sions and use the DCM rotation/reach diagram below
as a guide to select the best mounting location that will
satisfy the following criteria:
4Easy access to utilities  cabinet must be
able to accommodate installation of utilities.
4Adequate mounting support  cabinet and
frame must be strong enough to support the
unit head with all accessories when the arms are
fully extended. NOTE: Additional mounting
support is recommended for cabinets constructed
of particle board or containing thin side walls.
4Proximity to dental chair  provide
