Introduction
Thank you for purchasing the CATEYE V2c.
The V2c is a high-performance computer for riders who wish to train extensively and
analyze their data.
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. This technology practically eliminates interference from external noise and cross-talk with other wireless computer users, providing you with stress-free riding.
Read this instruction manual thoroughly and understand the functions of the product
before using it.
Keep it in a safe place for future reference.

Proper use of the CatEye V2c
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 V2c.
* Helpful tips are highlighted with asteriks.
Warning!!! :
• Do not concentrate on the data while riding. Always be sure to ride safely.
• Do not leave any battery within the reach of children, and dispose of them correctly. If
a battery is swallowed, consult a doctor immediately.
Caution:
• Regularly check the positions of the magnets and the speed/cadence sensors and make
sure that they are securely mounted. Tighten it firmly if there is any looseness.
ENG
• Avoid leaving the main unit / wireless sensor in direct sunlight for extended periods of time.
• Do not disassemble the computer, or speed sensor.
• Do not subject the computer, or speed sensor to strong impact; take care also to prevent any of them from falling.
• Do not use paint thinner or rubbing alcohol to clean the unit.
• As a nature of liquid crystal displays, sunglasses with polarized lens may block the visibility.
2.4GHz digital wireless system
2.4GHz-frequency digital communication technology, which is used for wireless LAN, is
adopted for both the speed/cadence integrated type speed 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.

2-2. Mount the magnet
1. Loosen the setscrews both on the SPEED side
and CADENCE side of the speed sensor, and turn
the sensor to the angle as shown on the right.
2. Temporarily secure the wheel magnet to the
spoke so that it faces the sensor zone on the
SPEED side.
3. Temporarily secure the cadence magnet inside
the crank with nylon ties, so that it faces the
sensor zone on the CADENCE side.
* When the speed sensor is not positioned ap-
propriately in respect to the two magnets (in both
Steps 2 and 3), move the speed sensor back
and forth so that it is positioned properly.
After you move the speed sensor, adjust the
position so that the two magnets face the relevant sensor zone.
4. After adjustment, tighten the nylon ties firmly
to secure the speed sensor.

1. Adjust the distance between the wheel magnet
and the SPEED side of the speed sensor to be
about 3 mm. After adjustment, tighten the
setscrew on the SPEED side.
2. Adjust the distance between the cadence
magnet and the CADENCE side of the speed
sensor to be about 3 mm. After adjustment,
tighten the setscrew on the CADENCE side.
