Fig.1 Charged Section and High Voltage Generating Point (Rear View)
Charged Section
The places where the commercial AC power is used without
passing through the power supply transformer.
If the places are touched, there is a risk of electric shock. In
addition, the measuring equipment can be damaged if it is
connected to the GND of the charged section and the GND of the
non-charged section while connecting the set directly to the
commercial AC power supply. Therefore, be sure to connect the
set via an insulated transformer and supply the current.

High Voltage Generating Point
The places where voltage is 100V or more except for the charged
places described above. If the places are touched, there is a risk of
electric shock.

Discharge the VSUS voltage, as shown below:
[Method for discharging the VSUS voltage]
1. Set DRF_SW on the DIGITAL VIDEO Assy to ON (Drive
OFF status). *1, 2
2. Leave the switch at that position for about 20-30 seconds.
3. If the power is on, turn it off. Then return DRF_SW to the OFF
position. *3
Notes
*1: You can also set the unit to "Drive OFF status" by sending the
"DRF" RS232C command from the PC.
*2: DRF_SW can be switched whether the power is on or off.
*3: Power-down will occur if DRF_SW is set to OFF while the
power is on. (See "7.1.6 Power on/off function for the large-
signal system".)
