Yamaha Security System/
Low-RPM mode
This watercraft is equipped with a remote
control transmitter 1 that is used to select
the security system and low-RPM mode set-
tings. Since the watercraft is programmed to
recognize the internal code from this trans-
mitter only, the security system setting can
only be changed with this transmitter. If you
lose the remote control transmitter or it does
not operate properly, contact a Yamaha
dealer.
Yamaha Security System
The Yamaha Security System functions to
help prevent unauthorized use or theft of the
watercraft. The engine cannot be started if
the security system is in the lock mode. The
engine can only be started in the unlock
mode.
Yamaha Security System lock and
unlock modes
The lock and unlock modes of this system
can only be selected while the engine is
stopped.
When the lock button 2 is pressed, the
beeper sounds once. This indicates the lock
mode is selected and the engine cannot be
started.
