Watercraft control functionsEJU43690Remote control transmitter
(VX Deluxe / VX Cruiser / VX Limited)
The Yamaha Security System and Low RPM
Mode settings can be selected by operating
the remote control transmitter. (See page 26
for Yamaha Security System setting proce-
dures and page 33 for Low RPM Mode acti-
vation procedures.)
Since the watercraft is programmed to rec-
ognize the internal code from this transmitter
only, the settings can only be selected with
this transmitter.
If you accidentally lose your remote control
transmitter or if it is not operating properly,
contact a Yamaha dealer.
When operating the watercraft, always keep
the transmitter with you, such as by storing itin the transmitter holder in the glove compart-
ment, so that it is not lost.
NOTICE
ECJ00753

completely waterproof. Do not sub-
merge the transmitter or operate it un-
derwater. If the transmitter is
submerged, dry it with a soft, dry cloth,

gent, alcohol, or other chemicals.
Do not attempt to disassemble the re-
mote control transmitter yourself. Oth-
erwise, the transmitter may not operate

VX Cruiser / VX Limited)
The Yamaha Security System functions to
help prevent unauthorized use or theft of the
watercraft. The lock and unlock modes of the
security system can be selected by operating
the remote control transmitter that is included
with this watercraft. The engine cannot be
started if the lock mode of the security sys-
tem is selected. The engine can only be start-
ed if the unlock mode is selected. (See page
25 for information on the remote control
transmitter.)
TIP:
The Yamaha Security System settings can
only be selected while the engine is stopped.
EJU36776Yamaha Security System settings
The Yamaha Security System settings will be
confirmed by the number of beeps when the
remote control transmitter is operated, and
by the “UNLOCK” indicator light of the multi-
function information center. (See page 38 for
information on the multifunction information
center.)
TIP:
The beeper sounds two times for the nor-
mal operation mode or three times for the
Low RPM Mode. (See page 33 for Low
RPM Mode activation procedures.)
If the remote control transmitter is operated
while the multifunction information center
is in the standby state, the center will per-
form the initial operation, and then the set-
ting is selected.
To select the lock mode:
Push the lock button on the remote control
transmitter briefly. The beeper sounds once
and the “UNLOCK” indicator light blinks
once, then goes off. This indicates the lock
mode is selected.
To select the unlock mode:
Push the “L-Mode” (unlock) button on the re-
mote control transmitter briefly. The beeper
sounds two or three times and the “UN-
LOCK” indicator light blinks two or three
times, then comes on. This indicates the un-
lock mode is selected.
