ADJUSTMENT PRECAUTION
The model is a mixture of the adjustment items of I
2
C BUS-CONTROL and the existing analog
adjustment. Moreover, since the adjustment with I
2
C BUS-CONTROL is composed of the items
which are set with the initial values (preset values) alone and the data variable items, refer to the
following.
1) Setting method to the microprocessor service mode
1 When the jumpers 351 and 352 of SET UP are short-circuited, enter into the service
mode (I
2
C BUS CONTROL adjustment mode).
2 The modes can be sequentially selected with the CH DOWN key of R/C.
3 The modes can be sequentially selected in the reversed order of 2 with the CH UP key
of R/C.
4 The data can be converted with the VOLUME UP/DOWN key of R/C.
5 When the short circuit between the jumpers 351 and 352 of the setup is cut off, it will be
released from the service mode.
2) Initial value (preset value) setting
1 When the MAIN POWER switch set at the service mode side is turned on, the initial
value will be automatically set only on the new E
2
PROM (discriminated with the head 4
bytes).
2 The initial data is set as shown in the attached sheets.
3 Take care that there are the items which need be changed and the items in which the
initial values continue set.
