INSTALLING HYPER-BRAIN
Speed
Sensor
(Fig.A)
<For HyperMag & HyperRim>
Peel off the silver sticker cover on the Flywheel Cover.
1
Install the Speed Sensor into the hole and tighten it with the supplied Knob Bolt. (see Fig.A)
Knob Bolt
If your HyperMag or HyperRim trainer is the remote control model (Type-R) and
2
was made prior to 2000, you can set-up the HyperBrain together with the Remote
Shifter via the Support Stay. (see Fig. B)
The Support Stay will be attached with the supplied M4 Bolt (larger one).
(see Fig. C)
If your model is the dial control one (Type-D) or later than 2001 model, use the
supplied plastic Handlebar Mount instead of the Support Stay. (see Fig. D)
To use the Support Stay, slide the Plate Nut into the slit on the backside
3
of the Base, put the stay on it and tighten with the supplied M3 Bolt
(smaller one). (see Fig. C)
At this time, make sure the projection on the stay is on the Release
Lever side.
Then slide the Main Unit into the Base until it clicks into place.
To use the plastic Handlebar Mount, remove the bolt and the
4
vinyl cap then coil the band around your handlebar or somewhere with the same diameter. This band will fit a 22.2mm
diameter.
Put the supplied rubber pad between the band and the handlebar if you need.
Tighten the bolt firmly and simply slide the Main Unit into the
Base until click.
In this case, you don’t need to use the Plate Nut.

(Fig.D)
To avoid damaging the signal wire with the spinning crank, we recommend you to wrap both the
!
remote shifter cable and the signal wire with the supplied Spiral Tubes as shown in Fig.E.
When the HyperBrain is not in use, we recommend you should plug the hole on the Flywheel Cover
!
with a seal or a vinyl tape to prevent a noise caused by the spinning flywheel.

<For RDA InterRim Ergo>
If your RDA InterRim Ergo is later than 2001 model and has a hole on the Roller Support
Stay, you can install HyperBrain on it. PLEASE NOTE: There is no hole on this model
before 2000. Please look over and read the “Installing HyperBrain” section on the previous
page first to know how you should do it.
Put the RDA Bracket on the backside of the Roller Support Stay, and tighten with the
1
supplied M4 Bolt (larger one). (see Fig. F)

Install the Speed Sensor on the RDA Bracket. (see Fig. G)
2
Install the Magnet Sensor on a spoke of your rear wheel (usually you should choose
3
the opposite spoke to the air valve for better balance). Be sure you set it at same height
as the Speed Sensor. (see Fig. H)
T o install the sensor , remove the Nut from the Magnet Sensor and sandwitch the spoke
with both parts, then tighten it firmly . Put the spoke into the cut out section on the Nut.
Face the magnet to the Speed Sensor side.
Set the Speed Sensor position so the clearance between the Speed Sensor and the
4
Magnet Sensor is around 2 or 3 mm. (see Fig. I)
To avoid the problem of th sensor and magent hitting together, keep
!
the clearance as suggested above.
If the clearance is too wide the sensor will not work.

(Fig. I)
Start/Stop Button (right button)
Measuring of the Trip Distance and Elapsed Time is simultaneously started or stopped when the Start/Stop button is pressed.
During operation the speed scale symbol flickers.
Set Button (middle button)
When this button is pressed in the stop state in each mode, the following value can be changed;
• In (O) mode: Wheel Circumference
• In 24-hour Clock mode: 24-hour Clock
• In (T),(D) or (A) mode: on/off the Automatic Start/Stop
RESET
Select any mode except Total Distance (O), and press the Mode button and Start/Stop button simultaneously. The memorized Trip Distance, Elapsed Time, Average Speed and Maximum Speed will be erased. (When the two buttons are pressed in
“O” mode, the wheel circumference stored will be displayed.)
ALL CLEAR
When the AC button on the backside of the computer is pressed, all data stored in memory (trip distance, speed scale, wheel
circumference and clock time) will be erased. All displays illuminates, then the “mile/h” symbol alone appears. This operation should be executed only when irregular display occurs or no display appears. Since all the memories are erased, set the
main unit again according to "Main Unit Preparation".
