Adjustable Support:
This can be clamped at any position on the slide of the mounting
bracket to provide pick-up height adjustment.
Pick-up holder:
This fits into the crutch of the pick-up support and is held in place by a
spring plunger. A biased holder, when used as shown in figure 3, exerts a biasing force on the
pick-up (depending on which way the holder is inserted into the support crutch). It can also be
used to position the pick-up directly underneath the display unit, as shown in figure 4.

Connector:
The connector of the pick-up lead is screwed into the end of the pick-up and
is then inserted into the end of the pick-up holder, with the lead coming out through the slot
