Identification information
Your hearing instruments have a serial number
engraved on them. The location of the serial
number will vary according to the style of
hearing instrument you have chosen.
The year of manufacture is incorporated into
the serial number. Please note the warranty is
based upon the date of purchase, not the date
of manufacture.
The serial number may look similar to this
sample: AV12345. The second letter of this
serial number refers to the year of manufacture
of the hearing instrument. The letters U or V
indicate a 2009 year of manufacture. Your
Audiologist or Hearing Care Professional can
answer any questions you may have about
the identifying code on your hearing
instrument.
Record the serial numbers of each instrument
in the space provided for future reference.
