(1) Application
Perform this work whenever you replace the MAN-H/MAN circuit board on which the EEPROM is mounted. Create a backup file of the data in EEPROM to be replaced in a PC, and write the backup file to new EEPROM: Some adjustment items that are performed after replacement can be omitted. Refer to "6-3-2 List of Adjustments Needed After Replacing Major Components" for adjustment items that can be omitted.
(2) Preparations
1) Connect the VDR-M70PP/M50PP, jig/tool and power supply as shown in Fig. 4-9-3. Refer to "6-1-1 List of Jigs and Tools used when Creating Reference Data" and "6-1-2 Power Supply and Materials for Creating Reference Data" for details on jig/tool and power supply in the figure. 2) Copy the adjustment program to HDD of PC. Refer to "6-1-5 Copy or Deleting Adjustment Program" for copying. 3) Start the adjustment program in order to display the adjustment menu screen on PC display.
Prohibition:
Completely assemble the VDR-M70PP/M50PP; create backup file of EEPROM data and write it with only the adjustment cover removed (see Fig. 4-9-3). Do not attempt to perform work with the VDR-M70PP/M50PP disassembled: Doing so is very dangerous because the VDR-M70PP/M50PP incorporates high-voltage circuits and a laser emitter block. Note: 1) Always connect the Skylark connection jig before connecting the DC power cord to VDR-M70PP/ M50PP: Connecting the Skylark connection jig after powering the VDR-M70PP/M50PP could cause a fault. 2) Connect the Skylark connection jig so that the lead wires from jig face up.
