KEEP cables away from objects such as heating and air conditioning
ducts, metal construction plates, and anything else with sharp
edges that can damage the cables.
Cautions: Room Station Rough-In
Careful consideration should be used when determining the location of
the room stations and master. Since this is a retrofit system you will
not be able to control the location of the existing system. But please
follow the guidelines below if you install any new locations:
DO NOT install room stations in return air ducts.
DO NOT install room stations in exterior walls. Insulation materials
will change speaker range and efficiency. Temperature changes in
the wall will reduce speaker life.
DO NOT install room stations in saunas. They will not withstand the
extreme heat and moisture.
DO NOT install room stations underneath cabinets or over counter
tops.
DO NOT install room stations in stud cavities with other wiring or
appliances.
DO NOT install room stations within 18” of dimmers, fluorescent
light fixtures, security wiring, cordless phone units, and other
control wiring.
DO NOT install room stations within 10 feet of other room stations
or the dmc3-4 master unit. This will cause acoustic feedback.
DO NOT install room stations in stud cavities with other room
stations or the dmc3-4 master unit. This will cause acoustic
feedback.
DO NOT install room stations facing other room stations or the
dmc3-4 master unit. This will cause acoustic feedback.
DO make sure all mounting rings are level and oriented as shown in
these instructions.
