Maximum angle of deflective 270°(full sweep) is controlled by the microcomputer up to 4600 division（0.057°each) to provide high precision in the accuracy of information generated.
The stepping motor is sufficient for quick response of all sorts of professional motorsports.
●LED illumination
The gauge dial is invisible while the ignition switch is off. Once the ignition switch is turned on, a clear
display appears by colored LED illumination.
The gauge dial illumination and the red emitting needle pointer provide high visibility.
●Opening and closing modes
The gauge dial and the needle pointer performs opening and closing modes interlocked with turning
ON/OFF of the ignition.
●Adjustable brightness
There are 5 stages of brightness for the daytime and 6 stages for the nighttime. The brightness can be
decreased/increased with the vehicle lights switched on/off.
●Dual warnings of light and buzzer
Two customer-defined warning RPMs can be set. When the RPMs are exceeded, the warning LED
blinks/lights up and the warning buzzer sounds.
●Exclusive large-sized indicator
The exclusive large-sized indicator which lights in green and red enhances the visibility of warnings inaddition to the warning LED in the gauge.
●Peak memory function
The maximum RPM during driving can be stored and checked later.
●Detachable switch unit
The large-sized switch unit with light is fixable on the gauge and is also detachable.
●Exclusive mounting band and back case
The gauge is clinched by using the exclusive mounting band and back case. Wires can be stored in
the back case neatly.
●Integrated rev adapter
By having the Defi rev adapter built-in, the tachometer works on vehicles with DIS (Distributor-lessIgnition System) which engine speed signals cannot be picked up due to connection vehicle control
units with serial communication.

φ86.8(3.42")●Ensure that the vehicle will remain stationary and turn off the engine before installing this product. Failure to do so
could result in a fire, and could make the vehicle move during installation.
●Remove the key from the ignition and disconnect the negative (-) battery terminal prior to installation of this product.
Failure to do so could result in a fire caused by an electrical short circuit.
●Take care not to install this product in a way that interferes with safety equipment such as seat belts and air bag
systems or vehicle operation equipment such as engine controls, steering wheel or brake systems. Interferencewith normal operation of the vehicle can result in an accident or fire.
●Solder or use a solderless connector for wiring connections and make sure connections are insulated. In areas
where there could be tension or sudden impacts on the wiring, safeguard the wiring with corrugated tubing or othershock absorbent material. Accidental shorts can cause fires.
●The ignition-switched +12V(IGN) line must be connected to the vehicle's ignition-switched wire with a fuse of 30A or
less. High-capacity fuse(more than 30A) will not blowout even with an abnormal current flow and may cause fire.
●Use a fuse of regulated capacity when the fuse of the power wire is changed. Using a fuse that exceeds regulated
capacity may cause fire.

2. Switch operation list
The following is the list of operations with switches. In the setup mode and the warning setup mode, the mode changes tothe real mode when any switch is not pressed for more than 5 seconds.

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】

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 attachment 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 theattachment for switch unit to the mounting band.

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.

→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.

In the real mode, the mode changes to the warning setup mode SET2 if ▲switch is pressed for morethan 2 seconds. In the warning setup mode SET2, the warning LED blinks as follows:

Set up the numberof cylinders and the buzzer on/off in the setup mode. The mode returns to the real mode automaticallywhen any switch is not pressed for more than 5 seconds.

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 themounting bracket.
7) Disassemble the mounting band from the mounting bracket, and disassemble thegauge, attachment for switch unit, and indicator from the mounting band.

STEP４ Final check and setup
1) Make sure the gauge is fixed on the installing position firmly. Then turn the vehicle engine on and off and check the
movement of the pointer, illumination of the gauge, and engine speed signal input.
※Make sure there are no tools on the vehicle floor and that the vehicle surrounding is safe before turning on the engine.
2) Go on to the operation section and set up the number of cylinders, and so on. Give this manual to the customer if
he/she sets up by himself/herself.

※In case any other Defi-Link products are already installed in the vehicle, supply power from the same source as the DefiLink 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.

②Real mode
The gauge pointer points at the RPM in real time. The maximum RPM is recorded during this mode.

If the buzzer is set on, it feeps (a long beep) when the RPM exceeds the warning SET2 in the realmode. If the buzzer is set off, it does not sound.

In the real mode, when the RPM exceeds the set warning RPMs, the warning LED and the indicator light up/blink as follows.

※The buzzer sounds when switches are pressed. It cannot be turned off.

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】Time

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 notsound.

The mode returns to the real mode automatically when any switch is not pressed for more than 5 seconds.

3. Setup【Figure6】How to use double sided tape

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.

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 thepeak mode returns to the real mode.
※Even if the battery is disconnected, the recoded maximum RPM is not cleared.
