Note: An integrated memory chip saves all total values and settings when changing the battery, preventing data loss.

3.2 Mounting the Cyclocomputer and Transmitters

1. Handlebar/Stem Mount: Secure the mount to your handlebar or stem using the provided O-rings or cable ties.
2. Speed Transmitter: Attach the speed transmitter to the front fork, ensuring it aligns with the spoke magnet. The distance between the transmitter and magnet should be approximately 5-10 mm.
3. Spoke Magnet: Fasten the magnet to a spoke on your front wheel.
4. Cadence Transmitter (if applicable): Mount the cadence transmitter to the chainstay, aligning it with the cadence magnet on the crank arm.
5. Heart Rate Transmitter (if applicable): Wear the heart rate chest strap directly on your skin, just below your chest muscles.

3.3 Initial Settings

Upon first use or after a battery change, you will need to configure basic settings:

• Language: Select your preferred language.
• Units: Choose between kilometers (km/h) or miles (mph) for speed and distance.
• Wheel Size: Accurately measure and input your wheel circumference for precise speed and distance readings. Refer to your bicycle tire for circumference values or measure manually.
• Time Format: Set 12h or 24h format.
• Personal Data: Input age, weight, and gender for accurate calorie and heart rate zone calculations.
