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.

Maintenance

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" (page 5). If you make a note of the total distance value before replacing 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" (page 4) step 4.

Diagram Description: Shows how to open and close the battery compartment for the computer and speed sensor, indicating the CR2032 battery and the [+] terminal.

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" (page 5).
