Basic operation of the computer ENG 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 cadence.
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, 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 ENG Upper and middle display data 1 1 Current speed Displays the current speed. Updated every second. 2 Cadence 2 Displays the number of pedal rotations per minute. Updated every second. M1/+ 3 3 Average speed *1 Displays the average speed after the start of measurement. 4 Average cadence *2 4 Displays the average cadence after the start of measurement. * The average will not be reflected when you stop pedaling.
Lower display data Elapsed time Displays the elapsed time from the start of measurement to the 1/10 second. When it exceeds 99:59’59”, it repeats from 00’00”0. * When the elapsed time reaches 1 hour, the 1/10 second is not displayed. M2/- Trip distance Displays the trip distance from the start of measurement. M2/- Countdown distance (page 20) Displays the countdown distance to the target distance to the target distance.

Use of the target zone When the target cadence zone is turned On, cadence is monitored against set zone range. When the cadence is out of the zone during measurement, the computer sounds an alarm and notifies a rider by flashing . For training aiming at a cadence of 80 to 120 rpm, set the lower limit to 80 and upper limit to 120. Then, the computer emits an alarm when the cadence falls below 79 rpm, or rises above 121 rpm.
Trouble shooting Trouble on display Trouble Display motion becomes slower. Check Items Is the surrounding temperature low (below zero degree Celsius or 32 degrees Fahrenheit)? Remedy Temperatures below freezing may result in slower screen response. Data is not affected. Flashes on the screen. The remaining battery capacity for the computer is low. No displays appear. Is the battery for the computer empty? Replace it with a new battery (CR2032) immediately.

Turn off the auto-mode. (See “Setting the auto-mode” on page 31.) The speed/cadence sensor ID synch failed. The battery for the speed sensor is possibly depleted.
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, or speed/cadence sensor 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, and speed/cadence 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.
