Most Echo T3 computers have a button on the face and a button on the bottom (or reverse side).
The Echo T3 cycle computer is a wired/wireless bicycle speed sensor and odometer. While the specific Echo T3 manual is often hosted on community-driven sites like Wikidot, the operational steps are largely identical across most Echowell Echo series models. General Setup Instructions
Initiate & Clear Data: Use a small pin to press the "All Clear" (AC) button on the back of the unit. This will reset the system and prepare it for new calibration data.
Select Units: Choose between KM/H (Kilometers) or M/H (Miles). Press the right button to toggle and the left button to confirm. Input Tire Circumference: Find your tire size on the sidewall (e.g., 700x23c).
Enter the corresponding 4-digit code (circumference in millimeters) using the buttons to increment each digit.
Tip: A standard 700x23c tire usually uses a setting of 2096.
Set the Clock: After tire setup, the display will move to the 12/24-hour clock setting. Set the time to ensure trip logs are accurate. Key Functions & Navigation Cycle through the modes by pressing the main button: SPD: Current Speed (always displayed at the top).
DST: Trip Distance (distance covered in the current session).
ODO: Total Odometer (total distance since the last battery change). TM: Elapsed Trip Time. AVS: Average Speed. MXS: Maximum Speed recorded. Troubleshooting Common Issues echo t3 cycle computer manual free
No Speed Reading: Ensure the distance between the spoke magnet and the sensor is 5mm or less. If the gap is too wide, the sensor won't trigger.
Faded Display: This usually indicates the battery (typically a CR2032) is low and needs replacement.
Data Not Clearing: To reset your current trip data (DST, TM, AVS) without resetting the total Odometer, press and hold both buttons simultaneously for 3 seconds while in one of those modes.
For a downloadable PDF version of similar Echowell models, you can refer to the Echowell Echo A3 Manual at Manua.ls, which uses an almost identical interface. Echo T3 Cycle Computer Manual - Jennifer Fox - Wikidot
Finding a free manual for the older Echo T3 cycle computer can be challenging, as official digital archives often omit legacy models. While the specific T3 manual is not hosted on a single primary blog, the following resources provide the necessary setup and calibration instructions. Manual & Setup Guides
Echo T3 Digital Archive: A blog post on Jennifer Fox's Wikidot specifically lists the Echo T3 Cycle Computer Manual for free reading and download.
Sheldon Brown Calibration Database: This is a highly reputable resource for older cyclometers. While it may list the "
" specifically, the calibration and button-press sequences (holding both buttons for 3 seconds to enter "Set" mode) are often identical across the Echo/Echowell T-series and J-series. Most Echo T3 computers have a button on
Echowell General Setup: Since Echo computers are often manufactured by Echowell, general manuals like the Echowell U4 Manual
on Scribd cover the same fundamental operations: setting wheel circumference, clearing ODO data, and battery replacement. Quick Setup Reference
If you have the device but no manual, these standard Echo/Echowell steps typically apply:
Initiate/Reset: Hold the Mode and Set buttons simultaneously for 3+ seconds to clear all data and start the setup sequence.
Select Units: Use the Mode button to toggle between Km/h and M/h.
Calibrate Wheel Size: Enter your tire's circumference in millimeters (e.g., 2050 for a 26 x 1.95 tire or 2136 for 700x28mm).
Set Clock: In Clock (CLK) mode, hold the left button for 3 seconds to enter 12h/24h selection. Installation Tips Echo T3 Cycle Computer Manual - Jennifer Fox - Wikidot
