No display appears.
Is the battery dead?
Replace it and do all clear procedure.
Strange data appears.
Do all clear procedure.
Note: Data of odometer is also erased.
Measurements do not start when the START/STOP button is pushed.
Is the icon ON?
Turn the Auto-Mode off to enable the start or stop of the measurements by manual operation of the button.
No speed or cadence data can be measured.
(If the speed or cadence data is not displayed, have the contact points short-circuited a few times by a metal plate. In the case that this short-circuiting is detected by the computer, the computer
is considered normal and the bracket and the sensor possibly have the cause of trouble.)
Is the gap between the sensor and the magnet too big? (should be within 5 mm)
Does the marked line of the sensor align with the center of the magnet?
Adjust the position of the magnet and the sensor.
Wipe the contact points of the bracket or computer clean.
Is the cord broken? Even if the outside of the cord looks normal, there could be damage.
Replace the bracket and sensor set with a new one.
The contacts to be short-circuited intermittently are located on the back.
AT100
Note: When the current speed does not appear, short-circuit the two contacts on the back with metal a few times. If the speed display returns, the main unit is in normal condition.
Display response is slow.
Is it the temperature under 0?C (32?F)?
It returns to normal when the temperature rises. It does not affect the data.
No display appears. Or the display disappears when the light button is pressed.
Has the battery worn out? Or is it about to wear out?
Replace it with a new one (CR2032). (*After replacing the battery, be sure to press the AC button and to reset the speed scale, temperature scale and the clock time again.)
Incorrect data appears.
The static electricity may cause an incorrect display.
Press the AC button and reset the speed scale and the clock time again.
Current speed does not appear.
Is there anything on the contact of the main unit or the bracket?
Wipe the contact clean.
Is the distance between the sensor and the bracket too far?
Are the magnet's center and the sensor's marking line aligning?
Adjust the position of the magnet and the sensor correctly.
Is the wire broken?
Replace the bracket & sensor part with a new one.
Transmission signal loss in damp or wet conditions.
Water or condensation may collect between the bracket sensor and the computer causing an interruption in the data transmission.
Wipe the contacts with dry cloth. Contacts can also be treated with a water repellent silicon jell from an automotive parts or hardware store. Do not use industrial water repellent; it may damage the bracket.
The S/S button does not start/stop measuring.
Is the unit in the Auto function?
In the Auto function, this button doesn't work.
When using the unit apart from bicycle, it doesn't measure altitude.
Is the bicycle symbol on (i.e. is it on the cycling mode)?
Clear off the bicycle symbol, and turn to the continuous measuring mode.
The unit does not measure altitude.
Is there anything clogged in the altitude sensor cover?
Clean it off according to "Daily Care". (If the cleaning still doesn't work, press the AC button; and reset the speed scale, temperature scale and the clock time.)
The current altitude shows incorrect data.
Is the correction of the current altitude appropriately done?
The current altitude is influenced by the change of the pressure.Make corrections in each ride.

No display.
The battery in the computer run down?
Replace it with a new one and do all clear operation.
Incorrect data appears.

Cannot start measuring by START/STOP button.
Is the AT icon on?
To operate manually, switch off the Auto Time.
Sensor pulse indicator does not flash.
(Current speed does not appear.)
[If the sensor pulse indicator fails to flash, first spin front wheel to align computer with sensor. Indicator will flash if computer is working. If not, this will pinpoint the problem to be: 1. dead battery; 2. distance between sensor and unit is over 70cm.]
Is the clearance between the sensor and the magnet too large?
Are the magnet's center and the sensor's marking line aligned?
Re-adjust the positions of the magnet and the sensor.
Is the distance between the computer and the sensor too long?
Adjust the sensor's position so that the distance becomes less than 70cm.
The battery in the sensor run down?
Replace it with a new one. *In winter, battery's performance is degraded.

The size of the figures on the screen is reduced.
When the bigger font size is selected (100%, 70%, 50%), and if the number of digits for trip distance and total distance exceed the maximum number of digits, the size is automatically reduced to fit on the screen.
The last ride day data is not correct.
Is the clock time setting correct?
The last ride day data is saved when the clock time passes the midnight. Therefore, if your clock is not correctly set, the data shown will be incorrect.
Is the unit measuring?
The last ride day data is not updated unless it measures new data. (See page 10.)

Are the magnet's center and the sensor's marking line aligned?
Re-adjust the positions of the magnet and the sensor. (The clearance should be less than 5mm.)
