[Preparation for Preset Data Writing, Battery Down Adjustment, and Charge Threshold Level Adjustment] 1 �Preset Data Writing�, �Battery Down Adjustment�, �Charge Threshold Level Adjustment� and all adjustments of �Video Block� must be performed, if IC901 (EEPROM) on the YM-11 was replaced. 2 �Battery Down Adjustment� and �Charge Threshold Level Adjustment� must be performed, if IC902 (5 V REG.) or IC903 (microprocessor) on the YM-11 was replaced. 3 All adjustments of �Video Block� must be performed, if IC101 (OSD), IC103 (Y/C separation), IC201 (Y/R-Y/B-Y decoder) on the YM-11 board, or IC401 (LCD driver) on the RG-46 board, or LCD (optical block) was replaced. 1.

2. Adjusting Remote Commander For the adjustment, the adjustment data saved in the nonvolatile memory (EEPROM) must be rewritten, and for this purpose the adjusting remote commander is used. The adjusting remote commander makes two-way communication with the product using a remote control signal line (LANC). The adjusting remote commander transmits pages, addresses, and data up/down commands to the product. The product transmits pages, addresses, and data to the adjusting remote commander.

3. How to Use Adjusting Remote Commander (1) Connect the adjusting remote commander to the CN902 on YM11 board via extension cable (J-6082-291A). At this time, set the switch of extension cable to OFF (OPEN) position. Turn ON the power on the set. (2) Set the HOLD switch on the adjusting remote commander to the HOLD (SERVICE) position. If connection is normal, the LCD display on the adjusting remote commander will be as shown in Fig.3-2.
