 Multiple Control Head Features 
ADVANCED FEATURES 
This feature allows a transceiver to control a combination of up to four O5 control heads on APX Mobile (depending on the 
model). 
 
You can use the CAN cables to connect in any configuration that does not exceed 131 feet (40 meters) in combined length. 
 
Refer the O5 Control Head Installation Manual (HLN6947) for further information. 
 
The Multiple Control Head (MCH) feature consists of 2 modes that can be programmed via Customer Programming Software 
(CPS):  
•  All Active mode 
•  One Active mode 
 
Note: If two or more control heads are connected to the system before enabling the MCH feature in the CPS, the radio will 
display EXTRA CH or CH ID # ERR. Both errors are FATAL.
