Yamaha 115 3 beep alarm

[paulcuc]

I have twin 2006 yamaha 115txr 4 strokes that give me a 3 beep alarm when I turn the ignition keys to on before starting the motors . Both motors do the same thing. The alarm clears when the motors are started and I have tested the emergency stop lanyard switch and get a single beep.
I don't have an owners maunual so any info on the alarm meanings would be helpful.

The twin engine switch panel has a self test function that will beep the buzzer when first turn key on.
