Care and maintenance

Replacing the transmitted light unit bulb
1. Use the ON/OFF switch (fig. 1, 5) to turn the microscope off and then
remove the power plug.
2. Undo the clamping screw to open the housing and then remove the
glass plate and blue filter. The bulb (fig. 4) and its mounting are now
visible.
3. Carefully remove the old bulb from its socket.
4. Insert the new one carefully. Make sure the bulb is correctly inserted.
5. Clean it with a little alcohol to remove any fingerprints.
6. Then close the housing. The microscope is then again ready for use.
Changing the bulb in the direct light unit
1. Use the ON/OFF switch (fig. 1, 5) to switch the microscope off and
unplug it.
2. To make the job easier remove the entire lens unit. This is done by
undoing the clamping screw (fig. 1, 16). Then put the entire unit
carefully aside.
3. Then carefully unscrew the filter mounting with filter. Make sure the
filter doesn't fall out (fig. 4).
4. Carefully remove the old bulb from its socket.
5. Insert the new one carefully. Make sure the bulb is correctly inserted.
6. Screw the filter back on and fasten the entire until back in place. The
microscope is then again ready for use.
Changing the fuse
Two fuses are inbuilt to protect the microscope. Should
one fail it can be changed as follows.
1. Turn the microscope off using the ON/OFF switch (fig. 1, 5) and then
remove the plug.
2. Check which fuse needs replacing. To do so undo the fuse caps on
the microscope back. This is best done using a coin.
3. Then check them both. The wire in either or both is often visibly
broken. If so, then that fuse must be replaced. Alternatively, switch
the fuses around to find out which is not functioning.
4. Your microscope is ready for use again once any defective fuse has
been replaced.
Keeping the lens clean
Cover the microscope when not in use using the hood supplied to keep
it clean.
Your microscope is a precision instrument so please do not remove
any part/s of it. Doing so may prevent it working properly.
