Start or Stop of Measurements.
The computer can be programmed to run in either MANUAL MODE or
AUTO TIME MODE. In Manual Mode you must press the START / STOP
button to turn on and off the Timer, which records Distance and Average
Speeds. In Auto Time
the computer turns the Timer on and off de-
pending on a signal from the sensor.
When speed is detected by the computer and the Timer is running, the
km/h or mph will flash. Speed will appear on the computer screen and
the Odometer will record, regardless if the Timer is running or not.
• Auto Time Mode (Automatic Measurement)
In AUTO TIME mode, the letters
will appear on the computer screen.
Elapsed time, Average and Distance are recorded automatically and the
Timer, stops when the speed stops. In this mode the START/STOP button
is not operable.
• Manual Measurements
When you don’t see the icon
on the screen, you can start or stop the
measurements by pushing the START/STOP button.
When you push the button, measurements of Elapsed Time, Average
Speed, Trip Distance 1 and 2 are started and they are stopped with the
second push of the button.
• How to set ON or OFF the auto-mode
Push the SET button on the back side of the computer while Elapsed
Time, Average Speed, Trip Distance 1 or 2 is displayed, then the icon
is lit” (ON) or turned OFF.
Resetting Elapsed Time, Trip Distance, Average Speed and Max Speed.
Press and hold the MODE and START/STOP buttons for 2 sec. in either
the Elapsed Time, Trip Distance 1, Average Speed or Maximum Speed
functions to reset these functions. The Odometer and Trip Distance 2 are
not reset. See below for details.
• Resetting Trip Distance 2
Trip Distance 2 is reset independently. When Trip Distance 2 is on the
screen, press and hold both the MODE and START/STOP buttons to re-
set.
Computer Functions
• Power-saving Function
When no signal has been received for about one hour, the computer goes into the power savings
mode to only display the Clock. When any button is pushed or the wheel is rotated, the computer
screen reappears.
• Dual Tire Size
You can program two,
and , tire circumferences and can easily switch to or vise
versa to enable the system to be used by two bicycles which have different tire sizes. The com-
puter program for circumference
is programmed for low speed use. We recommend to use
this for MTB's.
• Moving Elapsed Time, Average Speed and Maximum
Speed to the upper display.
You can move the Elapsed Time, Average and Max Speed
displays to the upper display for easier viewing. Hold the
START/STOP button for 2 sec. and the sub-display will ap-
pear in the upper display. Hold the START/STOP button
again for 2 sec. and the display returns to the normal set up.
Troubleshooting
No display appears.
Is the battery dead?
Replace it by the new one and do all clear procedure.
Strange data appears
Do all clear procedure (write down the number of Odometer if possible before doing the all
clear procedure and input it manually after choosing the measurement unit).
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 opera-
tion of the button.
No speed data is displayed.
(If the speed data is not displayed, have the contact points short-circuited 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 sensor may 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.
Make sure that the contact points of the bracket or of the main body are free from dirt.
Wipe the contact points clean.
Is the cord not broken? Even if the outside of the cord looks normal, a breakage in the wire can occur.
Replace the bracket and sensor set with a new one.
Maintenance
• To clean the computer or the attached parts, use diluted neutral detergent
on a soft cloth, and wipe it off with a dry cloth.
Replacing The Battery
When the display gets dim, replace the battery. If you want to retain and
use the current reading of odometer, write down the odometer data before
replacing the battery.
• Put a lithium battery CR2032 in the computer with the (+) mark facing up.
• After replacing the battery, do the necessary set-up of the computer in
accordance with "Computer Set-up".
