®

A10W cyclocomputer. With all the features that a professional rider

needs to keep track of a ride, the A10W is the perfect training tool for any cyclist. The added convenience of wireless

transmission makes installation simple.

LEFT KEY

Use this button to progress through the TRP, RID, AVS, STP and MAX display screens and to access and progress

through the set-up screens.

RIGHT KEY

Use this button to progress through the TCNT, CLK and ODO screens, start and stop the stopwatch and to adjust values

within the set-up screens.

WHEEL SIZE SETTING (WS1, WS2)

Wheel circumference is used to calculate speed and distance. Setting

range is 0000mm-3999mm (KMH) and 000.0"-157.4" (MPH). The A10W

includes two wheel size settings, WS1 and WS2, allowing you to use the

computer on two bikes with different wheel sizes (e.g. your road bike

and mountain bike).

SPEEDOMETER (SPD) (MPH or KMH)

Displays instantaneous speed, up to 120KMH (75MPH). Accurate to

whole mile or kilometer. Always displayed at the top of the screen.

SPEED COMPARISON (

)

Compares current speed to average speed. As you ride, a

(

▲

), (•) or (

▼

) will appear in the upper left corner of the display to

indicate whether your current speed is above (

▲

) equal to (•) or

below (

▼

) your average speed. This function is automatic, requires

no programming and cannot be disabled.

TRIP DISTANCE (TRP)

Displays distance traveled during current ride, up to 999.99 mi. or km.

AUTOMATIC RIDE TIMER (RID)

Auto start/stop timer records actual ride time up to 9:59:59.

Activated by front wheel movement.

AVERAGE SPEED (AVS)

Displays average speed. Calculated using true ride time

(RID) and trip distance (TRP).

STOPWATCH (STP)

Manual stopwatch allows you to time your entire ride or

portions of your ride, up to 9:59:59.

MAXIMUM SPEED (MAX)

Displays the fastest speed attained during a ride, up to 120KMH

(75mph).

SECOND TRIP COUNTER (TCNT)

Displays distance traveled with a quick reset option, which is particular-

ly useful when following route sheets with turn by turn instructions or

tracking point to point distances within a ride.

CLOCK (CLK)

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

ODOMETER (ODO)

Displays cumulative ride distance, up to 99,999 mi. or km.

AUTO SLEEP

To prolong battery life, the A10W will automatically enter "sleep" mode

after 5 minutes of non-use. The computer will automatically restart as soon as it receives input from the speed sensor,

or when any button is pressed. Note: To prolong battery life, we recommend removing the head unit from the handle-

bar bracket between rides.

SCROLL MODE

In the RID, TRP or AVS display screen, pressing the LEFT key for 1.5 seconds will activate the scroll function. The com-

puter will automatically scroll once through the RID, TRP and AVS screens, displaying each screen for 1.5 seconds.

The TRP, RID, AVS and MAX display screens are reset simul-

taneously. In any of these four display screens, pressing the

RIGHT key for 5 seconds will reset the data in all four screens

to zero.

The STP display screen is reset independently. In the STP dis-

play screen, pressing the RIGHT key for 5 seconds will reset

the stopwatch to zero.

The TCNT display screen is reset independently. In the TCNT

display screen, pressing the RIGHT key for 5 seconds will

reset the trip counter to zero.

To reset ALL display screens and ALL programmed settings (including CLK, ODO and wheel size settings), use a pencil

to depress the ‘AC’ button on the underside of the computer head. See Figure 1.

COMPUTER HEAD/RECEIVER

To prolong battery life, the A10W battery is

not installed at the factory. Before program-

ming or using the computer the battery

(included) must be installed. The Axiom

®

A10W uses a common 3V CR2032 button

cell battery. Replacement batteries are avail-

able at most camera and electronic shops.

Under normal usage a battery should last

approximately one year. Note: Most prob-

lems that occur with cyclocomputers are

caused by dead or weak batteries. If you are

having problems with your computer’s oper-

ation, check and replace the battery first.

STEP 1

Remove the battery cap from the bottom of the computer using a small coin. See Figure 2.

STEP 2

Install the battery in the battery compartment with the positive (+) side facing the battery

cap. Be careful when installing the battery not to damage the battery contact.

STEP 3

Reinstall the battery cap and tighten firmly, making sure that the rubber O-ring does not get

pinched or distorted, as this will compromise the unit’s watertight seal.

Note: During a battery change your computer will retain programmed values and odome-

ter mileage for approximately 30 seconds. If the battery is not replaced within 30 seconds,

all data will be cleared and default settings restored. Make a note of your current wheel

size settings and cumulative odometer mileage before replacing the battery so you can

reprogram these values if necessary once the new battery is installed. (see "Programming

Wheel Size" and "Setting the Odometer").

STEP 4

If for some reason the screen is blank or shows an irregular display after a battery change, press the AC button on the

underside of the computer head (see "Reset Display Screens").

SENSOR/TRANSMITTER

The A10W sensor/transmitter comes from the factory with the A23 LR23 12V battery already installed.

STEP 1

To replace the battery, remove the battery cap from the top of the transmitter using a small coin. Remove the old bat-

tery and dispose of properly.

STEP 2

Install a new battery with the positive (+) end facing the cap. Reinstall the battery cap and tighten firmly, making sure

that the rubber O-ring does not get pinched or distorted, as this will compromise the unit’s watertight seal. See Figure 3.

Now that you are familiar with the features of your Axiom

®

A10W cyclocomputer, you are ready to program the unit

specifically for your bike.

SELECTING MILES OR KILOMETERS

The Axiom

®

A10W is capable of displaying speed and distance information in

either miles or kilometers. You can switch between miles and kilometers at

any time by entering the programming mode and changing your selection.

STEP 1

With the computer in the TRP display screen, press and hold the

LEFT key for 5 seconds.

STEP 2

"KMH" or "MPH" will flash in the upper right corner of the screen. Press the

RIGHT key to select miles (MPH) or kilometers (KMH).

STEP 3

Press the LEFT key to set your choice and advance to the first wheel size (WS1) setting screen.

The Axiom

®

A10W uses wheel circumference (measured in millimeters or inches) to calculate speed and distance.

Note that while your computer can be programmed to +/-1mm (+/- 0.1") for total accuracy, discrepancies of as much as

50mm (2") will not have a significant effect on the accuracy of the unit for most normal rides. The following 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.

WHEEL SIZE CALCULATION

If your specific tire size is not listed in the chart, follow these steps to measure wheel circumference.

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 floor to indicate the valve location. See Figure 4.

STEP 2

Roll the bicycle forward in a straight line for one complete wheel revolution, until the valve is again at the bottom.

Make a mark on the floor to indicate the valve location.

STEP 3

Measure the distance between the marks in millimeters or inches (1 inch = 25.4mm). This value is your wheel circum-

ference. Enter this value in the computer (see "Programming Wheel Size"). Note: If you set your computer to read in

kilometers, you must program the wheel size in millimeters. If you set your computer to read in miles, you must pro-

gram the wheel size in inches.

STEP 1

Once you select miles (MPH) or kilometers (KMH) and press the LEFT key (see STEP 3 of "Programming the

Computer"), the computer will automatically advance to the first wheel size (WS1) programming screen. Note: If you

set your computer to read in kilometers, you must program the wheel size in millimeters. If you set your computer to

read in miles, you must program the wheel size in inches.

STEP 2

The WS1 default settings are 2155 for KMH and 84.8 for MPH. The digit at

the right of the screen will flash. Use the RIGHT key to adjust the value.

STEP 3

Press the LEFT key 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. Press the LEFT key again to set the WS1 value in memory and

advance to the second wheel size (WS2) programming screen. If you do

not wish to program a value for the second wheel size setting, press and

hold the LEFT key for 5 seconds to return to the TRP display screen.

STEP 5

The WS2 default settings are 2000 for KMH and 78.7 for MPH. Use the RIGHT and LEFT keys to adjust the wheel size

value as described above.

STEP 6

Once all the digits have been set to the appropriate value, press the LEFT key to set the WS2 value in memory, and

return to the TRP display screen.

To select WS1 or WS2 before a ride, press and hold the LEFT key for 5 seconds in any of the RID, AVS, STP or MAX

display screens, but not the TRP screen. Don’t forget to select the correct wheel size when switching the computer

between bikes.

The Axiom

®

A10W is equipped with a digital clock that displays time of day in a 12 hour or 24 hour format.

STEP 1

With the computer in the CLK display screen, press and hold the LEFT key for 5 seconds.

STEP 2

"24:" or "12:" will flash in the lower line of the display. Press the RIGHT key to select the 12 hour or 24 hour mode. Press

the LEFT key to set your choice and advance to the hours setting.

STEP 3

Press the RIGHT key to advance the hours. (Hold this key to quickly advance the hours.) Press the LEFT key to set the

value and advance to the minutes setting.

STEP 4

Press the RIGHT key to advance the minutes. (Hold this key to quickly advance the minutes.) Press and hold the LEFT

key for 5 seconds to set the value and return to the CLK display screen.

The odometer can be programmed so that cumulative mileage can be

restored after a battery change or transferred from another computer.

STEP 1

With the computer in the ODO display screen, press and hold the LEFT key

for 5 seconds.

STEP 2

The digit at the right of the screen will flash. Use the RIGHT key to adjust the

value.

Press the LEFT key to set your choice and advance to the next flashing digit.

STEP 3

Repeat this sequence until all digits have been set to the appropriate value.

STEP 4

Press and hold the LEFT key for 5 seconds to set the odometer value and return to the ODO display screen.

The second trip distance counter can be programmed at any time—a useful feature while following a route

sheet with turn by turn instructions.

STEP 1

With the computer in the TCNT display screen, press and hold the LEFT key for 3 seconds.

STEP 2

The digit at the right of the screen will flash. Use the RIGHT key to adjust the value. Press the LEFT key to set

your choice and advance to the next flashing digit.

STEP 3

Repeat this sequence until all digits have been set to the appropriate value.

STEP 4

Press and hold the LEFT key for 3 seconds to set the value in memory and return to the TCNT display screen.

Since the A10W is wireless, installation is simple and straight forward. Begin by attaching the computer mounting

bracket o the handlebars.

BRACKET INSTALLATION

STEP 1

Determine whether you will mount the computer head to the left or right of your handlebar stem. The speed

sensor/transmitter should then be attached to the fork on the same side of the bike as the computer head.

STEP 2

Remove the backing from the adhesive pad on the underside of the bracket. Use the included O-ring to attach the

bracket to the handlebar as shown in Figures 5A & 5B. Use the included shim to accommodate smaller diameter han-

dlebars, sticking the adhesive side of the shim to the underside of the bracket.

HEAD UNIT INSTALLATION

The Twist-Click bracket design securely locks the A10W computer head into the bracket. Set the computer head into

the bracket, and twist the head clockwise until you hear an audible ‘CLICK’, indicating that the unit is locked firmly in

place. See Figure 6. To remove the head unit, twist the head counterclockwise and then lift it out of the bracket.

WHEEL MAGNET AND SENSOR INSTALLATION

STEP 1

Using the included rubber shim and zip-ties, loosely mount the sensor (so that you can slide it around) to the fork blade

so that it’s on the same side of the bike as the handlebar bracket. The A10W transmission range is 24" (60cm). The sen-

sor/transmitter must be mounted within 24" of the receiver (computer head) in order for the receiver to pick up the sig-

nal. The sensor/transmitter battery cap should face up. See Figure 7. Note: 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 3

Attach the wheel magnet loosely to one of the spokes on the same side of the wheel and directly opposite the

sensor/transmitter. Adjust the position of the magnet and sensor by sliding both pieces up or down to achieve 1-3mm

clearance between the two. Note: 1mm is about the thickness of a penny. If the magnet and sensor are not close

enough, the computer will not pick up a reading or readings will be inconsistent and erratic. Most problems that occur

when installing a new computer are related to magnet and sensor alignment and spacing. See Figure 8.

STEP 4

Once the transmitter and wheel magnet are aligned properly, securely tighten both in place.

TEST OF INSTALLATION

Once the installation procedure is complete, test the unit to make sure everything is adjusted and working properly.

STEP 1

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 mag-

net and sensor is 3mm or less. Adjust as necessary and re-test. Note: 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 (such as heart rate monitors). If you experience

unusually high speed readings, check your surroundings for possible sources of electromagnetic signals and

move away from the source.
