I want to give you a real heads-up for your desire to enable such people as I to acquire the information I need to maintain the older types of equipment such as this Akai HXA351W. You do a swell job with all the processes you have to perform so I can have a legible, thus usable
document which does not send me crazy trying to figure out the blurry text of a bad copy.
Very well done, Thomas.

This manual is very well presented and after printing out looks about as close to an original as I think you can get. The quality is second to none.
The content of the manual is comprehensive and I think it would be well suited to an audio repair professional which I'm not but I did find it very informative and helpful.
The cost of the manual is more than covered by the money I'll save when I change the keep memory battery now I have the relavant info.
Very pleased with my purchase and can recommend it wholeheartedly as I can other manuals I've downloaded from this site.

Initial Reset Circuit When batteries are set or an AC adapter is connected, the reset IC provides a low pulse to the CPU. The CPU then initializes its internal circuit.

Power On/Off Circuit When the power switch is turned on, a low level differential pulse is provided to terminal MI of the CPU. Upon receipt of the pulse, the CPU starts the power ON sequence and raises the APO signal to +5 V. When the switch is off, on receiving the KO11 signal at terminal KI0, the CPU drops the APO signal to ground level to shut down power.
