The EVO Abacus 9 & 12 Cycle Computers are devices designed to track various cycling metrics. They come with a cycle computer unit, a speed sensor, a speed magnet, a rubber contour grommet, a bracket, and four nylon ties for mounting.

Function Description:

The cycle computer displays current speed, average speed, maximum speed, trip time, distance, odometer readings (total distance, ODO1 for Bike 1, ODO2 for Bike 2 - Abacus 11 only), and calories consumed (KCal Mode). It also features a clock mode with 12/24-hour display and a low battery indicator. The Abacus 11 model includes a backlight function.

Important Technical Specifications:

• Operating Temperature (Receiver & Speed Sensor): 0°C to 40°C
• Storage Temperature (Receiver & Speed Sensor): -10°C to 50°C
• Battery (Receiver & Speed Sensor): 3 volt lithium 2032 cell
• Emitted Frequency (Speed Sensor): 122k±5%
• Weight: Receiver: 30.6 grams, Speed Sensor: 20 grams
• Timer Range: 0-29 hours, 59 minutes, 59 seconds
• Current/Average/MAX Speed Range: 0-99.9 KM/H or 0-62.4 Mile
• Trip Distance Range: 0-999.99 KM or 0-624.99 Mile
• Odometer Range: 0-99999 KM or 0-62499 Mile
• Wheel Size Acceptance: 100mm to 2,999mm

Usage Features:

Mounting:

1. Bracket Mounting: Use the nylon ties to secure the bracket to the handlebar or stem.
2. Computer Mounting: Place the cycle computer on the bracket and secure it by turning clockwise.
3. Speed Sensor Mounting: Mount the sensor to the front fork using nylon ties.
4. Magnet Mounting: Secure the magnet to a spoke on the front wheel using the included screw, ensuring it faces the speed sensor. The magnet must be within 2-3mm of the speed sensor for proper function. It's crucial to tighten the speed sensor properly to avoid interference with spokes.

Setting Wheel Size:

The wheel circumference needs to be determined for accurate readings. A wheel size chart is provided in the manual for nominal sizing.

Maintenance Features:

• General Cleaning: Bracket, magnet, and sensor band can be cleaned with water and mild soap.
• Battery Replacement: Unscrew the back cover of both the receiver and sensor. The (+) side should face up. Replace with a new CR2032 battery.
• Display Issues: If the display contrast changes or figures become faint, replace the battery. Consider changing both computer sensor and transmitter batteries simultaneously.
• Environmental Care: Avoid exposing the computer to extreme temperatures (cold or hot) or direct sunlight for extended periods.
• Sensor Check: Regularly check the position of the magnet and sensor. Keep them dry and free of dirt to ensure proper function.

Troubleshooting:

• Black/Light Display: Low battery or incorrect battery installation.
• Dark/Black Display: Unit is too hot; move to a shaded area.
• Slow/Struggling Operation: Unit is too cold; warm it up.
• Varying Data: Electromagnetic or high energy interference; move away from the source.
• Slow Data Display: Low temperature affecting display, but not function reading. Data will normalize with temperature rise.
• No Current Speed: Magnet and sensor distance needs to be adjusted to 2-3mm.

Important Health Notice:

Do not use the cycle computer with other medical/implanted electronic equipment (pacemakers, EKF, TENS, cardiopulmonary machines). Consult a doctor if severely ill or pregnant. Keep away from children due to batteries. Avoid common sources of interference (high voltage power lines, AC motor units, fluorescent lights, wristwatches, mobiles, computers) to prevent inaccurate readings.
