Proper use of the CatEye V3n ENG Observe the following instructions for safe usage. The meaning of icons in this manual: Warning!!! : Sections marked with these icons are critical for safe use of the device. Be sure to follow these instructions. Caution : Important cautionary notes on the use and operation of the V3n. * Helpful tips are highlighted with asteriks. Warning!!! : • Pace maker users should never use this device. • Do not concentrate on the data while riding. Always be sure to ride safely.
Automatic recognition of the speed sensor ID The speed sensor has its own ID, and the computer measures in synchronization with the ID. Two speed-sensor IDs can be registered to one computer, which can automatically identify two speed sensors once their IDs are registered in advance. As a tire circumference is set to the speed sensor ID, wheel selection by manual operation is no longer required, which was necessary with conventional units.

Formatting/Restarting operation There are two different computer set-up operations; formatting and restarting operations. Follow the appropriate one depending on the situation. Formatting The formatting operation is performed at initial purchase, or to delete all measurement data and reset all to default. * The sensor ID is not deleted. Restarting The restarting operation is performed after you replace batteries, or when an error is displayed.
Basic operation of the computer 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.
Starting/Stopping the measurement The speed unit (km/h or mph) flashes during measurement. Initially, the auto-mode function which starts or stops measurement automatically in sync with the bicycle motion is ON. Auto measurement is switched to manual measurement and vice versa by ON/OFF operation in the auto-mode. * For setting the auto-mode, refer to the menu screen “Setting the auto-mode” (page 35).
To reset the measurement data (excluding the total time, total distance, date, and clock) and the lap data, simultaneously press the SSE button and the M1/+ or M2/- button on the measurement screen. * Resetting the measurement data saves the data automatically on a file (page 26). * The screen will freeze for about 2 seconds after resetting and button operation is disabled; however, all measurements are operating normally. * The countdown distance (C.D.DST→) returns to the value you set.

Pace function 2 types of pace arrow icons for the current speed and the heart rate are displayed on the screen. These arrow icons indicate whether the current speed (heart rate) is above or below the average speed (average heart rate). Current speed Appears when the current value is above the average. Appears when the current value is below the average. No When the current value is equal to the average, or arrows zero.
The recorded lap data is saved to a file when you perform the resetting operation (page 19), and can be viewed on the menu screen “File view” (page 26). * Pressing the LAP button while the total number of laps reaches 99 displays the lap data, but “--” appears in place of the lap number indicating further recording is impossible. * One lap per file is used even when there is no lap data. Therefore, the total number of laps is the sum of the total number of laps in all files and the number of files.
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 computer switches any measurement data display to the countdown display, and notifies it by flashing the dot display and an alarm sound. Example of how the countdown distance is used 1.

Heart rate training general fitness 1 Improving 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.
for competition 2 Training 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.
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 26).
Trouble shooting If a malfunction occurs, check the following before contacting CatEye or your retailer for repair or service. Trouble on display Trouble Display motion becomes slower. Flashes on the screen. “STOP!” lights up. No displays appear. Meaningless display appears.

The remaining battery capacity for the computer is low.
The heart rate is sometimes zero and sometimes measured. Moving the main unit away from your body will prevent measurement of the heart rate. Check Items Have you checked the sensor ID? Is the computer ID Synch’ed with somebody else’s sensor? Is the Heart rate sensor icon off ? Remedy Check the speed sensor ID (page 32) for HR (heart rate sensor). If the Heart rate sensor icon is off , the computer cannot receive the Heart rate data. Press the M1/+ or M2/- button once to turn on the icon.

No measurement starts even while riding. The heart rate sensor (speed sensor) ID check failed. Lap data cannot be stored. Abnormal values appear. In menu mode, cannot change settings. Measurement data cannot be stored on the file view. ENG-44 Remedy Replace it with a new battery (CR2032).
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.
