When cleaning the computer, bracket and sensor, do not use thinners, benzene, or alcohol. •
A temperature sensor is built in the computer. If the sensor is heated by direct sunlight or •
body heat, it may not indicate the temperature correctly.
The altitude data with this unit is for reference only; accordingly, do not use this unit as a •
measuring device for professional use.
Dispose of used batteries according to local regulations.•
LCD screen may be distorted when viewed through polarized sunglass lenses.•
Wireless Sensor
In order to prevent any interference with the sensor signal, the transmission range is designed
to be 20 to 70 cm, in addition to use of the ID code. (This receiving range is only a reference.)
Please note the following points.
To use this unit, the sensor ID has to be set.•
Two different IDs, • ID1 and ID2, can be registered to this unit, which are identified automatically.
The computer cannot receive when the distance between the sensor and computer is too long. •
Temperature drop and battery drain may worsen the receiving sensitivity even if they are within
the transmission range.
Interference may occur, resulting in incorrect data, if the computer is:
Near a TV, PC, radio, motor, or in a car or train.•
Close to a railroad crossing, railway tracks, TV stations and/or radar base.•
Using with other wireless devices, or some particular battery lights.•
How to restart
After changing the battery, or when the computer displays an error, restart the computer according to the following procedure.
Press the 1. AC button on the back of the computer.

Resetting data
While displaying any data other than Dst-2, pressing and holding the MODE and SSE
simultaneously resets the measurement data to 0. While displaying Dst-2, pressing and
holding the MODE and SSE simultaneously resets only Dst-2 to 0. In both cases, the
total distance and total altitude gain are not reset.
Power-saving mode
If the computer has not received a signal for 10 minutes, power-saving mode will activate and
only the clock will be displayed. When the computer receives a sensor signal again, the measuring screen reappears. If 60 minutes’ inactivity elapses, power-saving mode will change to
SLEEP mode. Pressing the MODE in SLEEP mode brings up the measuring screen.
Altitude measurement
This unit detects the change in atmospheric pressure and temperature using a pressure sensor
built in the computer, and converts it to the altitude using the relation between the altitude and
pressure of ISO 2533 (Standard atmosphere), which was developed based on the international
standard atmosphere specified by the International Civil Aviation Organization (ICAO). Accordingly, the measurements tend to change, even at the same point, according to the atmospheric
pressure due to the weather condition. Furthermore, the measurements may change more
than 30 m from the early morning to the evening even under a stabilized weather condition.
The measurements may be incorrect in the following place or environment.
When the atmospheric pressure and temperature change significantly due to a rapid •
weather change.
In the place where the atmospheric pressure is regulated, such as inside an airplane.•
The altitude data may change temporarily when the temperature changes rapidly by get-•
ting out of a room, etc. It may return to a correct value after a while.
Altitude measurement
This unit has four altitude-related functions and temperature function.

Caution:
When Auto mode is Off, elapsed time counts even if the bicycle is not in motion.
After measurement, be sure to press MODE and SSE simultaneously to stop measuring.
It is updated when the measurement screen is displayed (while measuring: *
every 3 seconds, while not riding: every 20 seconds).
Sea level altitude correction
This unit determines the altitude by converting the change in atmospheric pressure and temperature; therefore, it may cause deviation from the actual sea level altitude. It is recommended
to correct the sea level altitude just before measurement, using either the following methods.
• ADJUST (sea level altitude correction): Enter the altitude at the current point.
Enter the actual value at the point where the sea level altitude is known,
such as along the seashore, or at a sign on the mountain, etc.
Press and hold * MODE and SSE simultaneously on the setting screen to reset the corrected value to the default (a value according to ISO2533).
• HOME (home altitude setting): Preset a specific sea level altitude.
Preset the sea level altitude at your home in advance. Move to the HOME screen,
and then return to the measuring screen by pressing MENU or the relevant shortcut. Then, the sea level altitude changes to the preset value. You can start with the
correct sea level altitude by setting home altitude before stating from your home.
The sea level altitude is corrected on the menu screen “Sea level altitude correction”. Move to the sea *
level altitude correction screen by pressing MENU or the relevant shortcut from the measuring screen.
Countdown distance
Once the target trip distance is set, the unit displays the countdown distance to the target,
and notifies at arrival. When the unit reaches the target distance, the countdown distance
appears and the value flashes. The screen returns to the original display in 5 seconds.
The target distance is set on the menu screen “Countdown distance setting”. Move to the countdown *
distance setting screen by pressing MENU, MODE, or the relevant shortcut from the measuring screen.
Changing the computer settings [Menu screen]
Pressing MENU on the measuring screen moves to the menu screen for setup change. Once inside the menu screen, press the MODE button to scroll through setup items. Press MODE+SSE to
enter the edit screens. Change cannot be done if there is an incoming signal and timer is active.

Troubleshooting
MODE 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.
The sensor signal reception icon does not flash (the speed is not displayed). (Move the computer near the sensor, and turn the front wheel. If the sensor signal reception icon flashes, this
trouble may be a matter of transmission distance due to battery drain, but not any malfunction.)
Set the sensor ID.
Set the ID according to “Sensor ID setting” on the menu screen.
Check that the clearance between the sensor and magnet is not too large. (Clearance: within 5 mm)
Check that the magnet passes through the sensor zone correctly.
Adjust the positions of the magnet and sensor.
Check that the distance between the computer and sensor is correct. (Distance: within 20 to 70 cm)
Install the sensor within the specified range.
Is the computer or sensor battery weak? In winter, battery performance diminishes.
Replace with new batteries. After replacement, follow the procedure “Replacing the battery”.
Incorrect data of the sea level altitude.
Is the sea level altitude corrected?
The sea level altitude may vary due to changes in atmospheric pressure. Correct the sea level altitude according to “Sea level altitude correction” on the menu screen.
No display.
Is battery in the computer run down?
Replace it. Then restart the computer referring to “How to restart”.
