Julian Date
NOTE: Contact the telephone company, if required.
The Julian date for this unit is found on the bottom of the unit.
TAS units are manufactured in:
·Mexico (M)
·Taiwan (H)
·China (G)
·Thailand (L)
The Julian date (XX XXX X) is read as follows:
·The first two numbers (XX XXX X) represent the year (00 - 99) of manufacture.
·The next three numbers (XX XXX X) represent the day of the year (1 - 365) of
manufacture.
·The last letter (XX XXX X) represent the place (M, H, G, L) of manufacture.
So, for example, 92291G was built in 1992, on the 291st day, in China.
When asked if a Julian date is after 92291G, 922209H, or 92168M, compare the Julian
date the customer gives you with the Julian date above for the same manufacturing site.
For example, if the customer said,"93005G," you would compare it to 92291G and
answer, "Yes."
