Watercraft control functionsEJU43690Remote control transmitter
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 35 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.

The elapsed time will be kept even if the bat-
tery terminals have been disconnected.
EJU43751Voltmeter
The voltmeter shows the battery voltage.
When the battery voltage is normal, the volt-
meter displays approximately 12 volts.
If the battery voltage has dropped significant-
ly, “Lo” is displayed on the voltmeter, and the
information display, hour meter, and indicator
lights turn off. If the battery voltage has risen
significantly, “HI” is displayed. If “Lo” or “HI”
is displayed, immediately return to shore and
have a Yamaha dealer service the watercraft.
