5.2.5 Cell Warranty Conditions
The Class A-2C, B-2C or Z-2C Micro-Fuel cell is used in the Model
3190. These cells are warranted for 6 months, with an expected life of 8
months from the date of shipment (under specified operating conditions—see
Appendix). Note any Addenda attached to the front of this manual for
special information applying to your instrument.
Note that the warranty period begins on the date of shipment. The
customer should stock only one spare cell per instrument at a time. Do not
attempt to stockpile spare cells.
If a cell was working satisfactorily, but ceases to function before the
warranty period expires, the customer will receive credit toward the purchase
of a new cell.
If you have a warranty claim, you must return the cell in question to the
factory for evaluation. If it is determined that failure is due to faulty work-
manship or material, the cell will be replaced at no cost to you.
Note: Evidence of damage due to tampering or mishandling will
render the cell warranty null and void.
