Check contact with ohmmeter.
Measure resistance between
contact piece and shield tap.
With two terminating resistors the
measured resistance should be
25 Ω
ΩΩ
Ω.
Error :
Resistance = ∞
∞∞
∞ infinite
-> The contact piece or the clip
has not been tightened
sufficiently
Error:
Resistance = 0
-> Short circuit!
Remove chips from drilling

Attach transceiver to body.
Fasten with screws.
