Be sure to make preparatory settings. The unit will not operate properly without the settings being made.

Set up while the vehicle is stationary.

Confirmation

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

alternately. 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
seconds.

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
seconds.

※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

follows.

②Real mode②Real mode

③Warning mode③Warning mode

In the real mode, the peak LED lights up and the mode changes to the peak mode by pressing ▲switch.
The recorded maximum(peak) RPM is displayed during the peak mode. Every time the maximum RPM

is updated, it is recorded. The peak mode returns to the real mode by pressing ▲switch again.
In the peak mode, the peak LED blinks and the maximum RPM is reset by pressing ▲switch. Then the
peak mode returns to the real mode.

  ※Even if the battery is disconnected, the recoded maximum RPM is not cleared.

In the real mode, the brightness of the gauge illumination is controlled by pressing ▼switch. There are
5 stages for the daytime and 6 stages for the nighttime. The brightness can be decreased/increased
with the vehicle lights switched on/off.

 ※Even if the battery is disconnected, the set level is not cleared.

※The brightness level does not change even if ▲switch is pressed. The mode changes to the peak mode.

Condition Possible Cause Corrective Action

○Wiring of the power supply wire is

improper.

○The locks of the solderless connectors

are not locked tightly.

○Does not operate.
○Power is not supplied.

○Check wirings of +B, IGN, GND as per

instructions in this manual.

○Check the lock of the solderless connectors.

○Wiring of the tachometer signal is wrong.
○Setting of the number of cylinders is

wrong.

○The RPM is not displayed

correctly.

○Check wiring as per instructions in this manual.
○Check the number of cylinders as per instructions

in this manual.

○Originally equipped gauges commonly

indicate up to 10% higher RPM.

○The RPM gauge indicates is

a little lower than that of

originally equipped gauge.

○Check if the difference is up to 10%. This

product is designed emphasizing accuracy and
should have little error margin. If the difference
is bigger than 10%, check the setup of the
number of cylinders.

○The battery wiring is wrong.
○The fuse of the power supply wire is

blown out.

○Does not carry out the

closing mode.

○Check wiring of +B as per instructions in this

manual.

○Make sure the wiring is not touched on the

vehicle body and then change the fuse.

○Check the solderless connector of battery wiring.

○The warning set1 RPM is set higher than

the warning set2 RPM or the warning
set2 RPM is set lower than the warning
set1 RPM.

○The warning LED lights up

at the different RPMs than
set RPMs.

○When the warning set1 RPM is set at the higher

RPM than the warning set2 RPM or when the
warning set2 RPM is set at the lower RPM than
the warning set1 RPM, set RPMs are changed

automatically. Refer to Operation section.

○

The illumination is in the brightest level of

nighttime mode.

○Wiring of the power supply wire is

improper.

○The illumination brightness

doesn't change by turning
on/off the vehicle
illumination.

○Check if the illumination is in the brightest level of

nighttime mode and press ▼switch.

○Check wiring of ILM as per instructions in this

manual.

○Check the lock of the solderless connectors.

○The pointer moves during transfer.○The needle pointer is not

downward before the
electricity is turned on.

○It is an inherent property of the stepping motor.

The pointer may move when a slight impact is
made to the gauge. Check if it operates normally
by turning on and off the electricity and the pointer
points zero after the ignition is turned off.
