ADJUSTMENT PRECAUTION
The model is a mixture of the adjustment items of I2C BUS-CONTROL and the existing analog adjustment. Moreover, since the adjustment with I 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 (I2C 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 E2PROM (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.
