care also to prevent any of them from falling.
• Do not use paint thinner or rubbing alcohol to clean the unit.
• Stop using the unit if you have skin irritation with the HR strap or electrode pad.
• Do not twist or pull strongly the heart rate sensor.
• The heart rate sensor may deteriorate due to long-term use.
Replace the heart rate sensor if it has frequent measurement errors.
• As a nature of liquid crystal displays, sunglasses with polarized lens may block the visibility.
2.4GHz digital wireless system
2.4GHz-frequency digital wireless technology, which is the same technology used for
wireless LAN, is used for both the speed/cadence integrated speed sensor and the heart
rate sensor. This technology practically eliminates interference from external noise and
cross-talk with other wireless computer users, and enables to store highly reliable data.
However, in a very rare occasions, objects and places may generate strong electromagnetic waves and interference, which may result in incorrect measurement:
• TV, PC, radios, motors/engines, or in cars and trains.
• Railroad crossings and near railway tracks, around television transmitting stations and
radar bases.
• Other wireless computers or digitally controlled lights.
Be sure to follow these instructions.
* Helpful tips are highlighted with asteriks.

Tire circumference
You can find the tire circumference (L) of your tire size in the chart below, or actually
measure the tire circumference (L) of your bicycle.
How to measure the tire circumference (L)
For the most accurate measurement, do a wheel roll out. With the tires
under proper pressure, place the valve stem at the bottom. Mark the
spot on the floor and with the rider's weight on the bike, roll exactly one
wheel revolution in a straight line (until the valve comes around again to the bottom). Mark
where the valve stem is and measure the distance in millimeter.
L mm
* For your reference, use the tire circumference chart below.
4. Set the sensor ID
Set the heart rate sensor ID and the speed sensor ID.
* This unit requires the sensor ID in order for the computer to receive signal from
the sensors.
* To check the sensor ID, heart rate sensor must be worn properly (page 9), and be
within 5 m from the bicycle with a speed sensor mounted (page 7).
* When performing ID Synch, make sure there is no other similar sensors in the
surrounding area. (It may pick up other sensor's ID)

Advance use of the real time lap data
For the real time lap data indicated in the lower display, the unit starts/stops measurement in sync with
the main time measurement; however, it resets and
restarts the data every time you press the LAP button.
This independent feature of lap time can be useful
also for intervals and sectional trials such as hill

climb section.
Countdown distance
The countdown distance feature displays the countdown distance to a
predetermined target trip distance, and notifies when it reaches zero.
When it reaches the target trip distance, the unit switches any measurement data to the countdown data, and notifies it by flashing the
numeric/dot display and an alarm sound.
Example of how the countdown distance is used
1. Entering the race event distance
For distance system events such as a road race and
century ride, enter the race event distance before the
start, and develop your strategy and pace based on the
countdown distance during the race.
2. Entering the destination sign distance
For touring, enter the sign distance whenever you encounter a destination sign
along the road, and develop your pace based on the countdown distance.
3. Entering the periodical target distance
Enter the periodical target distance for a week, month, or year to check your progress.
* The target trip distance is set from the menu screen “Setting the countdown distance”

When moving the computer from one sensor to another or to use a different HR chest
strap, this operation must be performed.
* This unit requires the sensor ID.
The computer cannot receive the sensor signal unless the sensor ID is synchronized properly.
* To synchronize the sensor ID, the heart rate sensor must be worn properly (page 9), and be near
the bicycle with a speed/cadence mounted (page 7).
* When searching the sensor ID, make sure no other sensors are in the area within 10 m radius.
For the Speed/Cadence sensor, it is also possible to press the Reset button on the sensor to

Heart rate training
This section is just a general overview of training with heart rate data. For more complete
information, there are books and websites with more in-depth information.
Generally, the heart rate increases during exercise, getting higher in conjunction with the
intensity of the workout. Measurement the rate of your heart beat is a good indicator of
the intensity of your workout. By setting target HR (heart rate) zones and sticking to preset exercises, you will be able to work out more efficiently. Before beginning a training
program, be sure to first consult a medical specialist or sports trainer.
1. Improving general fitness
Bicycling is one of the best activities to improve your general fitness. To improve your
overall fitness through bicycling, set a target heart rate zone from between 30% and 70%
of your maximum HR, depending on your physical strength. For best results, exercise
consistently in this zone for periods of at least 20-30 minutes, 3 or more times a week.
To obtain your target zone, see the table below, which illustrates the correlation between heart rate and training level. For beginners, it is recommended to start with the
level of 30% of your max. From this point, gradually increase the level according to
your fitness level and experience. Training at levels over 70% of your HR max will
focus more on anaerobic exercise, and less on aerobic exercise. Weight loss usually
occurs through longer rides (over 1 hour) at lower HR levels.

2. Training for competition
Measure your resting heart rate just after waking in the morning and your maximum
heart rate (perhaps during competition). Then set your target zone according to your
goal:
A) For recovery, endurance training, and weight loss :
60% - 70% (aerobic exercise)
B) For quality endurance and tempo training :
70% - 80% (aerobic exercise)
C) For increasing TT and race ability, and VO2 max :
85% + (anaerobic exercise)
D) For anaerobic capacity and sprinting :
92.5% + (anaerobic exercise)
• Training level (%) = x 100
• Target heart rate = (Maximum heart rate - Resting heart rate) x
Training level (%)
100
Resting heart rate
Your resting heart rate is usually the lowest recorded rate soon after waking up in the
morning.
Maximum heart rate
The following calculations are generally used: (220 - age) or (204 - 0.69 x age).
For more precise figure, consult a training specialist.
(Target heart rate) - (Resting heart rate)
(Maximum heart rate) - (Resting heart rate)
+ Resting heart rate
3. Use of the target zone
When the heart rate is out of the zone during the measurement, the computer sounds an
alarm and notifies the rider by flashing
The heart rate zone is selected from 4 predetermined zones.
For a training aiming at a heart rate of 140 to 160 bpm, select HR.ZONE:3 as shown below.
Then, the computer sounds an alarm when the heart rate falls below 139 bpm, or
rises above 161 bpm.
Once the target zone is set to On, the relevant data are recorded and the time in the
zone, time above the zone, and time below the zone and their percentages can be
viewed in the file view (page 24).
* You can enter any upper/lower limit to each zone.
* For the target zone, you can select OFF or Zone 1 to 4, and change the upper/lower
limit from the menu screen “Setting the target heart rate zone” (page 34).
* On/off of the alarm sound is selected from the menu screen “Setting sound” (page
33).
