Measure wheel circumference (L) of your bike
To get the most accurate calibration, do a wheel roll-out. With the valve stem perpendicular to the ground, mark the pavement at the valve stem. With the rider's weight on the bike, roll the wheel one tire revolution in a straight line and mark the ground when the valve stem is perpendicular to the ground again. Measure the distance in millimeters. This is the most accurate wheel calibration number.

Attach the bracket to the stem or handlebar
When attaching the bracket to the stem:
Place bracket (2) on the stem. Secure with bracket band (1) and nut (3). Caution: Tighten the bracket, ensuring that the cable does not get caught in the stem. Cut Caution: Round off the cut edge of the bracket band to prevent injury.
When attaching the bracket to the handlebar:
Place bracket (2) on the handlebar. Secure with bracket band (1) and nut (3). Caution: Tighten the bracket, ensuring that the cable does not get caught in the handlebar. For wing type handlebar or oversized stem, bracket can be mounted using the Bracket Holder and nylon ties (Option).
-
Wrap the cable around the front brake cable
Route the sensor cable along the front brake cable. Caution: Turn the handlebar to make sure wire does not hinder full rotation.
-
Install the sensor and magnet
Install the sensor: Attach sensor (4) to the inside of the right front fork using sensor rubber band (6) or nylon ties (10). Ensure the sensor line is positioned correctly. Caution: Attach between one and three sensor pads (8), putting them together as required.
Install the magnet: Attach magnet (5) to a spoke on the right front wheel. Ensure the magnet passes through the sensor line (A). The clearance between the sensor surface and the magnet must not exceed 5 mm (B).
Pull securely.
-
Remove/install the computer
While supporting it by hand, push the computer (not pictured) out as if lifting the front up to remove. To install, slide it onto the bracket until it clicks.
* After installation, rotate the front wheel gently to check that the speed is displayed on the computer. If the speed is not displayed, check that conditions A and B are satisfied.

*1 With the computer installed on the bracket, press on the three raised dots on the face of the computer.
*2 If Tm exceeds approximately 27 hours or Dst exceeds 999.99 km, .E (Error) is displayed as the average speed. Reset data.
Switching Computer Function
Pressing [MODE button] switches function, in order, as shown on the left.
Resetting Data
To reset measurement data, display any data other than for Dst-2 and then press and hold [MODE button]. Pressing and holding [MODE button] with Dst-2 displayed resets Dst-2 only. The total distance is never reset.
Power-saving Function
If the computer has not received any signal for an hour, power-saving mode will activate and only the clock will be displayed. Alternatively, if the sensor detects a signal or [MODE button] is pressed, the main display reappears.
Changing the Computer Settings [Menu Screen]
To bring up the menu screen, press [MENU button] in any mode. Each time [MODE button] is pressed, the relevant menu screen appears. Pressing and holding [MODE button] changes the setting of the displayed menu.
- Wheel selection: Toggle between the specified wheel size (tire circumference) A and B. Use this function if the computer is to be shared between two bicycles. Pressing [MODE button] toggles between A and B.
- Wheel size entry: Pressing [MODE button] increases the value, and pressing and holding [MODE button] moves to the next digit. * To enter the wheel size, display using "Wheel selection".
- Clock setting: To set the clock, refer to "Preparing the computer - 4".
- Total distance manual entry: Before reinitializing the computer, note the total distance. This reading will later allow you to enter the total distance manually. Pressing [MODE button] increases the value, and pressing and holding [MODE button] moves to the next digit.
- Speed unit: Pressing [MODE button] toggles between km/h and mph.
* After changing, be sure to press [MENU button] to register the setting.
* If the menu screen is not touched for a minute, the Measuring screen reappears without data changes.
Maintenance
To clean the computer or accessories, use diluted neutral detergent on a soft cloth, and wipe it off with a dry cloth.
Replacing the Battery
If the display appears faded, replace the battery. Install a new lithium battery (CR1620) with the (+) side facing upward. Then reinitialize the computer referring to "Preparing the computer".

Battery: CR1620
Troubleshooting
- MODE button does not work when the computer is mounted on its bracket. Check that there is no dirt between the bracket and the computer. Wash off the bracket with water to get rid of any dirt, and to ensure that the computer slides in and out smoothly.
- Speed and distance are not displayed. (Touch a metal item against two contact points of the computer several times to create a short circuit while observing the display. If a numeric value appears, this signifies that the computer is functioning normally.) Is the clearance between the sensor and magnet too great? (must be ≤ 5 mm) Does the magnet pass through the sensor line? Adjust the positions of the magnet and sensor. Is there any foreign matter (which would prevent a clean contact) on the contact points of the computer and/or bracket? Clean the contact points. Check that no wire cable is worn or broken. Even with a normal appearance, it may be that a wire cable could be broken internally. Replace the bracket sensor set.
- No display. Is battery in the computer run down? Replace it. Then reinitialize the computer referring to "Preparing the computer".
- Incorrect data appear. Reinitialize the computer referring to "Preparing the computer".
