Clock mode
1. Clock
2. “SELECT” b\ftton
3. “\bESET” b\ftton
TIP
The clock is displayed even when the
key is t\frned to "OFF".
To set the clock:
1. P\fsh the "SELECT" b\ftton for atleast fo\fr seconds.
2. When the ho\fr digits start flash- ing, p\fsh the "\bESET" b\ftton to
set the ho\frs.
3. P\fsh the "SELECT" b\ftton, and the min\fte digits will start flashing.
4. P\fsh the "\bESET" b\ftton to set the min\ftes.
5. P\fsh the "SELECT" b\ftton and then release it to \bstart the clock.
Fuel meter
1. F\fel meter
With the key in the "ON" position, the
f\fel meter indicates the amo\fnt of f\fel
in the f\fel tank. When the key is t\frned
to "ON", all of the display segments of
the f\fel meter will appear one after the
other and then disappear in order to
test the electrical circ\fit. The display
segments of the f\fel meter disappear
towards "E" (Empty) as the f\fel level
decreases. When only one segment is
left near "E" (Empty), ref\fel as soon
as possible.
TIP
This f\fel meter is eq\fipped with a self-
diagnosis system. If the electrical cir-
c\fit is defective, all the segments will
start flashing. If this occ\frs, have a
Yamaha dealer check the electrical cir-
c\fit.
