All Active Mode; Intercom Feature; One Active Mode - Motorola APX 7500 O5 User Manual

All Active Mode

The All Active mode enables all connected control heads of the
radio to operate concurrently with each other. When you
activate a feature on one control head, the rest of the control
heads will have the same activated feature and indicator on
their respective display.
The multiple control head feature allows only control heads of
the same type to be connected. Upon power up, if a control
head of a different type is connected to the radio, the radio
reports the fatal error CH MISMATCH on the display of all
attached control heads.

meantime, the inactive control head is in remote mode with its
display showing REMOTE.
The Volume knob, DIM, Front/Rear (F/R) softkey and
Emergency buttons remain active on the inactive head, while
all other controls are disabled. Emergency footswitch and VIP
inputs are also still active on the inactive control head. However,
VIP inputs must be connected to the head assigned ID #1.
