There are two switches at the base of this unit to switch to the Hi-Current and Hi-Voltage modes respectively. When these two switches are not to set to the same modes, the Hi-Current and Hi-Voltage indicators on the top panel change from green to amber to indicate an error. "See INSTRUCTION MANUAL for more information."

Apply a 14.4V power supply voltage between the +12V and REMOTE terminals and GND terminal. 4. Adjustments Connect a digital voltmeter between the two terminals of the cement resistors R149 and R150 (0.03 ) indicated as TP101 and TP102 (TP201 and TP202 for R-CH). Rotate the semi-fixed resistor VR101 and adjust so that the voltage between TP101 and TP102 comes between 0.5 mV and 1.1 mV with 0.8 mV as the center. Adjust R-CH in the same way. · Perform adjustments carefully as voltage changes are minute. · When adjusting fr
