Handleiding Ascent IO Fietscomputer

Handleiding

INTRODUCTION

Thank you for purchasing an Ascent™ cycle

computer. With all the features that a professional

rider needs to keep track of a ride, the Ascent

IO is the perfect accessory for any cyclist. The

convenience of coded wireless transmission

makes installation simple and virtually eliminates

interference issues.

BATTERY INSTALLATION

To help you get started quickly, the computer and

transmitter batteries have been installed at the

factory. Under normal use the batteries should last

one to two years. The Ascent IO uses a 3V CR2032

button cell battery (available at most drug stores

or electronic shops) in both the computer and the

transmitter.

NOTE: Most problems that occur with cycle

computers are caused by weak or dead batteries.

Should you need to replace the batteries, follow the

steps below.

COMPUTER HEAD

NOTE: During a battery change, all data will be

cleared from memory. Make a note of your current

wheel size settings and cumulative odometer

mileage before replacing the battery so you

can reprogram these values once the battery is

replaced.

STEP 1: Remove the battery cover from the

underside of the computer using a coin. See

Figure 1. Remove the old battery and dispose of it

properly.

STEP 2: Install a fresh battery with the positive (+)

side facing the battery cover.

STEP 3: Install the battery cover securely, making

sure the rubber O-ring seal around the battery

compartment is still in place and seated properly.

TRANSMITTER

STEP 1: Remove the battery cover from the back of

the transmitter using a coin. See Figure 1. Remove

the old battery and dispose of it properly.

STEP 2: Install a fresh battery with the positive (+)

side facing the battery cover.

STEP 3: Install the battery cover securely, making

sure that the rubber O-ring seal around the battery

compartment is still in place and seated properly.

COMPUTER FUNCTIONS

CLOCK (CLK)

Displays time of day in a 12 hour or 24 hour

format.

AUTOMATIC RIDE TIMER (TM)

Auto start/stop timer is activated by front wheel

movement and records actual ride time up to

29:59:59.

CURRENT SPEED (M/H or KM/H)

Displays current speed, up to 62.4 M/H (99.9 KM/

H). Accurate to 0.1 M/H or KM/H. Always displayed

at the top of the screen.

AVERAGE SPEED (AVS)

Calculates average speed based on ride time (TM)

& trip distance (DST).

MAXIMUM SPEED (MXS)

Displays highest speed attained during a ride (or

since last reset), up to 62.4 M/H (99.9 KM/H).

SPEED COMPARISON INDICATOR ( or )

Compares current speed to average speed. As

you ride, a ( ) or ( ) will appear next to the current

speed display to indicate whether your current

speed is above ( ) or below ( ) your average speed.

This function is automatic, requires no program-

ming and cannot be disabled.

TRIP DISTANCE (DST)

Displays distance traveled during current ride

(or since last reset), up to 624.99 miles (999.99

kilometers).

ODOMETER (ODO 1)

Displays cumulative ride distance, up to 62,499

miles (99,999 kilometers) for wheel size .

ODOMETER (ODO 2)

Displays cumulative ride distance, up to 62,499

miles (99,999 kilometers) for wheel size .

TOTAL ODOMETER (ODO)

Displays total cumulative ride distance for both

wheel sizes combined, up to 62,499 miles (99,999

kilometers).

DUAL WHEEL SIZE SETTINGS or

Wheel circumference is used to calculate speed

and distance. The Ascent IO computer includes two

wheel size settings ( and ), to keep track of

ride data on two bikes with different wheel sizes

(e.g. your road bike and mountain bike).

TEMPERATURE

Displays air temperature in °F or °C, from 32°F to

122°F.

AUTO SLEEP

To prolong battery life, the Ascent IO automatically

enters “sleep” mode after 30 minutes of inactivity.

In sleep mode, only the time of day will be dis-

played. To activate the computer when it’s in sleep

mode, simply press the MODE button.

DETERMINE WHEEL SIZE

The Ascent IO uses wheel circumference

(measured in millimeters) to calculate speed and

distance. Before programming the computer,

calculate wheel circumference using one of the

three methods below.

1. Select size from chart (least accurate): Use the

chart below to find the circumference for your

tire size. The chart lists the programming sizes

for some of the most popular tire sizes currently

in use. These numbers are estimations which

may not precisely match the circumference of

your wheel, due to variations in tire size between

brands and models.

2. Measure wheel diameter (more accurate):

Measure your wheel diameter (including wheel

and tire) in millimeters (1 inch = 25.4mm) and

multiply by 3.1416. This value is your wheel

circumference.

3. Perform roll-out test (most accurate):

See Figure 2.

STEP 1: Stand your bicycle upright. With your tires

inflated to their normal riding pressure, rotate the

front wheel so the valve stem is located at the 6

o’clock position. Make a mark on the ground to

indicate the valve location.

STEP 2: Roll the bicycle forward in a straight line

for one complete wheel revolution, until the valve

stem is again at the bottom (ideally, you should

be on the bike). Make a mark on the ground to

indicate the valve location.

STEP 3: Measure the distance between the marks

in millimeters (1 inch = 25.4mm). This value is

your wheel circumference.

PROGRAM THE COMPUTER

Before using your Ascent IO, you must set the

clock, select a speed scale (miles or kilometers),

program wheel size, set the odometers (if desired),

select a temperature scale (°F or °C) and program

gender and weight.

SET THE CLOCK

The Ascent IO is equipped with a digital clock

that displays time of day in a 12 hour or 24 hour

format.

STEP 1: Press the MODE button to advance to

the Clock display screen (CLK). Then press and

hold the red SET button on the underside of the

computer to enter set-up mode. See Figure 3.

STEP 2: “12” or “24” will flash at the top of the

screen. Press the SET button to select 12 hour or

24 hour mode. Press the MODE button to confirm

your selection and advance to the hours setting.

STEP 3: The hours will flash. Press the SET button

(or press and hold) to advance the hours. If you

selected 12 hour mode, “PM” will appear for hours

between noon and midnight. Press the MODE

button to advance to the minutes setting.

STEP 4: The minutes will flash. Press the SET

button (or press and hold) to advance the minutes.

Press the MODE button to advance to the seconds

setting.

STEP 5: The seconds will flash. Press the SET

button to reset the seconds to “00”. Press and hold

the MODE button to exit set-up mode.

SELECT SPEED SCALE

The Ascent IO is capable of displaying speed and

distance information in miles or kilometers.

STEP 1: Press the MODE button to advance to

the Odometer display screen (ODO). Then press

and hold the SET button on the underside of the

computer to enter set-up mode.

STEP 2: “M/H” or “KM/H” will flash in the display

screen. Press the SET button to select miles (M/H)

or kilometers (KM/H).

STEP 3: Press the MODE button to confirm your

selection and advance to the wheel size

programming screen.

PROGRAM WHEEL SIZE AND ODOMETER (ODO1)

STEP 1: After the speed scale has been selected

(see above), the computer will automatically

advance to the wheel size selection screen. “ ” or

“ ” will flash at the top of the screen.

STEP 2: Press the SET button to select wheel size

. Press the MODE button to confirm your

selection and advance to the wheel size setting.

STEP 3: The left-most digit will flash. Press the SET

button to adjust the value according to the wheel

circumference determined above (see “Determine

Wheel Size”). Then press the MODE button to

advance to the next flashing digit.

STEP 4: Repeat this sequence until the correct

wheel size has been entered. Then press the MODE

button to advance to the odometer setting (ODO1)

for wheel size . (If you don’t wish to program

the odometer, press the MODE button 5 times to

advance to the temperature scale selection screen,

or press and hold the MODE button to exit set-up.)

STEP 5: The left-most digit will flash. Press the

SET button to adjust the value. Then press the

MODE button to advance to the next flashing digit.

STEP 6: Repeat this sequence until the odometer

value for wheel size has been set. Then press

the MODE button to advance to the temperature

scale selection screen, or press and hold the MODE

button to exit set-up.

SELECT TEMPERATURE SCALE

STEP 1: After the odometer has been set (see

above), the computer will automatically advance to

the temperature scale selection screen. “°F” or “°C”

will flash at the bottom of the screen.

STEP 2: Press the SET button to select Fahrenheit
