@ Use of Service Mode
This is used to check external input (MD/CD2, PHONO) for
the amplifier by itself.
How to enter the service mode
1. With the plug pulled from the power outlet, short-circuit
(W275 and W276) the service terminal on the DISPLAY
Bore
DISPLAY Assy
CN2501
FL Tube
Oo
W276
W275
2. Maintain the condition of "1" and supply AC power.
The power will be switched on automatically and the
function will become MD/CD2. The present function status
will be displayed in the 7-segment time column of the front
FL.
3. After power ON, remove the terminal short-circuit bridge.
(Otherwise key operation can not be executed.)
4. The function status can be changed by body key operation.
The relation between key operation and FL display is
shown in Table 1.

and [CENTER MODE] operate normally.
Service mode cancellation
Switch off the power once and then switch is on again
normally. The function set in service mode remains memorized
until the plug is pulled out of the power outlet.
Notes)
1. Always use this mode only for the amplifier by itself.
(System operation does not operate normally.)
2. After cancellation of service mode according to the above
method, the FL indication becomes DISPLAY OFF mode
(the mode where the spectrum analyzer and the level
meter part are not displayed).
For display of spectrum analyzer and level meter, push
the [ + ] key of the unit in POWER-OFF condition to
switch the DISPLAY mode.
