Warranty
The manufacturer provides two years warranty on all products, free of change, but the users should be responsible for the one-way transportation fee from the customer to the factory.

Service
The manufacturer provides instrument installation for our customers, and the charges will be made according the cost. For any hardware failure of the instrument, we recommend that our customers send back the instrument to our factory for service, due to the fact that the instrument is made of microprocessors and it will be difficult to perform field maintenance. Before sending back the instrument, please try to contact the factory first to make sure what the problem is.
For other operational problems, please contact our service department by telephone, fax or email and internet. In most cases, the problems could be solved immediately.

Software Upgrade Service
We provide free-of-charge software upgrade services. Please contact the factory for any lately developed software.
