Here is how you can assemble the collar and receiver:
1. Place the collar holes over the probe inserts. Be sure the receiver case is outside of the collar.
2. Place the plastic backstrip over the probe inserts.
3. Attach the posts by screwing them snugly into the receiver inserts.
NOTE: Be careful not to over-tighten the posts. Over-tightening can cause damage to the posts and the receiver case.
