Halogen bulb replacement
Unplug the microscope from a power source. Loosen the knurled screw on the underside of the microscope and open the panel
to gain access to the lamp. Make sure the lamp has cooled down and then remove it. Do not touch the new lamp with your
fingers; fingerprints or dirt will reduce the brightness and the lamp's life. Use gloves to replace the lamp. If necessary, wipe the
lamp with a clean, soft cloth. Use a lamp of a suitable type. Insert the contacts into the slot vertically. Then, close the panel
and tighten the knurled screw finger tight.
Fuse replacement
Unplug the microscope from a power source. Open the fuse holder located on the back of the microscope body with a flat head
screwdriver. Remove the old fuse and install a new one. Only use the appropriate types of fuses. Close the fuse holder.
