Aiphone Warranty identification dates
Q. How can I tell when a unit was manufactured to identify warranty?
A. All units have a label attached with the model number and lot number.
The last 3 digits excluding the R of the lot number indicates year and month.
X, Y and Z in the months indicate October, November and December respectively.
(i.e. TG53122 R >>> 2012 February, HH0214X R >>> 2014 October)
