Introduction
Contact HTC or your nearest retailer if you have any questions or quiries. 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 ma-
chine sign placed on the inside of the door to the electric cabinet.
It is possible to read the manufacture date of the machine from the serial number. For in-
stance 80511080, where 8 represents the model - this is an HTC 800 HDX. The next six numbers
are the date of manufacture. The last number is a sequence number and 0 shows that this is the
first machine built that day.
Good luck.
