If the hearing aid whistles continuously, it could be
because:
• Your ear is blocked by earwax. Contact your ENT
doctor/physician.
• The tubing is broken. Replace the tubing.
• The tubing is yellow and stiff. Replace the tubing.
• The tubing often comes off the earmould or hearing
aid hook. Replace the tubing.
• The hook or elbow is cracked. Contact your hearing
care professional.
• The earmould is not correctly placed in your ear canal.
Take the earmould out and reinsert it. It is impor-
tant that the earmould is placed correctly in your
ear canal.
• The earmould fit is too loose. Contact your hearing
care professional.
If the hearing aid performs intermittently, it could
be because:
• The on/off switch is dirty. Push the switch back and
forth a couple of times.
