Great manual...really saved me. The only problem is that I thought I would be able to download it directly when I paid for it but never received the download instructions until the next morning. The board trace pages were somewhat light also: really need to turn up the contrast on the printer before printing them. The schematic page was great; very clear! Well worth the money.

I've been in the electronic business for a long time. I used to buy Sam's Photofact for my needs which intailed having to go to the store and paying about $20 for a package of 3 different units so I was forced to buy more than I needed just to get one.
Owner manual is just at your keyboard and the information is almost instantansouly and the cost is very reasonable. Easy to print out if needed or simply read off of the screen. The larger the screen the better for obvious reasons.

Very good manual, at a very good price. Received in a timely manner

Only thу cover has poor quality, internal material has excellent quality - exactly what I needed
Thanks!

â� ADJUSTMENT
Item Noise convergence Clock accuracy Procedure 1. Input a 98.1MHz/55dB(1kHz,30% MOD)signal.(0dB=1.4V) 2. Adjust the output to �18±3dB by VR102 when the SSG output is set �20dBμ. 1. Turn off and on the ACC switch,while holding CD EJECT button and POWER button.Repeat it twice slowly. 2. Set a universal timer to TP201,adjust TC201 so that a reading of the meter is 0±0.1 sec/day.
