Acoustic signals



The SID unit can produce acoustic signals for various situations.

The signals are assigned priority as follows:


• Warning

• Time alarm (SID unit 3 only)

• Speed warning (SID unit 3 only)

• Reminder (warning, ignition key and seat-belt)

• Confirmation (of button depression)

• Direction indicators (TICK TACK)

The SID receives requests for acoustic signals from other systems on pins 16 and 17.
