Introduction Congratulations on having chosen the cycle computer with altimeter functions from ECHOWELL. The easy operation of your new Echo-a1 or Echo-a2 will let you enjoy much fun from riding. Please read this manual carefully before using the device to get familiar with the operation logic. The altitude calculation of this cycle computer works by measuring the atmospheric pressure.
There is a highly sensitive pressure sensor inside each Echo-a1 or Echo-a2 cycle computer, and there is a hole at the bottom of each main unit for measuring the pressure. You should always keep the hole clean to avoid incorrect measurement and must not poke a needle or any pointed article into it to avoid damage. The atmospheric pressure measured by the sensor will be converted into current altitude. After using your Echo-a1 or Echo-a2, you are sure to get a lot of fun from riding with it.
Using Your Computer 1.Main Unit Setup 1. Initiation of Main Unit: 1. Before normal operation, initiate the main unit and select units as stated below: 1-1. Push buttons A, B, C simultaneously for 3 seconds, and you'll see the auto-testing display. 1-2. Press any button to quit auto-testing display, and then select units of temperature, altitude and distance. 1-3. Press the C button to quit unit selection and enter General Mode. 2. Timing to initiate the main unit and select units is as listed below: 2-1.
The following is the General Mode Display during riding for reference: 7
2. Overview of Button Operation This computer includes three major display modes as shown below: Data Setting Mode, General Mode, and Altitude Calibration Mode. In this section, you'll learn the function of each button in each mode. The following text lets you know how to use the buttons to operate the computer step by step. 1. In Data Setting Mode: Tips: 1. The buttons you'll use in Data Setting Mode: A, B, C. 2. Button for entering or quitting Data Setting Mode: C 3.
setting. Button C: 1. In General Mode, press the C button to enter Data Setting Mode. 2.In Data Setting Mode, press the C button to exit and return to General Mode. Button D: No function. How do you enter Data Setting Mode after initiating the computer? After initiating the computer by pressing the A, B, C buttons at the same time for 3 seconds, press any button to quit auto-testing display, and then select units. After unit selection, press the B button for 2 seconds to enter Data Setting Mode. 2.
Button D: Altitude Calibration Mode. Press the D button to switch to Bike 1 or Bike 2. 3. In Altitude Calibration Mode: Tips: 1.The buttons you'll use in Altitude Calibration Mode: A, B. 2.Buttons for entering or quitting Altitude Calibration Mode: A+B (3's) 3.Buttons for quickly resetting the current altitude to zero: A+B (1's) Buttons A+B: 1. In General Mode, push A and B buttons for 3 seconds to enter Altitude Calibration Mode. 2.

How do you measure the wheel circumference yourself? Roll the wheel until the valve stem is closest to the ground and mark the corresponding spot on the floor as the first point. Next, roll the wheel forward until the valve stem is closest to the ground once again. Mark the corresponding spot on the floor as the second point. Then measure the distance between both points, using the unit of millimeter. The distance equals your wheel circumference. 1.
4. Basic Setting & Operation Tip for Data Setting : 1. Press the A button to change the value of a flickering digit. Press the B button to move to the next digit in a loop. 2. Press and hold the B button for 1 second to move to the next setting when the current setting is finished. 3. If the computer is idle during Data Setting Mode for 20 seconds, it'll automatically return to General Mode.
5. General Display The display of General Mode looks different in different phrases as shown below: 1. Put the main unit onto the bracket, and the main unit will automatically start measuring the speed and cadence. 2. The main unit will automatically enter Sleep Mode in 15 minutes once it doesn't receive any signals from the bike. 3. Only current time is displayed when the computer is in Sleep Mode (Power-Saving Mode.) 4.
6. Battery Replacement 1. When the low battery indicator is shown on the display, replace the battery with a new one A.S.A.P. 2. The positive (+) pole of the CR2032 battery must face the battery cap. 3.Press buttons A, B, C for 3 seconds to initiate the main unit. Attention: When there's the low battery symbol on the screen, we suggest that you replace the battery with a new one A.S.A.P. Otherwise, the altitude measurement result may be incorrect, and the new data may be lost.
7. General Mode Display When you are riding with the computer, some functions will not be displayed on the screen. These functions like T.AL, ODO, mBAR, DST/D are displayed only when you stop riding.
8. About Altitude Calibration: Tip for Quick Altitude Calibration 1. Press both A and B buttons for 1 second, and the current altitude value will return to zero. 2. Press the A button to set the value of a digit, and press the B button to move to the next digit. 3. Attention: Calibrate the current altitude only when there're no speed signals.
9. Temperature Display The following operation is for Echo-a2 only: 10. Bike 1 /Bike 2 Selection Bike 1 and Bike 2 have their separate data in the computer.
11. Data Reset 1. Press and hold the A button for 3 seconds to reset data of DST, RTM, MAX, AVG, ALT,MAX-ALT, MAX-RPM, AVG-RPM (for Echo-a2 only) 2. The following data are stored in memory and cannot be reset: Unit, Cmm1 (Circumference 1), Cmm2, ODO 1, ODO 2, T.RT1, T.RT2, T.AL1, T.AL2. 3. Reset data for Bike 1 and data for Bike 2 respectively.
12. EL Backlight 13. Sleep Mode Press the A or B button to wake it up.
Functions The display of the computer can be divided into three sections – upper, middle, and lower display. In General Mode, the LCD display of your computer is as below: The current altitude is always shown on the upper display, and it's easy to calibrate it when necessary. For Echo-a1 users, current speed and temperature are always shown on the middle display. For Echo-a2 users, current speed and current RPM are always shown on the middle display.
For Bike 2, when you do not ride the bike for more than 2 seconds, the speed data will be reset to zero. MAX Max. Speed 1. With this function, the computer will record the maximum speed you reach during riding. 2. Whenever you reset the computer or change the battery, the max. speed record will be cleared. AVG Average Speed 1. With this function, the computer will display your average speed during riding. 2.
wheel signals. If you are riding your Bike 2, the computer will count the riding time for 2 more seconds for the same reason. Regarding the riding time it over counts, the computer will automatically deduct it and show the correct riding time. RPM Current Cadence (for Echo-a2 only) 1. RPM (Revolutions Per Minute) is a measure of rotational speed. It's updated every second. 2. The current RPM (cadence) is always shown on the middle display. 3.
ALT Accumulated Altitude Gains (During a Trip) 1. With this function, it displays the accumulated altitude gains during a trip. 2. When you ride over uphill paths, the altimeter will accumulate the altitude gains. However, when you ride over downhill paths, the computer will not deduct the altitude loss. The altimeter always accumulates your altitude gains only. 3. Attention: The altitude gains are accumulated during riding only. MAX. ALT Maximum Altitude (During a Trip) 1.
2. The altimeter converts the millibar value of atmospheric pressure into the current altitude. 3. Attention: There is a hole at the bottom of the main unit for measuring the air pressure. The hole for measurement should be always kept clean. Besides, do not poke anything into the hole to avoid damage. ODO Odometer 1. With this function, the computer accumulates the total distance of the bike you ride. 2. The odometer data cannot be cleared by the reset operation.
T.AL Total Accumulated Altitude Gains 1. It displays the total accumulated altitude gains during all previous trips . 2. The accumulated altitude gains cannot be cleared by the reset operation. T.AL (1)+(2) Total Accumulated Altitude Gains (Bike 1 + Bike 2) 1. It displays the total altitude gains accumulated during all previous trips of the two bikes you ride. 2. The sum of T.AL 1 and T.AL 2 equals T.AL (1) (2). (i.e. total accumulated altitude gains of bikes 1 and 2) 3.
Low Battery Indicator 1. When the low-battery indicator appears on the display, it's time to get a new battery. 2. Replace the battery with a new one A.S.A.P. when the symbol blinks on the display. Otherwise, the new data of some functions will not be stored into the computer. 3. If you do not change the battery in a few hours, the computer may still work for a few days. The data will be displayed as usual, but the new data will not be stored before the battery is changed. 4.
