The T2004 Multi-Control Head system allows the use of between one and
five control heads with a single T2020 or T2040 radio. The control heads
are configured as one Primary and up to four Secondary. The Primary
control head is the only one which controls the radio's power, as well as
power to each Secondary control head, otherwise the functionality of all the
control heads is the same.
The remote control heads provide the same functionality as the standard
T2000 control head, except it does not provide for a DTMF module to be
fitted. If DTMF dialling capability is required, a T2000-A07 DTMF
microphone is required.
In addition, the remote control heads provide two extra functions:
Power Switch Selection (Primary/ Secondary mode selection
Global Mute
The Power Switch Selection function is provided so that only one control
head in the system (the Primary head) is able to control the system's power.
This function is selectable by the fitting of a jumper (JP2) on the control
head PCB of the Primary head. This is factory fitted by default.
Only the Primary head should have JP2 fitted. The system will not power
on correctly if more than one control head in the system has this jumper
fitted.
The Global Mute function is provided to avoid the possibility of audio
feedback when two or more control heads are placed in close proximity (for
example, within the same room or the same vehicle). The Global Mute
function is individually selectable on each control head, via a link on the
control head PCB. This is factory fitted by default.
If a control head has this jumper fitted, its speaker will only unmute when
the microphone is taken off hook (i.e. to answer or make a call). All other
