LED REPLACEMENT
The SILVER250 Series is equipped with a 3 watt LED illumination system. The life of the LED
may vary depending on use and intensity. To prolong the life of the LED, you should always
turn off the unit when not in use. It is important that you only use a Motic replacement LED
because it is integrated on to a circuit board. This LED has been tested and approved for life
span, color temperature and brightness.
Make sure the microscope is unplugged before replacing the LED.
• Remove the eyepiece(s) from the head if they are not secured in place so they do not
accidently fall out of the microscope. Remove the slide that may be on the stage.
• Turn the microscope on its side. Remove the 4 screws on the bottom of the microscope.
Remove the base cover to access the LED.
• The LED is integrated on to a circuit board. This LED circuit board is held into the illumina-
tor housing by 2 screws. Remove the 2 screws from the illuminator housing to remove the
LED circuit board.
• Unplug the LED’s power wire from the circuit board attached to the base .
• Reverse the steps listed above to install the new LED.
