Install the BZ-H adapter after the microphone, white bezel guide and dust cap are inserted into the bezel bore. The BZ-H adapter clamps to top of an installed Bezel to turn the cable path 90 when overhead clearance is too limited for normal vertical mounting of the Servoreeler®. Employing the BZ-H permits the Servoreeler® to be installed horizontally significantly reducing the required overhead clearance from about 16" total including connectors, to approximately 3". The BZ-H employs the same clamp that is used to install the Ceiling Bezel. This clamp is simply fitted to the top of the installed bezel, pushing it down onto the bezel body until it seats against its stop. Rotate the adapter so that the cable is aimed directly towards the cable exit point on the Servoreeler®; then tighten the Allen cap screw. The Servoreeler® must be installed so that the moving cable will not rub against any stationary surfaces; friction could impair normal Servoreeler® operation and this could also result in abrasion of the cable and eventually permanent damage to the cable jacket.
