* If you already have CAT EYE Cyclocomputer Model CC-

CD100, you can use the same bracket and sensor; so you
do not need parts installation. Just attach the 3Dx

Attaching Chest Belt and Main Unit

Chestbelt Heart Rate Sensor

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.

How to wear Chestbelt Heart Rate Sensor

When wearing the chest belt heart rate sensor, ensure that the top mark on the transmitter comes to the top. If
worn upside down, signal’s 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.

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.

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.

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).

(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 ", "Heart Rate ",
“Cadence ”, “Total Distance ODO“, “Maximum Heart Rate MXP“ and “Maximum

Switching Functions

The upper display always shows “Current Speed ”, and the middle display always shows “Heart Rate ”. In
the lower display, the selected function is displayed. Push MODE button to switch functions of the lower display.
As illustrated below, the lower display changes as TM (Elapsed Time) –> Cadence C –> Clock –> AVS (Average
Speed) –> Dst (Trip Distance). These five functions are called “Main functions”, and each Main function has its
corresponding Sub function. (Cadence does not have Sub function.) To switch from one Main function to its sub
function, hold down MODE button. To go back to Main function, push MODE button. You can not switch the Sub
function to one another.

(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. Push SET/AT button and the hour flashes. Increase them by pushing MODE but­ton (to increase rapidly, hold down the button.) (#-2)

Push S/S button and the minute flashes. Increase them by the same way as in 3.
(#-3)

4. Push SET/AT button and clock setting is completed.

(4) Checking Sensors

Speed Sensor

Spin the front wheel and see if the speed appears in the display.

Cadence Sensor

Press MODE button and navigate to Cadence in the lower display. Spin the crank
reversely and check if Cadence starts counting.

If the speed and the cadence stays zero, the position of the sensor and the
magnet is not correct. Re-adjust the position so that it meets the conditions A
and B in “Bracket/Sensor installation”

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

Press

Simultaneously

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 op-

eration. 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 or Cadence , by pressing SET/AT button and S/S button
simultaneously. If Clock comes up to the upper display, Current Speed comes
down to the lower display and joins in the main function; in the same manner, if
Cadence comes up, Current Speed comes down.

*When Auto function is on, just push S/S button and the upper display changes from
"Current speed " to "Clock time " or “Cadence ”.

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.
