UVP TB-101 Selector Switch - Manual (Page 5)

Installation Procedure
1. Looking at the front of the replacement selector switch, note the position of the alignment
tab. When installing the new switch, this tab should be aligned with the alignment hole in the
body of the transilluminator (see illustration).
2. Place the lock washer over the shank of the replacement selector switch.
3. Flexing the front of the reflective panel toward the rear of the transilluminator, insert the
selector switch into the opening in the body of the transilluminator so that the alignment tab
and selector switch shank fit through the correct holes.
Note: Ensure that the alignment tab is inserted into the small hole above the opening for the
selector switch shank. Also, ensure that the lock washer is in place between the body of the
selector switch and the body of the transilluminator.
