With the AC line cord unplugged from the wall receptacle and with the AC power switch on the front of the unit in the
OFF position, plug the line cord into the AC inlet jack on the rear of the base. Exercise extreme caution from this point
forward, as potentially lethal line voltage will be present at various exposed points within the electrical base. Plug the
AC line cord into a properly grounded AC receptacle. The electronics may now be operated as necessary for
troubleshooting purposes. Never operate the microscope if the chassis bonding screw for the ground (center) pin of
the AC inlet jack is loose or missing, or if the wire to this lug is cut or damaged (see Figure 6). These are critical safety
components and are necessary to ensure that the chassis of the microscope is always at a safe potential in the event of
any electrical faults within the equipment.
