1. Turn the key switch on lower left side to "LOCAL" position.
   Again, to emphasize: Please be careful not to overturn the key further to the "OFF" position!!
2. With the cursor keys (next to LCD display) select the desired HV channel number, then move to "Target_V"value of that channel.
   • Make a note of the current "Target_V" (target voltage) setting before you change anything.
3. It's highly recommended to DISABLE the channel before you change the settings.
4. Push the SELECT button (located below the cursor buttons).

6. Push the ENTER button (lower right of numerical keypad) to make the actual change.
7. Push the ENABLE button to switch the selected channel with the new HV setting.
8. If you like to change the target voltage again, repeat steps 3 - 7.
