Introduction
Contact HTC or your nearest reseller if you have questions or comments. Make sure to have the
serial number of your machine available when you call, since all machines are registered and this
helps us provide you with the best possible service. The serial number is located on the right-
hand side of the chassis (seen from behind) and on the right-hand fixing lug. It is also found on
the machine sign located on the electrical housing
It is possible to read the manufacture date of the machine from the serial number. In the example
of 89704240, 8 represents the model - this is an HTC 800. The next six numbers are the date of
manufacture. The last number is a sequence number and 0 indicates that this is the first machine
built on this day.
Best wishes!
