Thanks to this service manual I repaired my old camcorder! The manual perfectly explains how to disassemble the camcorder step by step.
;
This manual is very useful because it presents the technical specifications of the cd player, including the manufacturer of the reader, this helps if you need to replace it. It also displays the settings and layout of the circuit.
;
Manual was a good representation of service infomation for the EWV404. It worked well for my repair.
 ;
Great quality copy, right what I was looking for, all I need to fix my radio.
Thanks

I BOUGHT A PAIR OF INFINITY VINTAGE SPEAKERS THAT REQUIRED TO BE REPAIRED AND THE ELECTRONIC TECHNICIAN ASKED ME FOR THE SERVICE MANUAL.
I TRIED TO GET IT AT THE MANUFACTURER'S SITE WITH NO SUCCESS, SO I STARTED TO LOOK FOR IT IN THE WEB FOR A LONG TIME, UNTIL I FOUND THE SERVICE MANUAL IN THIS EXCELLENT SITE "OWNER'S MANUAL.COM".
NOW I HAVE MY SPEAKERS WORKING AND ENJOYING THE MUSIC I LIKE.
THANKS TO "OWNER`S MANUAL.COM" I RECOMMEND THIS SITE TO EVERYONE.

Mnemonic DATEN
Description Data Enable Low Input. This port controls the 8-bit parallel data latch and shift register. A Logic 0-to-1 transition transfers the latched data to the attenuator core (updates the gain) and simultaneously inhibits serial data transfer into the register. A 1-to-0 transition inhibits the data latch (holds the previous gain state) and simultaneously enables the register for serial data load. Serial Data Input. This digital input allows for an 8-bit serial (gain) word to be loaded into the internal register with the MSB (Most Significant Bit) first. Clock Input. The clock port controls the serial attenuator data transfer rate to the 8-bit masterslave register. A Logic 0-to-1 transition latches the data bit and a 1-to-0 transfers the data bit to the slave. This requires the input serial data word to be valid at or before this clock transition. Common External Ground Reference.

Common Positive External Supply Voltage. A 0.1 F capacitor must decouple each pin. Logic �0� powers down the part. Logic �1� powers up the part. Low Power Sleep Mode. In the Sleep mode, the AD8323�s supply current is reduced to 4 mA. A Logic �0� powers down the part (High Z OUT State) and a Logic �1� powers up the part. Negative Output Signal. Positive Output Signal. Internal Bypass. This pin must be externally ac-coupled (0.1 F cap). Noninverting Input. DC-biased to approximately V CC /2. For single-ended inverting operation, use a 0.1 F decoupling capacitor and a 39.2 resistor between V and ground. IN+ Inverting Input. DC-biased to approximately V CC /2. Should be ac-coupled with a 0.1 F capacitor.
