3. Keep this owner's manual and the detachable line-
cord. We don't need them to repair the preamp.
4. Pack the preamplifi er in its original package,
including endcaps and box. This is VERY IM-
PORTANT. When you call for the Service Request
Number, please let Tech Support know if you need
new packaging. Mackie is not responsible for any
damage that occurs due to non-factory packaging.
5. Include a legible note stating your name, shipping
address (no P.O. boxes), daytime phone number,
Service Request Number, and a detailed description
of the problem, including how we can duplicate it.
6. Write the Service Request Number in BIG PRINT on
top of the box. Units sent to us without the Service
Request Number will be refused.
7. Tech Support will tell you where to ship the pream-
plifi er for repair. We suggest insurance for all forms
of cartage.
8. We'll try to fi x the preamplifi er within three to fi ve
business days. Ask Tech Support for the latest
turn-around times when you call for your Service
Request Number. The preamp must be packaged in
its original packing box, and must have the Service
Request Number on the box. Once it's repaired, we'll
ship it back the same way in which it was received.
