Adjustment method
<Adjustment method>
1.Set the volume control to minimum during this adjustment.(No signal & No load)
2.Set the surround mode OFF.
2.Turn VR787 and VR788 fully counterclockwise to warm up before adjustment.
If the heat sink is already warm from previous use the correct adjustment can not be made.
3.For L-ch,connect a DC voltmeter between B2204 and B2205 (Lch)
And,connect it between B2213 and B2214(Rch).
4.30 minutes later after power on, adjust VR787 for L-ch, or VR788 for R-ch so that the DC voltmeter
value has 1mV~10mV.

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, after you turn off amplifier and internal temperature falls.
* It is not abnormal though the idling current might not become 0mA even if it is finished to turn variable
resistance (VR787,VR788) in the direction of counterclockwise.

Self-diagnose function
1. Detection of abnormal power supply and voltage
When the power is turned ON, if an abnormality is detected during the signal input at the A/D port (IC901,
pin 2-5, 7) for one second continuously, the status will become STANDBY mode immediately.
When the power is turned ON again, detection of abnormal power supply and voltage will not be carried out
during the first 4 seconds.
Given below is a list of threshold values at the detection of abnormalities.
2. Initial setting on ship
To gain the initial setting on ship, put the power plug in the socket while pressing "DOWN" key and "UP" key
together simultaneously, then turn the power ON.
3. Test mode
To enter the test mode, put the power plug in the socket while pressing "EFFECT" key and "UP" key together
simultaneously, then turn the power ON.
Workings of test mode:
All FLs are turned ON for 3 seconds. (the FLs, which are divided in two groups, are turned ON alternatively)
A Faster volume UP/DOWN operation can be achieved with the remote controller.
When the power is turned OFF, the test mode will be released.
The FL display returns to normal after the three seconds. Then the STANDBY LED is turned ON (flashing
ON and OFF for each one second) to show the present status being a test mode.

To enter the self-diagnose mode, put the power plug in the socket while pressing "SETTING" key and "UP" key
together simultaneously, then turn the power ON.
While the working status is being displayed, the each item can be switched with the UP/DOWN key
operation.
When the power is turned OFF, the self-diagnose mode will be released.
During the self-diagnose mode, the STANDBY LED is turned ON (flashing ON for one second then OFF for
three seconds).
FL transient display will be carried out as follows. When the transient display is not carried out,
normal display/workings are carried out.
