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.

STEP 4: Attach the wheel magnet loosely to one of the spokes
on the same side of the wheel as the sensor. Adjust the
position of the magnet and sensor by sliding both pieces up
or down to achieve 1-5mm of clearance between the two.
See Figure 5. If the magnet and sensor are not close enough,
the computer will not pick up a reading or the reading will
be inconsistent and erratic. Most problems that occur when
installing a new computer are related to magnet and sensor
alignment and spacing.
STEP 5: Once the installation procedure is complete, test the
unit to make sure everything is adjusted and working properly.
Pick up the front end of the bicycle and spin the front wheel.
The computer should register a speed reading within 1-2
seconds. If not, check the alignment of the wheel magnet and
sensor, and make sure that the space between the magnet and
sensor is 5mm or less. Adjust as necessary and re-test.
USING THE
HEART RATE MONITOR
1. Position the chest transmitter below the breast/pectoral
muscles as shown in Figure 6. Adjust the tightness of the
transmitter strap to achieve a snug, comfortable fit.
2. Use your maximum heart rate (MHR) and fitness goals to
select a target zone. The formula commonly used to determine
maximum heart rate for most individuals is: MHR = 220 – Age.
Target Zones:
50% - 60% MHR: Exercise in this zone to warm up and
burn fat.
60% - 70% MHR: Exercise in this zone to develop basic
endurance and aerobic capacity and burn fat, or to recover
from a more strenuous workout.
70% - 80% MHR: Exercise in this zone to increase
aerobic capacity.
80% - 90% MHR: Exercise in this zone to increase
anaerobic threshold.
3. Target zone settings vary for every individual depending on
age, personal fitness goals, existing medical conditions (high
blood pressure, circulatory or respiratory problems, etc.) and
personal physicians’ recommendations.
SETTING TARGET ZONE LIMITS
If you wish to exercise within a particular target zone and
utilize the out of zone alarm to alert you when your heart
rate rises above or falls below that zone, you must first set
upper and lower target zone limits. See “Using the Heart
Rate Monitor” for more information about determining an
appropriate target zone.
STEP 1: Press the MODE button to advance to the Maximum
Heart Rate (MAXPULSE) display screen. Press and hold the
SET button for 2 seconds to enter the target zone setting
screen.
STEP 2: The target zone upper limit will flash. Press the
SET button (or press and hold) to adjust the value (between
50bpm and 240bpm). Press the MODE button to set the value
and advance to the target zone lower limit.
STEP 3: Press the SET button (or press and hold) to adjust the
value (from the upper limit value minus 10bpm to 30bpm).
Then press and hold the MODE button to return to the Max
Heart Rate display screen.
STEP 4: To activate the audible out of zone alarm, press the
SET button in any display screen. To turn off the alarm, press
the SET button again. Please note, to prevent interference with
the wireless signal, the alarm will only sound when there is no
speed reading (no incoming data from the fork sensor).
OUT OF ZONE ALARM
The out of zone alarm indicates when your heart rate rises
above your target zone upper limit or falls below your target
zone lower limit.
An up arrow to the left of the heart rate value indicates your
current heart rate is above your preset target zone upper limit.
A down arrow indicates your current heart rate is below your
preset target zone lower limit.
An arrow pointing in both directions indicates your current
heart rate is within the upper and lower limits of your preset
target zone.
To activate the audible out of zone alarm, press the SET button
in any display screen. An alarm icon will appear in the display
to indicate the alarm is activated.
PLEASE NOTE: To avoid signal interference, the audible alarm
will sound only when the computer is not receiving data from
the fork sensor (when the front wheel is not moving).
RESET DISPLAY SCREENS
All display screens (except Odometer) are reset
simultaneously. Advance to the Auto Ride Timer (AUTOTIME)
display screen. Press and hold the SET button for three
seconds to reset all display screens to zero.
To reset all display screens including Odometer (TOTALODO)
AND reset all programmed settings (including gender, weight,
clock and wheel size) you must remove the battery from the
computer head. See “Battery Installation.”
MAINTENANCE
COMPUTER
If you notice a change in the display screen contrast, or if the
figures become faint, it may be time to replace the computer
battery. See “Battery Installation”. We recommend replacing
the computer head and fork sensor batteries at the same time.
CHEST TRANSMITTER
To extend the life of the chest transmitter, avoid scratching
the transmitter electrodes, or unnecessarily flexing or bending
the strap.
FORK SENSOR
Periodically check the alignment of the wheel magnet and fork
sensor and make sure that the space between the magnet and
sensor is 5mm or less. Remove any signs of rust or corrosion
from the magnet to ensure proper function.
CLEANING
The fork sensor, wheel magnet, handlebar bracket and chest
transmitter can all be cleaned with mild soap and water. Do
not use harsh abrasives or petroleum based cleaners to clean
any of the components.
BATTERY INSTALLATION
LOW BATTERY INDICATOR
When the computer head or fork sensor batteries are low, the
low battery icon will appear in the display screen. Make a note
of any data you wish to record (such as odometer reading or
wheel size settings) before replacing the batteries.
1. Chest Transmitter: Remove the screws from the battery
cover on the back side of the transmitter and remove the
cover. Remove the old battery and dispose of properly. Install
a new CR2032 battery with the positive (+) pole facing up.
Replace the cover and tighten the screws.
2. Computer Head: Insert a coin in the battery cover slot on
the back side of the computer head and twist counterclockwise
to remove. Remove the old battery and dispose of properly.
Install a new CR2032 battery with the positive (+) pole facing
up. Replace the cover and turn clockwise to tighten.
3. Fork Sensor: Insert a coin in the battery cover slot on the
back side of the fork sensor and twist counterclockwise to
remove. Remove the old battery and dispose of properly.
Install a new CR2032 battery with the positive (+) pole facing
up. Replace the cover and turn clockwise to tighten.
TROUBLESHOOTING
1. Absent or erratic heart rate
Make sure the chest transmitter strap is properly positioned
and sufficiently tight. Adjust the strap side to side or slightly
up or down to position it on the center of the chest with the
back side of the strap (the electrodes) flat against the skin.
Make sure there is sufficient moisture between the transmitter
electrodes and your skin. Re-moisten the transmitter
electrodes with water, saliva or a signal enhancing gel.
Accumulated dirt or residue may impair electrical contact
between the transmitter and your skin. Make sure the
transmitter electrodes are clean.
Make sure the transmitter battery is installed correctly and
fully charged. If in doubt, replace the battery with a fresh one.
2. Abnormally high or erratic heart rate
Electromagnetic interference may cause abnormally
high or erratic heart rate readings. Common sources of
electromagnetic interference include high voltage power
lines, motor driven equipment, computers, and other wireless
devices. Check your surroundings for possible sources of
electromagnetic signals and move away from the source.
3. Computer display is blank or very light
The computer battery may be low or installed incorrectly.
Make sure the battery is installed correctly, with the positive
(+) pole facing up, or replace the battery with a fresh one.
4. Computer display becomes dark or black
The ambient temperature may be too high. Allow the computer
to cool, and the display will return to normal.
5. Computer display appears to update slowly
The ambient temperature may be too low. When the
temperature rises, the display will return to normal. Note:
Even when the display is affected by cold, the computer will
continue to read and record data normally.
6. Absent or erratic speed reading
Check the alignment of the wheel magnet and sensor, and
make sure that the space between the magnet and sensor is
5mm or less. Adjust as necessary and re-test.
Wireless cyclocomputers are occasionally affected
by electromagnetic interference. Common sources of
electromagnetic signals include high voltage power lines,
motor driven equipment and other wireless devices. If you
experience unusually high speed readings, check your
surroundings for possible sources of electromagnetic signals
and move away from the source.
Make sure the computer head and fork sensor batteries are
installed correctly and fully charged. If in doubt, replace both
batteries with fresh ones.
