play, water detection alert, engine trouble
alert, and periodic maintenance notification. If
the cooling water pressure sensor is installed,
the unit can also show the cooling water pres-
sure display. However, even if the cooling wa-
ter pressure sensor is not installed, the
cooling water pressure display can be shown
by connecting an optional sensor to the unit.
For the optional sensor, consult your Yamaha
dealer. The tachometer unit is available in
round or square types. Check your tachome-
ter unit type.
