In Case of Difficulty
All Zenith Data Systems (ZDS) computer hardware and software products
are designed to work together as a complete system. Proper operation
can be assured only when your computer is used with ZDS designed
or approved accessories. ZDS does not assume the responsibility for im­
proper operation resulting from custom interfacing, custom software, or
the use of accessories not approved by Zenith Data Systems.
All the computer components have been wired and tested by ZDS.
If
you encounter any malfunction during the warranty period, call your Ze­
nith Data Systems dealer or authorized repair facility to arrange for service.
Do not attempt to service this computer during the warranty period; to
do so may void the warranty.
You may have out-of-warranty products repaired by your Zenith Data
Systems dealer or authorized repair facility. You may wish to obtain a
maintenance contract for your computer system, or you can purchase
individual replacement parts to do your own service.
For the location of the nearest Zenith Data Systems dealer or repair facility,
refer to the Zenith Service Center listing which you received with your
computer.
