SYSTEM DIAGRAM







SYSTEM DESCRIPTION

- The start up sound is a system that produces a sound that is linked with the power switch and with the
READY to drive indicator lamp on the combination meter.
- The start up sound function consists of the following 2 types.
- Power switch operation sound when the power switch is operated.
- READY effect sound that is linked to the READY to drive indicator lamp of the combination meter.
- A selection of 4 types (including OFF) of sound for the start up sound function is provided.
- The start up sound function sound types can be set using the combination meter.

POWER SWITCH OPERATION SOUND

The power switch operation sound is a function that operates when the power switch is pressed.
Operation Description
- The VSP control unit uses the power switch signal from the power switch to determine the power switch operation sound.
- When the VSP control unit inputs the power switch signal, the start up sound speaker signal is output to the start up sound speaker.
Operation Condition
When the following conditions are met, the power switch operation sound operates.





NOTE:
The power switch operation sound may not be able to respond normally if the power switch is pressed quickly.
Cancel Condition
The power switch operation sound stops when one of the following conditions is met.
- The power switch operation sound operation time is expired
- The READY effect sound operation condition is met
- The VSP system operation condition is met
Signal Path
- The VSP control unit judges operation of the power switch operation sound function based on the signal shown below, and it operates the power switch operation sound.





- When the VSP control unit judges that the power switch operation sound is necessary, it outputs the signal shown below.

READY EFFECT SOUND

The READY effect sound is a function that operates through a link with the READY to drive indicator lamp of the combination meter.
Operation Description
- The combination meter sends the READY to drive indicator lamp signal to the VSP control unit via the communication line.
- The VSP control unit determines the READY effect sound using the READY to drive indicator lamp signal from the combination meter.
- When the VSP control unit receives the READY to drive indicator lamp signal, the start up sound speaker signal is output to the start up sound speaker.
Operation Condition
When the following conditions are met, the READY effect sound operates.





Cancel Condition
When one of the following conditions is met, the READY effect sound operation stops.





Signal Path
- The VSP control unit judges operation of the READY effect sound function based on the signal shown below, and it operates the READY effect sound.





- When the VSP control unit judges that the READY effect sound is necessary, it outputs the signal shown below.
