3 Operating Instruction
The DC4104 is controlled by three buttons and the multicontrol knob on the front panel. The
two buttons below the graphics display have an Enter and Escape functionality. The button with
LED indicator is used to switch the LED on or off. The multicontrol is used to select the desired
menu or to change the settings.
After switching on the DC4104 a 'Welcome' screen appears for a few seconds.
In case no LED head is connected you will be prompted to switch off the main unit, connect the
LED head and switch on the device.
The display will show the screen of one of the three LED operation modes (Constant Current,
Brightness or External Control Mode). The 'Main Menu' can be accessed via the 'ESC' button.
To select an operation mode or a configuration display the multicontrol knob is used. Press the
'Ok' button to enter the selected item.
3.1 Operation Modes
For safety reasons the LED can be switched on only if one of the three operation modes (Con-
stant Current, Brightness or External Control) is selected.
It is possible to leave the active mode when the LED is switched on and enter the main menu.
However, the LED has to switch off before you can enter another operation mode. This can be
done while the main menu is selected by pressing the LED button.
The last selected operation mode will be saved. After switching on the DC4104 again this oper-
ation mode will be automatically restored. All settings are saved and validated after a shut off.
