MODE
TIP
• Measurement using the timer function can be
made in RACE MODE.
• Indicator will light up as an identifier that
shows RACE MODE has been selected.
• RACE MODE cannot display the functions as
in BASIC MODE.
• Changeover to RACE MODE forces the digits
for tripmeter A (TRIP A) in BASIC MODE to be
reset.
Changeover from BASIC MODE to RACE
MODE
1. Push the “SLCT1” button and “SLCT2” but-
ton for 2 seconds or more at the same time
to change over to RACE MODE.

3. Run the machine and start timer measure-
ment.
4. To stop timer measurement, pushing the
“SLCT1” button and “SLCT2” button at the
same time.
TIP
If the machine is run while timer measurement
is not made, no change will occur to the digit in
tripmeter A (TRIP A).
5. To resume the measurement, again pushing
the “SLCT1” button and “SLCT2” button at
the same time.
Resetting measurement data
TIP
Resetting can be made in the following two
manners.
Resetting is possible while timer measurement
is made:
• Reset tripmeter A.
Resetting is possible while timer measurement
is not made:
• Reset tripmeter A and timer.Resetting tripmeter A (TRIP A)
1. Check that the timer is in operation. If the
timer is not in operation, start the timer by
pushing the “SLCT1” button and “SLCT2”
button at the same time.
2. Reset tripmeter A (TRIP A) display by push-
ing the “RST” button for 2 seconds or more.
TIP
If reset, and travel distance display will go on
flashing for four seconds.
Resetting tripmeter A (TRIP A) and timer
1. Check that the timer is not in operation. If the
timer is in operation, stop it by pushing the
“SLCT1” button and “SLCT2” button at the
same time.
2. Reset all measured data by pushing the
“RST” button for 2 seconds or more.
TIP
• Resetting will reset the timer display and trav-
el distance display and put measurement on
standby.
• Auto start attempt will put measurement on
standby as such. Likewise, manual start at-
tempt will put measurement on standby as
such.
