A wrong and too high LED current limit can cause damage to the LED. Prior
to changing the LED current limit check if the LED can handle this current!
LED Configuration
The LEDs maximum current can be reconfigured for LEDs with an EEPROM. This
value is valid until the DC2100 is restarted and can be changed in the 'User Limit
Current' menu.
This menu entry is hidden in normal operation mode. Go to the 'User Limit' screen
described above. Then press and hold the 'LED' button for about three seconds.
A sub menu appears and the LEDs maximum current can be set. Press the 'Ok'
button to select the 'Maximum Current Limit' menu. The multi-control knob is used to
change the value and has to be confirmed with the 'Ok' button or canceled with the
'ESC' button.

There is another menu item the 'Safety Mode' in the 'Settings' topic. The 'Safety
Mode' can be switched on or off. If it is enabled the LEDs can only be switched on
when one of the operating modes is selected. If the 'Safety Mode' is disabled the
LEDs can be switched on regardless which menu item is selected. The LEDs can
always be switched off independent of the 'Safety Mode'.
