In the real mode, the mode changed to the setup mode by pressing ▲switch and ▼switch at the same
time for more than 2 seconds. In the setup mode, the peak and warning LEDs in the gauge blinks alter-
nately. And the gauge pointer points the number of cylinders. The buzzer bleeps. Set up the number
of cylinders and the buzzer on/off in the setup mode. The mode returns to the real mode automatically
when any switch is not pressed for more than 5 seconds.
In the setup mode, the setup of the number of cylinders changes every time ▼switch is pressed(4→3→
2→1→8→6→5→4→・・・(repeat). Match the number on the gauge dial and the number of cylinders of
your vehicle.
The mode returns to the real mode automatically when any switch is not pressed for more than 5 sec-
onds.
Set whether to turn the buzzer on or off when warning SET2 is exceeded.
In the setup mode, the buzzer is turned on/off by pressing ▲switch. If the buzzer is set on, it bleeps
(short beeps) in time with blinking of the peak and warning LEDs. If the buzzer is set off, it does not
sound.
If the buzzer is set on, it feeps (a long beep) when the RPM exceeds the warning SET2 in the real
mode. If the buzzer is set off, it does not sound.
The mode returns to the real mode automatically when any switch is not pressed for more than 5 sec-
onds.
※The buzzer sounds when switches are pressed. It cannot be turned off.
Two warning RPMs can be set at SET1 and SET2. Set the SET2 RPM higher than the SET1 RPM. The factory setting is
at 6000rpm(SET1) and 7000rpm(SET2). Change the RPMs as you like.
※Even if the battery is disconnected, the setting is not cleared.
In the real mode, the mode changes to the warning setup mode SET1 if ▼switch is pressed for more
than 2 seconds. In the warning setup mode SET1, the warning LED blinks as follows:
In the real mode, the mode changes to the warning setup mode SET2 if ▲switch is pressed for more
than 2 seconds. In the warning setup mode SET2, the warning LED blinks as follows:
To raise the set RPM of the warning, press ▲switch. Every time ▲switch is pressed, the set RPM is
raised in degree. If ▲switch is pressed long, the set RPM is raised faster. To lower the set RPM of the
warning, press ▼switch. Every time ▼switch is pressed, the set RPM is lowered in degree. If ▼switch is
pressed long, the set RPM is lowered faster.
The mode returns to the real mode automatically when any switch is not pressed for more than 5 seconds.
※The range of the warning RPM which can be set is from 500rpm is to the maximum scale RPM.
※Set the lower RPM than the warning SET2 RPM.
If the warning SET1 RPM is set higher than the SET2 RPM:
→The warning SET2 RPM is changed to the same RPM as the SET1 RPM.
Ex) If the SET2
RPM
is set at 6000rpm, it is changed to 7000rpm when the SET1
RPM
is changed to 7000rpm.
To raise the set RPM of the warning, press ▲switch. Every time ▲switch is pressed, the set RPM is
raised in degree. If ▲switch is pressed long, the set RPM is raised faster. To lower the set RPM of the
warning, press ▼switch. Every time ▼switch is pressed, the set RPM is lowered in degree. If ▼switch is
pressed long, the set RPM is lowered faster.
The mode returns to the real mode automatically when any switch is not pressed for more than 5 seconds.
※The range of the warning RPM which can be set is from 500rpm is to the maximum scale RPM.
※Set the higher RPM than the warning SET1 RPM.
If the warning SET2 RPM is set lower than the SET1 RPM:
→The warning SET1 RPM is changed to the same RPM as the SET2 RPM.
Ex) If the SET1 RPM is set at 7000rpm, it is changed to 6000rpm when the SET2 RPM is changed to 6000rpm.
Set up the number of cylinders and buzzer. The factory setting of the number of cylinders is 4. If the gauge is installed in
a vehicle which the number of cylinders is not 4, change the number as follows. The factory setting of the buzzer is ON.
※Even if the battery is disconnected, the setting is not cleared.
The gauge performs the opening mode when the ignition key is turned on and performs the closing mode when the ignition
key is turned off.
※The brightness is at the maximum level during the opening mode regardless of the dimmer control setup.
※
In case any other Defi-Link products are already installed in the vehicle, supply power from the same source as the Defi-
Link products to perform the opening and closing mode at the same time. If the power is supplied from the different
source from the others, gauges may not perform the opening and closing mode at the same time.
①Opening and closing mode①Opening and closing mode
The gauge pointer points at the RPM in real time. The maximum RPM is recorded during this mode.
In the real mode, when the RPM exceeds the set warning RPMs, the warning LED and the indicator light up/blink as fol-
lows.

The following is the list of operations with switches. In the setup mode and the warning setup mode, the mode changes to
the real mode when any switch is not pressed for more than 5 seconds.
1.Function1.Function
1) Attach the buffer around the gauge.【Figure1】
※Do not touch on the front face of the gauge so as not to put fingerprints.
2) Fit the mounting rubber inside of the mounting band.【Figure2】
3) Fix the mounting band to the mounting bracket temporarily with the spacer, bolts,
washers, and spring lock washers. Tighten bolts loosely by hands. Do not use a
hexagonal wrench (Allen key) at this stage.【Figure3】
4) Insert the switch unit into the attachment for switch unit.【Figure1】
※If the switch unit is fixed to another place other than the gauge, do not use the at-
tachment for switch unit.
5) Fit the attachment for switch unit and indicator into the mounting band. And then fit
the gauge into the mounting band. Locate the switch unit and the indicator roughly
at this stage. The switch unit and the indicator can be positioned in the range which
they do not touch the mounting bracket and bolts.【Figure4】【Figure5】
※Do not take hands off from the gauge so as the gauge does not fall down.
※If the switch unit is fixed to another place other than the gauge, do not fix/use the
attachment for switch unit to the mounting band.
6) Identify the position of the mounting bracket with the gauge fitted into the mounting
band. Mark the shape of the mounting bracket and the position of the screw holes.
The figure printed on the package can be used to position the screw holes.
※To check that there is enough space for installation, identify the gauge position
with the gauge, switch unit, and indicator fitted into the mounting band.
※When setting the gauge angle, take care not to scratch by hitting the gauge to the
mounting bracket.
7) Disassemble the mounting band from the mounting bracket, and disassemble the
gauge, attachment for switch unit, and indicator from the mounting band.
8)
Attach double sided tapes on the bottom of the mounting bracket.【Figure1】【Figure6】
9) Fix the mounting bracket on the gauge installing position by using the tapping
screws.
10) Fit the attachment for switch unit, indicator, and gauge into the mounting band again.
Take notice that the angle of the switch unit and the indicator cannot be changed
while the bolts are fastened.
※If the switch unit is fixed to another place other than the gauge, do not fix/use the
attachment for switch unit to the mounting band.
11) Attach the double sided tape on the back side of the gauge.
【Figure1】【Figure6】
12) Pass the indicator wire and switch unit wire through the holes of the back case from
the outside. Connect the indicator wire to the connector on the gauge. Refer to part
names section.【Figure7】
13) Put the back case on the gauge. Position the hole for the power supply & tachome-
ter signal wire to the gauge connector for it. Refer to part names section. The indi-
cator wire can be stored in the back space in the back case.
14) Connect the switch unit wire to the connector on the back side of the gauge. The in-
dicator wire can be stored in the storage space in the back case neatly.【Figure8】
15) Connect the power supply & tachometer signal wire to the connector on the back
side of the gauge.【Figure8】
16) Fit the mounting band with the gauge in the mounting bracket by using a spacer,
bolts, washer, and spring lock washer.
※Depending on the installing space, it may difficult to fit the gauge. Do not pull
wires forcefully and take notice not to hit the vehicle by parts.
17) Fasten the bolts with a hexagonal wrench (Allen key) firmly.【Figure9】
18) Fit the regular position bezel onto the gauge with setting the ▼mark at the position
you like.
