The I/P dimmer switch controls the following components:
| • | The brightness of the incandescent lamps |
| • | The Vacuum Fluorescent (VF) displays |
The incandescent lamps are located in various components. The VF displays
are located in the radio.
Incandescent Dimming
A variable voltage signal produced by the I/P dimmer switch determines
the brightness of the incandescent lamps.
Vacuum Fluorescent (VF) Dimming
The VF dimming signal controls the brightness of the VF displays. The
VF display of the radio will dim for low light viewing with the park lamps
ON. The VF displays are at high brightness for daytime viewing with
the park lamps OFF. When the park lamps are ON, the I/P lamp dimmer switch
provides a signal (VF Dimming Signal CKT 230) which controls
the brightness of the VF displays when the I/P dimmer switch is adjusted.
Park Lamp Dimming
When the park lamps are ON, the park lamps on signal (CKT 308)
applies to the following components resulting in the dimming of the components
for night time viewing:
| • | The heater and A/C control (CJ2) |
