DISCOVERY
ETM E6
CIRCUIT OPERATION
The audio system consists of a new head unit and
for mid/high range it is equipped with a subwoofer
and subwoofer amplifier. For mid and high range
the system also is equipped with a radio waveband
switch and a tune switch, a volume up and a
volume down switch which are located on the
fascia next to the instrument cluster.
The control head is equipped with an anti–theft
feature which makes the unit inoperative once
battery power is removed. A security code must be
entered to restore power to the unit. On every level
the system is equipped with two rear and two front
speakers.
Battery voltage is provided to the control head at all
times through the P wire. In addition to monitoring
the anti–theft feature, this input keeps the preset
station memory alive. Whenever battery power to
the unit is lost, the anti–theft code must be entered
and the preset stations must be reprogrammed.
When the Radio (Z111) and the ignition are turned
on, the voltage signal through the LGO wire and
the control head`wakes up' the unit. The Radio
(Z111) plays, the VF display comes on and the
control unit buttons illuminate. The VF display is
dimmed when the headlights or park lights are
turned on. When the lights are on, voltage from
fuse F8 of the Fascia Fusebox (P126) is applied to
the Radio (Z111) terminal 6, connector 230
signalling the Radio (Z111) to dim the display.
