Mount the Extension ringer
•  You will need to purchase the following items 
separately to mount your Extension ringer.
•  The types of screws and anchors you need 
depend on the composition of the wall.

parallel. Make sure they are the same 
distance apart as the wall mount holes on 
the Extension ringer.
•  Check for signal strength before 
drilling the holes.
2.  Drill two holes in the wall (7/32” drill bit).
•  If you drill the holes into an object 
other than a stud, insert the wall 
anchors into the holes and tap gently 
on the ends with a hammer until the 
wall anchors are flush with the wall.
