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..
I will definitely be back for more information when I need it.

Replacing Q22 (FET TX final)
1. Place Q22 in its location, upside down as shown in figure 1. Make sure the location of each pin is correct. The bevelled edge is located between pin 1 and 2. (See the figure below) Replace the heat conductor sheet (G11-2664-x4) when replacing Q22. TX-RX UNIT A/3 Foil side

2. The bottom surface of Q22 must be firmly contacted to the TX-RX PCB. Solder each pin onto the top of the metal posts. Make sure the solder is between the pin and the metal post (Refer to figure 2). 2. Q22çåºé¨è¡¨é¢å¿
â¢ Make sure you are properly grounded while soldering the Q22. â¢ Avoid adding excess solder to the metal post. â¢ Make sure the bottom surface of Q22 is firmly contacted to the TX-RX PCB. â¢ The metal posts for the pins are also soldered to the PCB. So, when you solder the Q22 pins to the metal posts, keep the soldering time as short as possible so that the posts are not moved.
