Within the period of this warranty, Retro Instruments will replace or repair at no charge

Instruments neither assumes nor authorizes any representatives or other persons to
assume for the company any other liability in connection with the sale or any shipment of
Retro Instruments products. There are no other warranties, expressed or implied, given
by Retro Instruments extending beyond or different from the express warranty stated
herein.
Retro Instruments reserves the right to make changes and improvements in its products
without incurring any obligation to similarly alter products previously purchased.
This warranty shall be void in the event this product is materially altered after shipment
of the product from Retro Instruments, except this warranty shall not be void if such
alteration is authorized in writing by Retro Instruments for the individual customer.
