60174. Please include a note describing the malfunction and suspected
cause of failure. The Company shall not be obligated to repair or replace
units which are found to be defective because of damage, unreasonable
use, modifications, or alterations occurring after the date of manufacture.
In no case shall the Company be liable for any consequential or incidental
damages for breach of this or any other Warranty, expressed or implied
whatsoever, even if the loss or damage is caused by the Company's negli-
gence or fault. Some states do not allow the exclusion or limitation of inci-
dental or consequential damages, so the above limitation or exclusion may
not apply to you. This Warranty gives you specific legal rights, and you
may also have other rights which vary from state to state.
