if defective. The circuit board is only replaceable at the factory.
6. Reassemble the unit by reversing the above procedures.
Connector Replacement
The Model 4308 is normally supplied with two Female TNC Bird Quick-Change
Connectors. Other “QC” connectors are available. These connectors may be obtained
from Bird Electronic Corporation. Refer to the Available Connector List.
These “QC” connectors are quickly changed by:
1. Remove the four 8-32 round head machine screws from the cor-
ners of the connector flange.
2. Pull the connector straight out.
3. Install connectors by reversing the above procedure. Making sure
the center contact pin aligns properly with the socket.
Element Removal
1. Remove the screw and sleeve on the lower left corner of the ele-
ment port flange.
2. Grasp the knurled part of the element knob in your fingers and
gently pull up while turning slightly in a clockwise direction. The
element will easily pull right out.
Element Installation
When reassembling the element in the line section, be sure the retaining clip on the front
face of the line section is repositioned. It must be on the shoulder of the element, before
replacing the retaining clip, stop-sleeve, and screw.
