Adjustment of idling current
Attention
This adjustment does not obtain a correct adjustment value immediately after the amplifier is
used (state that an internal temperature has risen).
Please adjust immediately after using the amplifier after turning off the power supply of the
amplifier and falling an internal temperature.
* It is not abnormal though the idling current might not become 0mA even if it is finished to turn variable
resistance (VR701, VR702, VR751, VR752, VR771, VR772, VR801) in the direction of counterclockwise.

<Adjustment method>
Prior to turning the power ON, fully turn the adjusting resistor (VR701, VR702, VR751, VR752, VR771,
VR772, VR801) counterclockwise direction and connect the DC voltmeter to the measuring terminal (B901-
B902, B903-B904, B905-B906, B907-B908, B909-B910, B911-B912, B913-B914).
Adjust the resistor so that the measured value becomes 2.0mV just after the power supply is turned on.
Adjust the resistor so that the measured value becomes 2.5mV more than 60 seconds after the power supply
is turned on.
After stability is 1.0-4.0mV.
The "idling current" graph of the following page is referred to.
