IDENTIFICATION INFORMATION
Your hearing aids have a serial number imprinted on them. The
location of the serial number will vary according to the style of
hearing aid. Record the serial number in your user guide for
future reference.
The year of manufacture is incorporated
in the serial number. For custom aids, the
year of manufacture is derived from the
first two digits.
For BTE and RIC aids, the year of manufacture is derived from the
second digit:
