Voltage display mode
This display shows the battery voltage.
"btry" appears for 1 second when the voltage
display mode is first selected, and then the
battery voltage is shown.
If the battery voltage is less than 10 volts, "LO"
is displayed and if the voltage is above 16
volts, "HI" is displayed.
NOTICE
If the voltage display indicates "LO" or
"HI", there may be trouble with the battery
charging circuit or the battery may be
faulty. If "LO" or "HI" appears in the dis-
play, have a Yamaha dealer check or repair
the vehicle.
