Parts Installation

* If you already have CAT EYE Cyclocomputer (Model CCMT300, ED200, ST300 and AT100), you can use the same bracket and sensor; so you do not need parts installation. Just attach the 2Dx attachment on your bracket.

Magnet
Use a coin to attach the magnet 2 temporarily to the right side spoke of front wheel.

Speed Sensor

Attach the speed sensor temporarily to the right front fork. Adjust the sensor 2 and the magnet 0 referring to the above A and B. After adjusting, tighten the screw 9 and the magnet 0. Reference: If the clearance between spoke and front fork is wider than 5mm, mount the sensor band 3 and 4 in an opposite way as shown.

front fork

Secure the wire along the fork using the nylon ties 5 and wind it round the brake cable up to the handlebar. Caution: Allow enough wire clearance in the area marked with.

Bracket

Attach the bracket rubber pad with holder 8 to the bracket 1 and mount it to the handle bar. Reference: If it does not fit well, use the rubber pad 7.
2 Chestbelt Heart Rate Sensor
Attaching Main Unit and Chest Belt Before Wearing Chestbelt Heart Rate Sensor
WARNING!! Pacemaker users should not use this unit. Caution: Attach the Chestbelt Heart Rate Sensor at the center of your chest. The electrode belts must be contacting your skin. When wearing the chest belt heart rate sensor, ensure that the top mark on the transmitter comes to the top. If worn upside down, signals transmittable distance might become shorter. For the best results, it is recommended to moisten the electrode areas, or smear electrolytic cream, which is used for electrocardiograph. If skin irritation occurs, the Chestbelt Heart Rate Sensor can be worn over lightweight underwear; in this case, always moisten the electrode areas. Chest hair may prevent correct measurement.
How to wear Chestbelt Heart Rate Sensor
1. Adjust the length of the chestbelt to your chest size. Caution: Wear the chestbelt in comfortable way. If the chestbelt is too tight, you will feel pain during exercise. 2. Hook attachment belt to electrode belt at the front of your chest. Be sure to attach electrode area of the chestbelt to your skin closely.
1 Attachment Belt 2 Electrode Belt 3 Transmitter
MSC Wireless Heart Rate Sensor
Reference: If you wear the chestbelt indirectly on the skin, moisten the electrode area for the best results. Dry skin will cause measurement error in winter, even if the chestbelt is attached to your skin directly.

Top mark

3. Adjust the chestbelt so that the transmitter is placed at the front of your chest (under breast). Wear the chest belt heart rate sensor in the legible way (the top mark on the transmitter should come to the top).

MainUnit

Setting up Main Unit

(1) Initial Setting

!-1 Select a Speed Scale

wheel circumference
The main unit has 6 buttons: SET/AT button, MODE button, LAP button, LT button, S/S button and AC button. (! -1) Follow the instruction below for the initial setting. 1. Push AC button. Then the entire screen illuminates and gives a beep sound. Speed scale km/h flashes. Push the MODE button to switch between km/h and mph. (! -2)
2. Push SET/AT button to choose the desired speed scale. Then the wheel symbol appears and the initial figure 2096 flashes. (! -3)
Setting the Wheel Circumference
3. Input your bicycles wheel circumference obtained from the above table. Push MODE button to increase the digits, and LAP button to decrease. (To increase/decrease rapidly, hold down the respective button.) Caution: This is just the temporary setting of the wheel circumfer!-3
ence. For more accurate measurement, input the exact wheel circumference. When you want to change wheel circumference later, refer to Changing wheel circumference in page 13 of the user manual. 4. Push SET/AT button to fix the setting, and the screen shows Current Speed in the upper display, Heart Rate in the middle display and Elapsed Time TM in the lower display (! -4). Initial setting is completed.

Elapsed Time TM

(2) Basic Operations
Start and stop measurement Push S/S button and the unit will start measuring Elapsed Time TM. At the same time, calculation of Trip Distance DST and Average Speed AVS starts. The symbol of bpm in the middle display flashes while measuring. Push S/S button again and the unit stops measuring and calculation. "Current Speed measured and displayed regardless of the start/stop. Switching Functions The upper display always shows "Current Speed ", and the middle display always shows "Heart Rate ". ", "Heart Rate ", Total Distance ODO, Maximum Heart Rate MXP and Maximum Speed MXS continue to be

In the lower display, the selected function is displayed. Push MODE Button to switch functions of the lower display. The functions of the lower display are divided into the Main functions and Sub functions. Each Main function has its corresponding Sub function. To go back to Main function, push MODE button.

(3) Setting Clock Time
If you chose km/h for speed scale, clock time is in 24h mode; if you chose mph, clock is in 12h mode.
1. Before entering into the clock setting mode, see that the bpm symbol in the middle display is not flashing. If bpm is flashing, push S/S button to stop it. 2. Push Mode button to scan the lower display to show the icon. (#-1)

(#-3) 4. Push SET/AT button and clock setting is completed.

(4) Checking Sensors

Shows Current Speed
Spin the front wheel and see if the speed appears in the display. If the speed stays zero, the position of the speed sensor and the magnet is not correct. Re-adjust the position so that it meets the conditions A and B in Bracket/Sensor installation

Shows Heart Rate

Heart Rate Sensor
1. Wear the chestbelt sensor. 2. Stand by your bicycle. If the heart icon does not flash, re-adjust the location
of the Heart Rate Sensor according to the previous instructions.
After checking the sensors, take a test ride and see how the unit works.

Other Important Features

The following features and operations are important when you use MSC-2Dx.

Auto time feature

When this function is on, icon appears. The main unit detects the wheel rotation and automatically starts/stops measurement. In the default state, this function is off. To switch on/off this function, push SET/AT button when the lower display is either Elapsed Time TM, Average Speed AVS or Trip Distance DST. Caution: When this feature is on, you cannot start/stop the measurement by button operation. Therefore this feature is useful only when riding bicycle. When you use this unit on your wrist as a heart rate monitor, turn off the Auto time feature.

Changing Upper Display

In the Default State the upper display always shows "Current Speed ". However, you can change it to Clock, by pressing SET/AT button and S/S button simultaneously (in this case "Current speed " comes down to the lower display and joins in the main function). *When Auto function is on, just push S/S button and the upper display changes from " to "Clock time ". "Current speed

Reset Operation

To reset the data of Elapsed Time TM, Average Speed AVS, Maximum Speed MXS, Maximum Heart Rate MXP and Trip Distance DST, push S/S button and MODE button simultaneously.

Pace Arrow

When you are using the unit for cycling, the pace arrow appears in the right side of the lower display. The pace arrow indicates whether the current speed is higher or lower than the average speed. When the average speed is zero, no arrow appears.

Power Saving Feature

When the main unit is left without receiving any signal or there is no button operation for about 15 minutes, power is shut down and the unit will be in sleep state, displaying only clock. By receiving signal from the wheel, or by a press of any button other than LT button, the screen returns to normal.

LT button

When you push this button, the screen will illuminate for 3 seconds. MSC-2Dx provides you various functions such as Record memory feature and Heart rate target zone. For more detail of these functions, read the user manual.
