Congratulations on having chosen the cycle computer with altimeter functions from ECHOWELL. The easy operation of your new Echo-a3
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-a3 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-a3 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-a3, you are sure to get a lot of fun from riding with it.

riding.
2. The speed data are updated per second.
3. For Bike 1, when you do not ride the bike for more than 4 seconds,
the speed data will be reset to zero. For Bike 2, when you do not
ride the bike for more than 2 seconds, the speed data will be reset
to zero.
AVGSPD:AverageSpeedbike1/2
1. With this function, the computer will display your average speed
during riding.
2. Whenever you reset the computer or change the battery, the
average speed record will be cleared.
3. It'll display "0.0" if the riding time is below 6 seconds.
4. It's updated every second on condition that the riding time is over 6
seconds.
5. The computer will automatically reset the following data to zero
once the RIDETIME is over 100 hours or the DISTANCE is over
1000KM (or miles): RIDETIME (riding time), DISTANCE (trip
distance), AVG SPD (average speed.)
MAXSPD:MaximumSpeedbike1/2
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,
FUNCTION DESCRIPTION

EN 18
AVG BPM: Average Heart Rate bike1/2
Calculate the average heart rate during exercise: using this value we can
tell if the cardiopulmonary condition has improved for the same intensity of
exercise.
MAXBPM:MaximumHeartRatebike1/2
Monitors and records the maximum heart rate during exercise.
BPMT-Z:HeartRateTargetzone
With this function, the computer will display the target zone upper limi
t
(UP) and lower limit (LO).
IN T-Z: Time In Target Zone bike1/2
Calculate and record the exercise time within the target zone.
OVER T-Z: Time Over Target Zone bike1/2
Calculate and record the exercise time over the target zone.
CALORY:Caloryconsumptionbike1/2
1. Calculates the calories expended for the whole exercise process,
not only from exercise.
2. Males expend more calories than females at the same heart rate,
likewise, the female heart rate will be higher than male heart rate
doing the same amount of exercise.
3. Calories consumption will be affected by Heart rate, sexuality,
weight and type of exercise.
4. The unit for calories is Kcal.
5. The range is from 0 Kcal to 9999.99 Kcal.
6. Calory will be calculated when the heart rate is equal or over
90bpm.
--------------------------------------------------------------------------------------------
FUNCTION DESCRIPTION
the maximum speed record will be cleared.
DISTANCE:TripDistancebike1/2
1. DISTANCE refers to the accumulated distance during a trip.
2. Whenever you reset the computer or change the battery, the trip
distance record will be cleared.
RIDETIME:RidingTimebike1/2
1. RIDETIME refers to the accumulated riding time of a trip.
2. Whenever you reset the computer or change the battery, the trip
distance record will be cleared.
3. The computer automatically starts measuring the riding time
upon receipt of wheel signals. If you are riding your Bike 1,
whenever you stop, the computer will continue to count the riding
time for 4 more seconds to make sure there're no more 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.
DIST/DAY:Distanceperday
1. With the DIST/DAY function, the computer accumulates the
distance of your riding in one day.
2. The DIST/DAY data will be automatically cleared at 12:00:00 a.m.
(or 0:00:00) per day.
--------------------------------------------------------------------------------------------
PULSE:HeartRate
Display the current heart rate (BPM) on left side of middle display.

EN 19
ALTI:CurrentAltitude
1. The current altitude is always displayed on the upper display.
2. To get accurate basis altitude, the cyclist should calibrate the
altitude before each ride.
3. The measurement is based on the principle that atmospheric
pressure decreases as elevation increases.
4. The altitude is measured by means of the atmospheric pressure,
so it's weather- dependent.
5. You may obtain the altitude data from a topographic map or the
Internet.
6. The altitude of the altimeter is pre-calibrated by the precise
instrument
at the factory before shipment.
GAIN/LOSS: Trip altitude gain bike1/2 / Trip altitude loss bike1/2
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 accumulate the altitude loss. The altimeter always
accumulates your altitude gains only.
MAX ALTI/MIN ALTI: Maximun altitude bike1-2 /
Minimunaltitudebike1-2
1. With this function, the computer displays the maximum/minimum
altitude you reach during a trip.
2. The maximum/ minimum altitude record will be cleared after you
reset the computer or change the battery.
AVG ASC/AVG DES: Trip AVG altitude ascent bike1/2 /
TripAVGaltitudedescentbike1/2
1. With this function, the computer will display the average altitude
asscent/decent during riding.
2. Whenever you reset the computer or change the battery, the
average altitude asscent/decent record will be cleared.
MAX ASC/MAX DES: Trip MAX altitude ascent bike1-2 /
TripMAXaltitudedescentbike1-2
1. With this function, the computer will record your
maximum/minimum
asscent/decent during riding.
2. Whenever you reset the computer or change the battery, the
maximum/minimum asscent/decent record for a trip will be cleared.
MILLIBAR:Barometer
1. The altimeter is essentially a barometer, and millibar is a unit of
atmospheric pressure. (e.g. Standard atmospheric pressure at sea
level is about 1013 millibars.)
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.
