configured D1-528’s between or near  
the copy from and copy to D1-528’s.  
• INNCOMs room RF network is a Mesh  
network where messages initiated  
from one device “hop” from radio to  
radio in other nearby devices until  
they reach the intended target device.  
• If not many D1-528’s are installed yet,  
this could prevent the messages from  
the copy to D1-528 from reliably  
reaching the copy from D1-528 and  
continuing the room copy. You may  
need to wait until additional D1-528’s  
are installed so that a better mesh  
network exists.  
• Is there an RF interference source  
between the copy from and copy to  
D1-528’s? Like possibly a WiFi access  
point or other radio transmitter.  
• Is either D1-528 mounted on or near  
a metal object that could be shielding  
the RF signals from the D1-528’s? IF  
these is, is it possible to move/remove  
it or place the D1-528 at another  
location  
• There is a radio hardware issue in the  
D1-528 in either room. You can try  
swapping out the D1-528 in the copy  
to room with a new D1-528 and see if  
the room copy now works.  
• If none of the above applies, contact  
INNCOM Customer Service.
