Quality scan of the original. All the detail necessary to troubleshoot, repair and adjust the unit. I'm sure I will be downloading more manuals in the future as the need arises.

Exactly as described, a Service Manual complete with the schematics and PCB layout delivered in a timely manner. Many thanks for the great service.

some of the writing is a bit blur but the part in the schmatic was great and i have fixed the machine thanks

Well.. I'd searched for this manual and although I found many copies online I was pleased to find your website with a well balanced pricing system and easy to search and follow links. That together with the very quick response time was just what I was looking for.. being a very impatient tech.. ;-) I had the service manual in front of me within a short time.
Bookmarked.. and you can bet I will always come here first for my service & user manuals..
best regards

Caution Be sure to remove only one battery at a time. Otherwise, you will lose all data stored in memory.
3) Replace the old battery with a new one, making sure that the positive (+) side of the new battery is facing up (so you can see it).

Replace the battery holder and secure it by tightening its screw. � Be sure careful that you do not over tighten the screw. Repeat steps 2) through 4) for the other two batteries. � Be sure to replace all two batteries. Never mix old batteries with new ones, and be sure to use CR2032 lithium batteries only.
