Cateye Mity 8 CC-MT400 - Cyclocomputer Manual

Installation of the Computer on Your Bike

The computer is combined with the following parts.

1. Bracket
2. Cord
3. Sensor
4. Sensor Rubber Pad
5. Magnet
6. Bracket Rubber Pad
7. Nylon Ties (5)

1. Mount the magnet
   on a spoke of the front wheel so that the surface of the magnet will face the sensor.
   
2. Mount sensor and adjust the gap between the magnet and the sensor.
   Secure the sensor with the larger nylon ties at the appropriate place and in the right direction.
   

Mount the sensor at the appropriate position so that the center of the magnet will align with the marked line on the sensor when the wheel is rotated.

Rotate the sensor on the front fork to adjust the gap between the sensor and the magnet within 5 mm, and secure it with the nylon ties.

3. Mount The Bracket
   Secure the cord on the front fork with the nylon ties (smaller ones) and coil it around the brake cable that leads to the handle bar. Put the rubber pad on the bracket and secure the bracket on the handle bar with the screw. Slide the computer into the bracket until you hear the click sound The contact points are automatically closed. When you need to remove the computer, slide forward the computer with the lever pushed simultaneously.
   Note Allow enough wire clearance in the area marked with an to insure that you can turn the handlebar from left to right without pulling the wire.
   
   
4. Basic Functions Test
   Rotate the front wheel gently and see if the computer indicates the running speed.
   
   Note When the computer does not indicate the speed, check the position of the magnet and the sensor.

• Pay attention to the road or trail! Do not be distracted by the computer.
• Be sure to securely mount the magnet, the sensor, and the bracket on your bicycle. Periodically check to insure they are mounted securely and the screws are not loosen.
• Keep batteries out of reach of small children. Dispose of batteries according to local regulations.

• Avoid unnecessary prolonged exposure to the sun. Never attempt to disassemble the computer head.
• Don't use thinner, benzene or alcohol to wipe the surface of the computer. They may damage the surface of computer.

Computer Set-up

For 1st use or after replacing the battery

1. All Clear
   Push three buttons (MODE, START/ STOP and SET) at the same time.
   * Do this procedure without fail for stable measurement when you use this system for the first time and every time the battery is replaced.
   
   
2. Select The Measurement Unit
   Select the measurement unit, kilometer or mile, by pushing the MODE button.
   
   Choose Either of The Followings.

• When you want to input the reading of the currently used odometer, keep pressing the MODE button for two seconds and input the reading.
• When you want to start the odometer from zero, push the START/STOP button.

Starting the odometer from zero.

Retaining the current odometer reading
(the odometer starts from the reading you inputted)

Input the current reading of odometer.

3. Set The Tire Circumference
   Set the tire circumference in cm.
   Note You can easily set it by referring to the chart shown right.
   Setting is completed by pushing the SET button.
   

   You need to know the tire circumference (L cm) beforehand.
   

Preparation Complete.
(the screen will show the time measurement in this state)

* The auto mode is ON in this state.

You can refer to the guide chart to roughly know the tire circumference.

Tire size is usually shown on the sidewall of tires.

Computer Operations

Selection of the data-display mode

Pressing the MODE button changes the functions in the sub-display.
Clock Time - In Elapsed Time, press and hold the Mode button for two seconds to display Clock Time. Pressing the Mode button again will return the sub-display to Elapsed Time.
Trip Distance 1 and 2 – The computer has two separate trip distances. Trip Distance 2 is reset independently. It can be used to record distance within a ride or multiple days distances. In Trip Distance 1, press and hold the Mode button to select Distance 2. You will continue to view this distance until you select Distance 1 with the same procedure.

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 depending 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 reset.

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 computer program for circumference is programmed for low speed use. We recommend to use this for MTB's.

How to select tire size or

When data other than Odo is displayed
Keep on pressing the button for two seconds

When the Odo data is displayed

Keep on pressing buttons for 2 sec. at the same time

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 appear 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 operation 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".
