Multiple Control Head Features
Multiple Control Head Features
This feature allows a transceiver to control as many as four O5
control heads on APX 7500 and, up to two O5 control heads on
APX 6500. 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.

This feature allows you to setup the control head in the Front
Panel Programming (FPP) mode. During the setup, the control
heads are defined as Control Head Number 1, Control Head

emergency button simultaneously.
3 While continuing to depress these two buttons, press the
Power button to power on the radio and the control head.
4 The radio and the control head will power on into FPP
mode. The display shows control head’s ID number.

number.

mode.
