Quick guide from the manual

The Sigma Pure 1 and Pure 1 ATS cycling computers are delivered in a deep sleep mode. To activate the device for the first time, press and hold the SET or MENU button (depending on the model) for 5 seconds. The computer will then switch to active mode.

Installation

The computer can be mounted on either the stem or the handlebar. Ensure the bracket is securely fastened. For the sensor installation, ensure the magnet is correctly positioned relative to the sensor on the fork. If you are using the wired version, route the cable carefully along the frame. For the wireless version, ensure the transmitter is mounted within the required distance from the magnet.

Setup and Configuration

To ensure accurate speed measurement, you must set the wheel size according to your tire size. You can do this by selecting a predefined wheel size, calculating the size using the formula provided in the wheel size chart, or determining the value from the drawings in the chart. You can also set the unit of measurement (KMH or MPH) in the settings menu.

Troubleshooting

If you experience no speed display or incorrect speed, check the following:

• Ensure the computer is correctly fastened into the bracket.
• Check the distance between the magnet and the sensor.
• Verify that the magnet is correctly positioned in relation to the sensor.
