M7000D Halogen Illumination
The Swift M7000D base is equipped with a 12 volt, 20 watt illumination
system. The bulb for this illumination system is a Halogen type bulb with
approximately 200 hours of service. The time may vary depending on use,
intensity and brand of bulb used. To prolong the life of the bulb, you
should always turn off the unit when not in use and turn down the
dimmer switch when first turning the system on. This will prevent
unnecessary filament shock to the bulb resulting in a much longer life.
When purchasing replacement bulbs, it is important that you use only the
Swift approved bulb (Swift # MA781). This bulb has been tested and
approved for life span, color temperature and brightness.
NOTE: Use a piece of lens paper instead of your bare hand because
Halogen bulbs should never be handled. The oil from your hand will
contaminate the bulb’s glass envelope and cause it to fail almost
immediately.
To replace a bulb, you must first unplug the microscope. Remove the
eyepieces if they are not held in by screws and remove any slides on the
stage. Carefully turn the microscope on its side, unscrew and open the
illumination port. Make sure the bulb is cool and remove it by carefully
pulling the bulb out of its two prong socket. Insert the new bulb by
seating the bulb firmly into the socket. The bulb should not need further
alignment. Close the port door and secure firmly.
