The listener wears the receiver which picks up the signal from the microphone and delivers it to the ear through an earpiece on the child's hearing aid. The hearing aid is a delicate instrument. Ideally, the aid should be checked for repairs needed and cleaned by an audiologist at least once a year. Careful handling and proper maintenance will help prolong the life of the child's hearing aid to a typical useage of about 5 - 7 years. Hearing Aid Care Avoid High Temperatures - Don't leave the hearing aid in the direct sunlight, in a hot car, on a heater, or on any other piece of equipment that generates heat.
Heat can damage the hearing aid amplifier and can cause batteries to deteriorate.
Moisture - Keep the hearing aid dry. Even perspiration can cause damage to the hearing aid. Protect the Aid from Hard Knocks - Avoid dropping the hearing aid or bumping it against hard objects. Repairs - Do not attempt to repair the hearing aid. If the aid is not functioning properly, ask the audiologist or hearing aid dealer for assistance.
