Multiple Control Head Features 
One Active Mode 
103 
The One Active mode enables only one control head to be visibly active at a time in a two control head 
system. 
 
Note: In the One Active mode, if more than two control heads are present upon power up, the radio shows a 
FATAL error Extra CH on the display of all attached control heads. 
 
The active control head commands the system normally while the inactive control head is in remote mode with 
its display shows Remote. 
The Volume knob, DIM button, Front/Rear (F/R) soft-key, Emergency, Emergency Footswitch, and VIP 
inputs remain active on the inactive control head, while all other controls are disabled.  
The VIP input control head is configurable in the CPS and VIP should be attached to the control head selected 
in the CPS.
