1Getting started with Cycling Computer
1-1Before use
1. When installed on a bicycle this device can display the speed,
number of laps and cadence rate. It can also help you to monitor
your training output during a fitness session based on your
gender, age, body weight, height and maximum heart rate. It will
also measure the time used and calories burned. This device
helps you to progressively realize your dreams of better physical
performance and an improved physique.
2. The device has speed, lap and heart rate sensors built in that
provide readouts of cycling speed, cadence, and real time heart
rate.
3. When using the device for the first time and after battery changes
or resetting, please adjust the different sensors and enter your
personal information to ensure data accuracy. Please refer to User
Setting 2-3, Page 14 for details.
1-2 Steps to wear the transmitter
The Heart Rate Transmitter Belt reads your real-time heart
rate and transmits this to the cycling computer. Please refer to
the following steps to wear the Transmitter before you start to
exercise.
1. Fix the hook on one side of the band to the end of the chest strap.
2. Adjust the length of the band so the chest strap fits comfortably on
your body and won’t slip or loosen during training.
3. Wet the conducting pads on both sides of the chest strap fully.
4. Adjust the strap so that the Logo faces away from your chest.
Move the strap up to just under your pectorals and then hook the
other end up with the band.
5. Change the chronograph to BIKE MODE and check if the heartbeat
symbol is displayed as a regular rhythm. If the signal is steady
the chronograph will detect your heartbeat and display it on the
monitor within 15 seconds.

1-3 Know and customize your maximum training output
The chart below shows the heart rate level using %HR max. HR
max = 220 - Age with every 10 years of age as an age zone. This
chart is a reference for appropriate training output using the heart
training mode.
• The unit for heart rate is bpm (beats per minute), or heartbeats per
minute.
• Maximum heart rate = 220 －age. If your age is 20, then 220-20 =
200 bpm, and your maximum heart rate is 200 bpm.
• Maximum heart rate (maximum heart rate, MHR, or HRmax) refers
to the maximum heart rate for optimizing exercise or stamina. It is
often used as the prescribed index for training output in order to
find the THR. The most direct and accurate method of measuring
the maximum heart rate is to have this done by a doctor or
professional. An Exercise Stress Test is conducted and monitoring
is done by an electrocardiograph (ECG). Or you can use the
simple age formula to calculate your personal maximum heart rate.

6
繁中
• Target heart rate ＝training output (%) × maximum heart rate (HRmax).
• The target heart rate (THR) or training heart rate is used to find
the ideal rate for the optimal performance of aerobics to maximize
the benefit to your heart and lungs. You can find your own upper
and lower range target heart rate using the maximum heart rate
formula (%HRmax).
• In general, for persons with less than optimal health, it is
recommended that the low-strength target heart rate range be set
at 60% or below.
This table has six training programS of exercise intensity heart rate zone:
• Note 1: The 40-220 range is the normal CB100 setting range, but
the range values can be user defined. The graph will show the
strength of the training according to the value configured.
• Note 2: If the user defined training output is above the 90-100%
range, it is recommended that the Time Sustained should be less
than 5 to avoid sports injury.

2 Using the Cycling Computer for the first time
2-1Installing the Cycling Computer :
Either on the Handlebar or on the Handlebar Stem
1. First , screw the Bike Mount and handlebar clamp connector base together
tightly.
2. And then use the ties to secure the device to the Handlebar or Handlebar
Stem . Make sure the handlebar moves freely before securing .
3. Slide the Cycling Computer into the socket of the Bike Mount until you
hear a click sound , make sure the Cycling Computer is in the right
position and will not fall off.
4. To remove the Cycling Computer : press the lever of the Bike Mount ,
push the Cycling Computer out of the Bike Mount from the other side.
2-2 Installing the Sensors
2-2-1 Installing the Speed Sensor (SPEED) : Install the Speed Sensor on
the same side of the Cycling Computer . The Speed Sensor should form a
90angle with the Cycling Computer within a maximum distance of 50cm /
1.6404ft.
1. Use the ties to fasten the Speed Sensor along with the Rubber Pad on the
front fork of the bike, ALATECH logo faces outward.
2. Then secure the magnet to a spoke of the front wheel, the magnet should
face the Speed Sensor. Adjust the magnet position to be as high as the
Speed Sensor and in maximum distance of 5mm / 0.19685ft. between
each other.

If there is no sense of the signal or less grid showed, then adjust
the relative position of the magnet and Speed Sensor.
2-2-2 Installing the Cadence Sensor (CADENCE) : Install the
Cadence Sensor at the same side of the Cycling Computer , the
maximum distance from the bevel angle of both is 80cm / 2.6247ft..
1. Use the ties to fasten the Cadence Sensor along with the Rubber Pad
on the down tube of the bike, ALATECH logo faces outward. ( For Small
Wheel Bike or Folding Bike, fasten the device on the seat tube. )
2. Then secure a magnet on the inside of the crank, ALATECH logo faces to
the Cadence Sensor. Adjust the magnet position in a distance of 5mm /
0.19685ft from the Cadence Sensor, make sure there is no collision while
pedaling.
3. Finally, turn the pedal, enter to the screen of BIKE SET _Cadence Coding
of the Cycling Computer, and see if the signal showed at 3~4 grids. (See P.
? for the Steps of the signal interpretation. )
4. If there is no sense of the signal or less grid showed, then adjust the
relative position of the magnet and Cadence Sensor.
Note :
• Cut off the extra length of the ties to avoid any danger while riding.
• The receiving distance could be increased or decreased due to the
installation position, the position of the Sensors or Cycling Computer can
be adjusted slightly.
• Before riding, you are requested to enter the tire size of the bike
i n the
setting mode. For details about configuration, refer to 2-3-5 Bike

Percentile Value for Maximal Aerobic Power chart
The oxygen uptake index will increase as your stamina increases
and decrease as you get older. Generally, world-class athletes
have a higher aerobic uptake index. Studies show that when the
aerobic uptake index falls below the 20th percentile, it reflects a
sedentary lifestyle without much exercise that may increase the
amount of free radicals inside the body, which is harmful to your
health. Please compare your aerobic uptake measured by the
chronograph with the chart below and learn about your ability for
maximal oxygen uptake.

Maximal Aerobic Power can improve with training and decrease with age, world class
athletes typically have high VO2max. Research suggests that the VO2max below the 20th
percentile for age and sex, which is often indicative of a sedentary lifestyle, is associated
with an increased risk of death from all causes.
You can compare your own VO2max value measured by this watch with the reference list
on page 20 for better understanding of your health status.

• This chart can memorize two sets of bike values and the setting methods
for both are the same.
• To select between BIKE1 and BIKE2, highlight a bike and press the B
key Mode to go back to Watch Mode and confirm whether icon or is the
desired bike. If the sensor coding time runs over 4 minutes, the screen will
display coding fail.
• Note 1: Installing on standard bikes (road bike/mountain bike/folding bike)
(see 2-2) with regular methods should display a signal strength in the
middle range. For signals over the standard or not reaching the standard,
the installation location must be adjusted to enable optimal signal display
(refer to the chapter on installing the sensor).
• Note 2: If only one bar shows when the Cadence sensor is coding, it
means that the signal is weak and cannot be used normally. If all the bars
show (“ ＂), it means the signal is too strong and could interfere with
the signal from the chest strap. It is advisable to adjust the angle and
distance until the display shows 3 or 4 bars.

How to measure the diameter of the front wheel
To get the necessary wheel data, follow the steps below:
1. Set the bike upright and use a tape measure
to determine the diameter of the wheel.
2. Multiply the diameter by 3.14 to get the
circumference.
3. Enter the value into the Chronograph.
4. Press B or E to exit or enter the
next setting screen.
