I'm sorry, but without knowing the specific model of your Matrix Auto Chromatic Tuner, it's difficult for me to provide you with an exact manual. However, I can provide you with some general tips on how to locate a manual for your tuner:

1. Check the manufacturer's website: The first place to look for a manual is the manufacturer's website. Most manufacturers provide manuals for their products on their website, and you can usually search for the manual by entering the model number of your tuner.
2. Search online: You can also try searching for the manual online using search engines like Google or Bing. Enter the model number of your Matrix Auto Chromatic Tuner along with the term "manual," and you may find a PDF version of the manual available for download.
3. Contact the manufacturer: If you're having trouble finding a manual for your tuner, you can contact the manufacturer directly. They may be able to provide you with a copy of the manual or direct you to a source where you can obtain one.
4. Consult with a music equipment dealer or technician: If you're still unable to find a manual for your Matrix Auto Chromatic Tuner, you can consult with a music equipment dealer or technician. They may have access to the manual or be able to assist you in operating the tuner without the manual.

I hope these tips are helpful in your search for a manual for your Matrix Auto Chromatic Tuner.

I have a Korg Concert Piano (C-15S) which was working perfectly till about two months ago. I have been on vacation for two months, had left the piano unplugged from the electric supply point, but on re-connecting now, I get no sound from it. Is there a reset button (or other device) that I may have to use? Appreciate your advice.

Thank you,

L. Paul
