Why am I getting a long beep on my Sea-doo Boat when using the safety lanyard?
A long beep when installing the safety lanyard on the DESS post or pressing the start/stop button on your Sea-doo Boat can indicate a bad connection between the safety lanyard cap and the DESS post. Try removing and reinstalling the safety lanyard on the DESS post; you should hear two short beeps, indicating the system is ready. It could also indicate that you are using the wrong safety lanyard; ensure you are using the lanyard programmed for the boat. If it doesn't work, contact an authorized dealer. Also, dried salt water or oil in the safety lanyard cap can cause this issue; clean the safety lanyard cap with dishwashing liquid.
What to do if I hear 4 short beeps on my Sea-doo Boat when starting?
Four short beeps when pressing the start/stop button with the safety lanyard already installed on your Sea-doo Boat indicates that the shifter is not in neutral. Place the shifter in neutral; you should hear one short beep when you reach the neutral position.
What does 2 short beeps mean on Sea-doo Sportster 1998 Boat?
If you hear two short beeps while installing the safety lanyard on the DESS post of your Sea-doo Boat, the engine can be started normally.
