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. Since the weather is changing, the

altitude (converted from the air pressure measurement) for the same

location may be variable at different times. However, if there's no

rapid weather change, the altitude differences caused by the

weather are limited and can be generally accepted. Do not use this

computer as a specialized device for altitude measurement.

The altitude value shown in each Echo-a1 or Echo-a2 computer is

pre-calibrated by the precise instrument at the factory before

shipment. However, to get accurate basis altitude, we suggest that

you calibrate the current altitude data before each ride. And the

calibration of altitude for your Echo-a series is quite easy. (Refer to

the content about button operation.) You may obtain the altitude

information from topographic maps or the Internet. If you are

unaware of your basis altitude or do not care about the home altitude,

you may reset the altitude to zero before riding. In this way, the

cyclist can still enjoy the fun of learning the accumulated altitude

gains during the trip. The altitude data can be your reference for

riding over the same hills or mountains next time.

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 first time when you use the computer

2-2. When the display becomes irregular due to improper use

2-3. Whenever you change the battery

2. Basic Display Modes:

After initiating the computer, selecting units, you should enter

Data Setting Mode to set some basic data like wheel

circumference and clock time etc. Then go to General Mode for

normal operation.

Before riding, you should enter Altitude Calibration Mode to

calibrate the current altitude value.

The following is the General Mode Display during riding for

reference:

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.

2. Button for entering or quitting Data Setting Mode: C

3. Button for changing the value of a flickering digit: A

4. Button for switching to the next digit or setting: B

Button A:

1. Press the A button to change the value of a

flickering digit in a loop.

2. If you keep pushing the A button, the digit value will

automatically increase.

3.Release the A button when the required value of a

digit is displayed.

Button B:

1. Press the B button to move to the next digit in a

loop.

2. Push the B button for 1 second to move to the next

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. In General Mode:

Tips:

1. The buttons you'll use in General Mode: A, B, C, D

2. Button for changing the function display: A

3. Button for resetting the trip data: A (3's)

4. Button for entering Data Setting Mode: C

5. Buttons for entering Altitude Calibration Mode: A+B (3's)

Button A:

1. Press the A button to move to the next function

display.

2. Press the A button for 3 seconds, and you will

reset the following data:

AVG SPD, MAX SPD, DST, RTM, ALT, MAX ALT,

AVG RPM, MAX RPM.

(AVG RPM and MAX RPM are for Echo-a2 only.)

Button B:

1. Press the B button to turn on the EL backlight.

2. The following function is for Echo-a2 only:

Press the B button for 1 second, and the

temperature will be displayed.

Button C:

Press the C button, and you'll enter Data Setting

Mode.

Buttons A+B:

Push both buttons for 3 seconds, and you'll enter

Altitude Calibration Mode.

Button D:

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. In this mode, press A and B buttons at the same

time briefly, and the current altitude value will

return to zero. It's convenient for quick setting.

3. Push A and B buttons for 3 seconds to quit this

mode and return to General Mode.

Button A:

1. Press the A button to change the plus sign to

minus, or change the minus sign to plus.

2. Press the A button to change the value of a

flickering digit during setting.

Button B:

Press the B button to move to the next digit in a

loop during setting.

About Altitude Calibration:

1. If you are aware of your home altitude or basis altitude before riding, you can

directly adjust the current altitude data after you enter this mode.

2. If you do not know your basis altitude before riding or if you do not care

about the altitude of the starting point, you may return the current

altitude value to zero in the calibration mode by pressing both A and B

buttons at the same time briefly. In this way, the rider will still enjoy the

fun of learning the accumulated altitude gains during each ride.
