ALIGNMENT PROCEDURE
IDLE CURRENT ALIGNMENT (no load, no signal)
1. Connect a digital millivoltmeter between TP301 and TP303, and adjust P501 to
obtain a reading of between 30mV and 35mV.
2. Transfer the digital millivoltmeter to TP302 and TP304 and adjust P502 to obtain a
reading of between 30mV and 35mV.
3. Leave power on for at least 5 minutes to allow the idle currents to stabilize.
Re-adjust P501 and P502 as necessary to obtain a reading of between 30mV to
35mV on each channel.
