Very complete and well reading drawings. Documentation is essential for successful repairs.Good documentation, with all that is necessary. This manual was what I was waiting with all the information necessary for the repairing I need it for. You must buy it if you want to do repairs or simply understand how it works.

XM-2150GSX SECTION 3 ELECTRICAL ADJUSTMENT
Bias Adjustment
Note : In Bias Adjustment, adjust RV105 if any of Q108 through Q113 are replaced. Adjust RV205 if any of Q208 through Q213 are replaced. Condition : This adjustment should be performed about one minute after the remote mode is turned on at a room temperature of about 25°C. Setting :
B+, REM terminal
set Stabilized Power supply GND terminal
Procedure : 1. Turn the variable resistors RV105 (L-CH) and RV205 (R-CH) full clockwise as seen from the component side to minimize the bias current. 2. The input signal is to be no signal. 3. Apply the voltage to the B+ and REM terminals from the stabilized power supply and gradually increase it up to 14.4 V while checking for any unusual current. 4. Adjust each of RV105 (L-CH) and RV205 (R-CH) so that the power current of the stabilized power supply is increased in steps of 500 mA (total of 1 A). 5. After adjustment, check that the power current is at 1.3 to 2.0 A.
