt or ring when you hang up, the volume is too high. • The longer your ears are exposed to noise, the greater the risk of damage. Limit calls at higher volumes (or other exposure to loud noise). • For more information on protecting your hearing, visit the WISE EARS® website (www.nidcd.nih. gov/health/wise/) or consult an audiologist.
