Cateye VELO WIRELESS CC-VT230W - Cyclocomputer Manual

Mounting the computer

Mount the bracket

• When mounting on stem
  
  
• When mounting on handlebar
  

When mounting the bracket on a handlebar, adjust the angle of the bracket so that the back of the computer faces the speed sensor when the computer is attached.

Mount the speed sensor

• Mounting on right front fork
  
  
• Mounting on left front fork
  

Mount the speed sensor in a position where the distance from the computer to the speed sensor is within the signal range.

Mount the magnet

Adjust the speed sensor and the magnet

The magnet passes through the speed sensor zone.

The clearance between the speed sensor and the magnet is within 5 mm (3/16").

* The magnet may be mounted at any position on spoke as long as attachment conditions are satisfied.

Attach/detach computer

Test operation

After attaching the computer, rotate the front wheel gently to check that current speed is displayed on the computer.
If the speed is not displayed, refer to the attachment conditions in steps 1, 2, and 4 again.

Setting up the computer

When using the computer for the first time or resetting it to its factory default settings, clear all computer data following the procedure below.

Clear all data

Press the AC button on the back of the computer.

* All data is deleted and the computer is reset to its factory default settings.

Select the measurement unit.

Select "km/h" or "mph".

Select the tire size.

Simple setting:
When MODE is pressed, 26"→ 700C → 27"→ 27.5"→ 29"→ 205 [ ] → 16"→ 18"→ 20"→ 22"→ 24" and 26" will appear, in this order. Select the tire size (inch) of your bicycle.

Advanced settings

(For more accurate measurement):
Display 205[ ] on the screen, and press and hold MODE to enter the tire size of your bicycle in cm. Pressing MODE changes the value, and pressing and holding MODE moves to the next digit.
* For details on the tire circumference, see "Tire circumference".

Set the clock

Each time the MODE button is pressed and held, settings switch from time display mode, to hours, to minutes.
* When 12h is selected, A (AM) or P (PM) is displayed at the top of the screen.

Press MENU to complete setup.

Setup is completed and the computer switches to the measurement screen. For instructions on how to start measurement, refer to "Starting measurement".

Tire circumference

Tire circumference can be determined by either of the following two methods:

• Measure the actual tire circumference (L) After ensuring that the tire pressure is appropriate, sit on your bike, roll it forward so that the tire makes one full revolution (use the valve or other marking as a reference), and measure the distance traveled on the road.
  
  
• Tire size chart
  * The tire size or ETRTO code is indicated on the side of the tire.

Starting measurement

[Measurement screen]

Sensor signal icon
Flashes in sync with a sensor signal.

Pace arrow
Indicates whether the current speed is faster ( ) or slower ( ) than the average speed.

Current speed
0.0 (4.0) – 105.9 km/h
[0.0 (3.0) – 65.9 mph]

Switching current function

Pressing MODE switches the current function displayed at the bottom of the screen.

*1: Av (Average Speed) displays .E instead of the measurement value when Tm (Elapsed Time) exceeds approximately 27 hours or Dst (Trip Distance) exceeds 999.99 km. Reset the measurement data.

*2: Calorie consumption is a cumulative value based on speed calculated at one second intervals. Values for calorie consumption per hour are shown below. Use the values in this chart as a reference.

Starting/stopping measurement

Measurement starts automatically when the bicycle moves. During measurement the measurement unit (km/h or mph) flashes.

Resetting data

Pressing and holding the MODE button when on the measurement screen resets all measurement data to 0 (excluding Odo).

Power-saving function

If the computer does not receive any signal for 10 minutes, the power-saving screen is activated and only the clock is displayed. If MODE is pressed or a sensor signal is received while the powersaving screen is activated, the computer returns to the measurement screen.

* If the computer is left on the power-saving screen for 1 hour, SLEEP is displayed. When the computer is in this state, you can return to the measurement screen by pressing the MODE button.

Changing settings

[Menu screen]

On the measurement screen, press MENU to go to the menu screen. Various settings can be changed on the menu screen.

* After changing settings, always press MENU to confirm changes.
* When the menu screen is left on for 1 minute, the computer returns to the measurement screen.

Warning / Caution

• Do not concentrate on the computer while riding. Always ride safely.
• Mount the magnet, sensor, and bracket securely, and check them periodically to ensure that they are not loose.
• If a battery is swallowed accidentally, consult a doctor immediately.
• Do not leave the computer in direct sunlight for a long period of time.
• Do not disassemble the computer.
• Do not drop the computer. Doing so may result in malfunction or damage.
• When cleaning the computer and accessories, do not use thinners, benzine, or alcohol.
• Risk of explosion if battery is replaced by an incorrect type. Dispose of used batteries according to local regulations.
• The LCD screen may be distorted when viewed through polarized sunglass lenses.

Wireless Sensor

The speed sensor is designed with a maximum signal range of 70 cm (27"), to reduce the chance of interference. (The signal range is intended to serve as a rough guide only.) When handling the wireless sensor, note the following:

• Signals cannot be received if the distance between the speed sensor and the computer is too large.
• Signal range may be shortened due to low temperature and flat batteries.
• Signals can be received only when the back of the computer is facing the speed sensor.

Interference may occur, resulting in malfunction, if the computer is:

• Near a TV, PC, radio, or motor, or in a car or train.
• Close to a railroad crossing, railway tracks, TV transmitter station, or radar station.
• Used with other wireless devices or certain battery-powered lights.

Frequency Band: 19 kHz
Radiated Power: −3.8 dBA/m (at 10 m)

Replacing the battery

• Computer
  When the display becomes dim, replace the battery.
  Insert a new lithium battery (CR2032) with the (+) side up.
  * After replacing the battery, always follow the procedure described in "Setting up the computer".
  * If you make a note of the total distance value before replac-ing the battery, you will be able to continue from the same total distance by entering it after replacing the battery.
  
  
• Speed sensor
  When the speed is not displayed even after adjusting correctly, it is time to replace the battery.
  Insert a new lithium battery (CR2032) with the (+) side up and close the battery cover firmly.
  * After replacing the battery, adjust the position of the magnet relative to the speed sensor as described in "Mounting the computer" step 4.
  

Troubleshooting

The sensor signal reception icon does not flash. (Speed is not displayed.)

• Is there too much clearance between the speed sensor and the magnet?
  (Clearance should be within 5 mm (3/16").)
• Does the magnet pass through the sensor zone correctly?
  Adjust the position of the magnet and/or the speed sensor.
• Is the computer mounted at the correct angle?
  Ensure that the back of the computer faces the speed sensor.
• Are the computer and the speed sensor mounted at the correct distance apart?
  (Clearance should be from 20 to 70 cm (8" to 27").)
  Ensure that the speed sensor is within range.
• Is the computer or speed sensor battery flat?
  * Battery performance diminishes in winter.
  If the computer reacts only when it is close to the speed sensor, the problem may be due to weak batteries.
  Replace the batteries with new ones as described in "Replacing the battery".

The display remains blank when the button is pressed.

• Replace the computer battery as described in "Replacing the battery".

Incorrect data appear.

• Clear all according to the procedure described in "Setting up the computer".

Main specifications

* Average value when used at temperature of 20°C with computer and sensor mounted 65 cm apart.
* Life of pre-installed battery may be shorter than indicated above.

* Specifications and design are subject to change without notice.
