This document describes the SD-589 Bicycle Computer, a device designed to track various cycling metrics.

Function Description

The SD-589 Bicycle Computer offers 19 distinct functions to monitor and enhance your cycling experience:

SPD (Current Speed): Displays your real-time cycling speed.
ODO (Odometer): Tracks the total distance traveled, with a range of 0 to 99999 km/m.
DST (Trip Distance): Measures the distance covered during a single trip.
MXS (Maximum Speed): Records the highest speed achieved during a trip.
AVS (Average Speed): Calculates the average speed for a single trip.
TM (Elapsed Time): Measures the duration of your cycling trip.
CLK (Clock): Displays the current time in either 12H or 24H format.
TMP (Temperature): Shows the ambient temperature, with a range of -10°C to 70°C.
SCAN: Automatically cycles through DST, MXS, AVS, and TM displays every four seconds.
"+" "-" Comparator: Indicates whether your current speed is higher or lower than your average speed.
SETTING TYRE CIRCUMFERENCE: Allows you to input the circumference of your bicycle's tire (0-9999mm) for accurate speed and distance calculations.
SETTING SPEED SCALE: Enables selection between kilometers (km) and miles (m) for speed and distance units.
MAINTENANCE ALERT: Notifies you when scheduled maintenance is due based on set mileage intervals.
SETTING THE LAST VALUE OF ODOMETER / ODO: Allows manual input or adjustment of the odometer reading.
COMPUTER LOW BATTERY INDICATOR: Alerts you when the computer's battery is low.
WIRELESS WAKE UP: The computer automatically wakes up from sleep mode upon detecting a signal or button press.
AUTO BACKLIGHT: The backlight automatically activates in low-light conditions.
BACKLIGHT IS LONG BRIGHT: Allows for continuous backlight illumination.
AUTO ON/OFF: The device automatically turns on and off.

Important Technical Specifications

Temperature Measurement Range: -10°C to 70°C.
Odometer Range: 0 to 99999 km/m.
Trip Distance Range: 0.01 to 9999 km/m.
Trip Time Range: 0:00:00 to 9:59:59.
Speed Accuracy: +/- 0.1 km/h (mile/h).
Tire Circumference Input Range: 0 to 9999 mm.
Sensor-Magnet Distance: The distance between the speed sensor and the magnet should be 3-5mm for optimal performance.
Computer-Sensor Distance: The computer and sensor should be installed on the same side of the fork, with a distance of less than 60cm between them.
Battery Type: CR2032 Battery (for the computer).

Usage Features

Installation:

Computer Battery Installation: Ensure the positive (+) pole faces the battery cover when inserting the CR2032 battery. If the LCD shows strange figures, remove and reinsert the battery.
Mounting Shoe: Align the computer unit with the mounting base and rotate clockwise to lock it. Attach the mount base to the handlebar at the desired location using the threaded strap and nut.
Speedometer Sensor and Magnet: Attach the speedometer sensor to the front fork using ties, ensuring the arrow on the sensor points towards the magnet. The magnet should be secured to a bicycle spoke, with a 3-5mm gap between the sensor and magnet. The magnet is designed for spokes less than 2mm thick.
Speed Function Check: To verify proper speed function and sensor alignment, spin the front wheel while the computer is in speed mode. Adjust the sensor and magnet positions if the signal is weak or absent.

Parameter Settings:

Wheel Size Input: Reinstall the battery or press MODE + SET for 4 seconds to enter wheel size setting. The screen will display "2060" with a blinking digit. Use the MODE key to change the flashing value and the SET key to confirm and move to the next digit. Input your tire circumference (0-9999mm) based on the provided table.
Unit Setting (km/mile): Press the MODE button to select between kilometers (km) and miles (m). Press the SET button to confirm and proceed to Maintenance Alert setting.

Mode Navigation:

Press the MODE button to cycle through different functions (e.g., ODO, DST, MXS, AVS, TM, SCAN, CLK, TMP).

Setting Specific Functions:

Clock (12H/24H): In clock mode, press and hold SET for 4 seconds to enter 12/24H format setting. Press SET to switch formats. Use SET to select Hour/Minute and MODE to change the flashing figure. Press SET to confirm.
Odometer Last Value: In ODO mode, press and hold SET for 4 seconds. Use MODE to change the flashing figure and SET to confirm each digit to set the desired ODO value.
Temperature Unit: In temperature display mode, press and hold SET for 4 seconds to switch between Celsius (°C) and Fahrenheit (°F).

Data Clearing:

In DST, MXS, AVS, or TM mode, hold the SET button for 4 seconds to clear all data for that specific mode.

Backlight Control:

Auto Backlight: Activates automatically in insufficient light. Press any button to turn on the backlight for 5 seconds.
Long Bright Backlight: Press and hold the MODE key for 4 seconds to turn on continuous backlight. Repeat the action to turn it off.

Sleep Modes:

Sleep Mode: The computer enters sleep mode when there is no signal input or key press. The clock is retained, and values before sleep are remembered.
Deep Sleep Mode: To enter deep sleep mode, press and hold MODE + SET for 6 seconds. The screen will display "SLEEP." The computer will automatically enter deep sleep mode if there is no operation within 7 days. To wake up from deep sleep, press any key.

Maintenance Features

Maintenance Alert:
- To set the maintenance alert, press the MODE button to choose from 200/400/600/800 km/mile (default is 200km/mile). Press SET to confirm.
- When the ODO reaches the set maintenance alert value, a wrench symbol will appear on the screen.
- To clear the alert, press both SET and MODE buttons simultaneously.
Computer Low Battery Indicator: A dedicated icon will appear on the screen to indicate when the computer's battery is low, prompting replacement of the CR2032 battery.
Troubleshooting Guide: The manual provides a table of common malfunctions and their corresponding solutions:
- No speed reading: Check for incorrect magnet/sensor alignment.
- Inaccurate value indicated: Verify correct wheel circumference input.
- Slow display response: Indicates temperature exceeding operating limits (0°C-55°C).
- Black display: Suggests the temperature is too high or the unit is in direct sunlight. Allow the unit to cool down.
- Weak display: Check for poor battery contact or a dead battery.
- Irregular figures displayed: Remove and reinstall the battery after 10 seconds.
Battery Replacement Note: Before replacing the battery, it is recommended to write down your current mileage (ODO) and re-enter it after battery replacement to maintain accurate total distance tracking.
