Figure 8-5 Removing the Receiver
8.5.2 Replacement
To replace Receiver CTR21 (Note Paragraph 8.3 Start-up procedure):
1. Attach the Coaxial Cable to connector J2 at the receiver. Note the marked
ends of the cable.
2. Take the Receiver into your hand and set it in place. Note the right
position, the ribbon and coaxial cables come out from the back side.
Rotate the attachment ring (Figure 8-5) first by hand and then tighten it
using a 2.5 mm hexagon key as a lever. If the receiver begins to move
along, carefully stop that by hand. Do not apply force to the receiver
itself because it may disturb the centering.
