Basic operation of the computer Functions on the measurement screen The measurement screen displays 4 different types of data, which are switched by pressing the M1/+ and M2/- buttons. The display data are as follows. Upper display data Displays the data related to the speed. Middle display data Displays the data related to the heart rate. Displays the data related to the cadence.
ENG Starting/Stopping the measurement Initially, the unit starts or stops measurement automatically in sync with the bicycle motion. This is called auto-mode function. “km/h” or “mph” flashes during measurement. The total distance, maximum speed, maximum heart rate, and maximum cadence are updated independently of stating/stopping measurement. Auto-mode function When the auto-mode is turned on ( lights up), the unit detects the wheel spinning, and starts/stops measurement automatically.
Measurement screen Upper and middle display data 1 Current speed 1 Displays the current speed. Updated every second. 2 Heart rate Displays the heart rate in real time. Updated every second. 2 3 3 Cadence Displays the number of pedal rotations per minute. Updated every second.

Heart rate training 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.
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.
ENG 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.

Replacing battery Warning!!! : Safely dispose of the old batteries, and do not place them within reach of children. If a battery is swallowed, consult a doctor immediately. * When any battery for the computer, heart rate sensor, or speed sensor is depleted, we recommend replacing all batteries at the same time. * The battery life shown in this manual is not definitive and it varies depending on the use environment. * The battery cover sealing is critical to maintain the waterproof feature.
Maintenance Perform the daily care according to the following instructions. • Regularly check that the positions of the magnets and sensors are correct, and they are secured firmly. • When the computer, heart rate sensor, and speed sensor are dirty, wash them with water or wipe them with a soft cloth dampened with diluted neutral detergent, then wipe with dry cloth. Do not use solvents such as benzine or rubbing alcohol as they may damage the surfaces.
