Precautions
• The use of hearing instruments is only part of hearing
rehabilitation; auditory training and lip reading
instruction may be required as well.
• In most cases, infrequent use of hearing instruments
does not provide full benefit. Once you have become
accustomed to your hearing instruments, wear your
hearing instruments everyday all day.
• Your hearing devices use the most modern
components to provide the best possible sound
quality in every listening situation. However,
communication devices such as digital cell phones
can create interference (a buzzing sound) in hearing
devices. If you experience interference from a cell
phone being used close by, you can minimize this
interference in a number of ways. Switch your
hearing devices to another program, turn your head
in a different direction or locate the cell phone and
move away from it.
Labeling
For most ITE hearing instruments, the year of
manufacture is located above the serial number. The
first two digits indicate the year of manufacture.
