The lightning flash with arrowhead 
symbol within an equilateral 
triangle is intended to alert the 
user to the presence of uninsulated 
“dangerous voltage” within the 
product’s enclosure that may be of 
sufficient magnitude to constitute a 
risk of shock to persons. 
The exclamation point within an 
equilateral triangle is intended to 
alert the user to the presence of important operating and maintenance 
(servicing) instructions in the literature accompanying the product. 
•  Finish out the dmc1 system after the application of wall covering 
material. 
•  Do not power up the dmc1 master until all remote stations and 
speakers are connected. 
•  Do not connect a CAT-5 wire if you are unsure of it terminating 
point. Connecting a door speaker to a room station may result in 
system damage. 
•  Do ensure that all rough-in instructions have been followed before 
power is applied to the dmc1 system. 
•  Do not splice cables. Splices are unreliable and defeat the signal 
isolation properties of the cable. 
•  Do not attach devices unauthorized for use with this system. 
Authorized devices include: 
•  Audio components connected via a line level input 
•  DMC1CD 6-disc player 
•  If extra cables have been run for future speaker additions, care 
must be taken to ensure these cables are not connected to the 
dmc1 master unit. Un-terminated cables (no station) connected to 
the dmc1 master may cause electronic feedback that will damage 
the master unit.
