Delta HR

Wireless Cycle

Computer with

Heart Rate

INTRODUCTION

Thank you for your purchase of an Ascent computer! The

Ascent Delta hr combines all the features of an advanced cycle

computer with ECG accurate heart rate technology to create

the ultimate training tool. The added convenience of wireless

transmission makes installation simple.

COMPUTER FUNCTIONS

Current Speed

Displays current speed up to 62mph (99.9kmh). Accurate to

0.1mph or kmh. Current speed is always displayed in the top

right corner of the screen.

Current Heart Rate

Provided the chest transmitter is being used, current heart

rate is displayed in the top left corner of all display screens.

Modes

Press the MODE button to scroll through the Delta hr display

screens in the following order:

Clock (CLOCK)

Displays time of day in a 12 hour or 24 hour format.

Auto Ride Timer (AUTOTIME)

Auto start/stop timer is activated by front wheel movement

and records ride time up to 9:59:59.

Maximum Speed (MAXSPEED)

Displays maximum speed attained during a ride, up to 62mph

(99.9kmh).

Average Speed (AVGSPEED)

Displays average speed up to 62mph (99.9kmh). Calculated

using ride time and trip distance. Note, if either ride time or

trip distance reach their maximum value (9:59:59, or 600 mi.)

average speed can no longer be calculated correctly. “Err”

will appear in the display screen until the ride time and trip

distance values have been reset.

Trip Distance (TRIP)

Displays distance traveled during current ride, up to 600 mi.

(999.99 km).

Total Odometer (TOTALODO)

Displays cumulative ride distance, up to 6200 mi. (9,999.9

km).

Maximum Heart Rate (MAXPULSE)

Displays maximum heart rate attained since last reset. From

30bpm—240bpm.

Average Heart Rate (AVGPULSE)

Displays average heart rate attained since last reset. From

30bpm—240bpm.

Calorie Counter (KCAL)

Displays calories burned since last reset, up to 9999 Kcal.

Scan

Allows hands free viewing of display screens. When activated,

the scan feature scrolls through all nine display screens on a

continuous loop, displaying the screens for five seconds each.

Additional Features:

Dual Wheel Settings

Two wheel size settings allow you to switch the computer

between two bikes with different wheel sizes (e.g. your road

bike and mountain bike), and keep track of your combined ride

time and distance on both bikes. To select the desired wheel

setting (“I” or “II”), press the blue button on the underside of

the computer head.

Programmable Heart Rate Target Zone

Allows you to program upper and lower heart rate target zone

limits to ensure the most efficient workout based on your

specific fitness goals.

Out of Zone Alarm

Visual and selectable audible alarm indicates when your heart

rate rises above your target zone upper limit or falls below

your target zone lower limit.

Low Battery Indicator

Indicates when batteries should be replaced.

PROGRAMMING THE COMPUTER

SETTING THE CALORIE COUNTER

The Delta hr uses weight and gender to calculate calories

burned. In order for the calorie counter to provide an accurate

measurement, you must enter your weight and gender.

STEP 1: Press the MODE button to advance to the Calorie

(KCAL) display screen. Press and hold the SET button for 2

seconds to enter the personal settings screen.

STEP 2: Press the SET button to select gender, then press the

MODE button to advance to the weight scale selection screen.

STEP 3: Press the SET button to select the desired weight

scale (Kg or Lb). Then press the MODE button to advance to

the weight input screen.

STEP 4: Press the SET button (or press and hold) to adjust the

weight value. Press and hold the MODE button to set the value

and exit the set-up mode.

SETTING THE CLOCK

The Delta hr 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

(CLOCK) display screen. Press and hold the SET button for 2

seconds to enter the clock setting screen.

STEP 2: “12H” or “24H” will flash in the upper row of the

display. Press the SET button to select 12 hour or 24 hour

mode. Press the MODE button to set your choice and advance

to the hours setting.

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

and hold) to advance the hours. Press the MODE button to set

the value and advance to the minutes setting.

STEP 4: Press the SET button (or press and hold) to advance

the minutes. Press the MODE button to set the value and

advance to the seconds setting.

STEP 5: Press the SET button to reset the seconds to “00”.

STEP 6: Press and hold the MODE button to exit the clock set-

up screen and return to the Clock display screen.

DETERMINING WHEEL SIZE

The Delta hr uses wheel circumference to calculate speed

and distance. There are three methods for determining wheel

circumference:

1. Select size from chart below (least accurate)

2. Measure wheel diameter (more accurate)

3. Perform roll-out test (most accurate)

1. Chart: Use the chart to find the circumference for your tire

size, and enter this value in the computer (see “Programming

Wheel Size”). The chart lists circumferences for some of

the most popular tire sizes currently in use. These numbers

are only estimates which may not precisely match the

circumference of your wheel, due to variations in tire size

between brands and models.

2. Measure: Measure your wheel diameter (including wheel

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

3.1416. Enter this value in the computer (see “Programming

Wheel Size”).

3. Roll-out Test: See Figure 1.

STEP 1: Stand your bicycle upright. With your tire inflated to

its proper pressure, rotate your front wheel so that the valve is

located at the bottom (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 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. Enter this value in the computer (see

“Programming Wheel Size”)

PROGRAMMING WHEEL SIZE & SELECTING

MILES OR KILOMETERS

After determining wheel size by one of the three methods

above, enter the value in the computer.

STEP 1: Press the MODE button to advance to the Odometer

(TOTALODO) display screen. Press and hold the SET button

for 2 seconds to enter the wheel size setting screen.

STEP 2: “KM/H” or “M/H” will flash. Press the SET button to

select the desired speed scale (mph or kmh) and then press

the MODE button to set your choice and advance to the wheel

size setting.

STEP 3: The digit on the left side of the screen will flash. Press

the SET button to adjust the value. Press the MODE button to

set the value and advance to the next flashing digit.

STEP 4: Repeat this sequence until all digits have been set to

the appropriate value.

STEP 5: Press and hold the MODE button to set the wheel size

in memory and return to the Odometer display screen.

STEP 6: To program a second wheel size (if you plan to use

the Delta hr on two bikes with different wheel sizes), depress

the blue button on the back of the computer to activate the

second wheel size. Then follow steps 1 through 5 above, to

program the wheel size.

INSTALLATION

Wireless transmission makes installation simple. Begin by

attaching the computer bracket to the handlebar.

STEP 1: Use the included zip-ties and shim pad (if necessary)

to attach the bracket to the handlebar as shown in Figure 2.

Tighten the zip-ties securely and trim off any excess length.

STEP 2: Attach the

computer head to the

bracket. Press the

computer head into

the bracket and rotate

it clockwise to lock in

place. See Figure 3. You

should hear a “CLICK”

when the computer is

locked in place.

STEP 3: Using the included zip-ties, loosely mount the sensor (so

that you can slide it around) to the fork blade on the same side

of the bike as the handlebar

bracket. See Figure 4. The

Delta hr transmission range

is 24” (60cm). The sensor

must be mounted within 24” of

the computer in order for the

computer to receive the signal.

We recommend mounting the

sensor to the front (leading)

edge of the fork blade to avoid

problems should the sensor

ever come into contact with

the spokes.
