Mackie CFXMKII - DIAGRAMS Appendix

Repair
Service for the CFX MKII Series mixers is
available at a factory-authorized service center.
Service for Mackie mixers living outside the
United States can be obtained through local
dealers or distributors.
If your mixer needs service, follow these in-
structions:
1. Review the preceding troubleshooting
suggestions. Please.
2. Call Tech Support at 1-800-898-3211, 8am
to 5pm PST, to explain the problem in
detail. If it appears that the mixer needs
repair, you will be given a Service Request
Number. Have your mixer's serial number
ready. You must have an Service Request
Number before you can obtain service at a
factory-authorized service center.
3. Keep this owner's manual and the detach-
able linecord. We don't need them to repair
the mixer.
4. Pack the mixer in its original package,
including endcaps and box. This is VERY
IMPORTANT. When you call for the Service
Request Number, please let Tech Support
