When the ignition switch is in the RUN or the ACCY position,
the electronically tuned radio receives power from the following components:
| • | The RADIO ACCESSORY fuse |
The clock and the memory circuits receive power from the RADIO BATTERY
fuse at all times. The radio is grounded through CKT 151. When the
ignition switch is in the RUN or the ACCY position, the vacuum fluorescent
display illuminates in order to display the following features:
| • | The radio frequency setting |
The panel dimmer switch controls the radio illumination. When the headlamp
switch is in the PARK or the HEAD position, voltage is applied through the
panel dimmer switch and CKT 8 to the following components:
When the headlamp switch is in the PARK or the HEAD position, voltage
is applied through CKT 9 to the radio. This condition signals the
internal circuitry to adjust the brightness of the vacuum fluorescent display
to a level determined by the voltage of CKT 8.
Remote Cassette Tape Player (Optional)
Voltage is supplied to the cassette player through the radio under the
following conditions:
| • | The ignition switch is turned to the RUN or the ACCY position. |
| • | The radio power switch is in the ON position. |
When the remote cassette player is in the PLAY position, the cassette
player returns a tape ON signal and the stereo audio signals to the radio.
The tape ON signal causes the following actions to occur:
| • | The receiver circuitry ignores the signals from the tuner. |
| • | The receiver circuitry sends the audio signals from the cassette
player to the speakers. |
The cassette player applies a mute signal to the radio in order prevent
the audio sound of the following functions from being heard:
When the EJECT button is pushed on the cassette player, the following
actions occur:
| • | The tape ON signal terminates. |
| • | The radio returns to normal operation. |
