It was magic after so many years to still be able to source this info. It was equally amazing to return my Pioneer receiver to it near new sound quality AFTER NEARLY 30 YEARS! Thank you for this ability!
Very quick and easy website to use and fast download of manual, quality of manual is excellent and will be pleased to use this service again in the future, thanks so much!
The manual is an excellent reproduction with complete schematics, made troubleshooting and repair a simple process.

Procedure : 1. Rotate the variable resistors RV105 and RV205 fully in the clockwise direction to minimize the idling current of the stabilized power supply. 2. The input signal is to be no signal. 3. Set the power voltage to +14.4 V, and turn the remote mode ON (Connect between the REM terminal and B+ terminal). 4. Adjust each of RV105 and RV205 so that the power current of the stabilized power supply is increased in steps of 500 mA for the XM-1502SX and in steps of 600 mA for the XM-1902GX.
