To setup the unit, refer to Figures 4 and 5, and the legend table on the preceding page and
perform the following steps:
NOTE: For optimal performance a warm up time of at least 30 minutes is
recommended.
AC Line Voltage
The LCC25 is designed to operate at 100 to 240 VAC operation. There is no line switch
adjustment to be made. However it may be necessary to replace an open fuse. To do this
you must perform the following procedure on page 14, Fuse Replacement.
Powering ON the LCC25
•
Connect the appropriate power cord into the AC receptacle and plug the unit in.
•
Set power switch to the ON position. Thorlabs will scroll across the display.
Voltage 1, Voltage 2, and the Frequency then will be displayed.
•
BNC Output and External input LED indicators will be OFF. This is the default
state when the unit is power on.
Setting the Voltage and Modulation Frequency
There is a set of 6 buttons beneath the LCD display and a knob for adjustment to the left
of the display.
•
To change Voltage 1 press the VOLTAGE 1 key, the LCD top left will flash.
Adjust the knob to the desired Voltage.
•
To change Voltage 2 press the VOLTAGE 2 key, the LCD bottom left will
flash. Adjust the knob to the desired Voltage.

flash. Adjust the knob to the desired Frequency.
After pressing the key, the selected voltage or frequency can be saved by pressing the key
while the cursor is flashing or by letting the cursor time out in about 5 seconds. These
settings will be saved during power down and retrieved on power up.
