should never be fitted on patients with perforated eardrums, exposed middle ear cavities, or surgically altered ear canals. In the case of such a condition, we recommend to use a customized ear mold.
Precautions
•The use of hearing devices is only part of hearing rehabilitation; auditory training and lip reading instruction may be required as well.
•In most cases, infrequent use of hearing devices does not provide full benefit. Once you have become accustomed to your hearing devices, wear your hearing devices 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.
