WHEEL CIRCUMFERENCE
1. Roll the wheel until the valve stem at its lowest point close to the ground, then mark this first
point on the ground.
(Fig. a)
2. Get on the bike and have a helper push you until the valve stem returns to its lowest point.
Mark the second point on the ground. (Sitting on the bike achieves a more accurate reading
since the weight of the rider slightly changes the wheel circumference).
3. Measure the distance between the marks in milimeters. Enter this value to set the wheel
circumference.
Option: Get a suitable circumference value from the table.
(Fig. b)
4. Adjust the wheel circumference as the data setting process.
5. Unit will change to the normal operation after this circumference setting.

BATTERY CHANGE (Fig. c)
1. When the brightness of the LCD display is dim, it means that the battery is nearly exhausted.
2. Replace a new LR44 (Cross reference type A76, AG13 or V13GA) battery in the compartment on the back
of the computer with the positive (+) pole toward the battery cap.
PROBLEM
CHECK ITEM
REMEDY
1. Replace the battery.
2. Be sure that the positive pole of the
battery is facing the battery cap.
1. Refer to the adjusting procedure
and complete the adjustment.
2. Wipe contacts clean.
3. Refer to Installarions (Fig.B3~B4) and
readjust data correctly.
4. Repair or replace wire.
5. Refer to "CALIBRATION" and enter
correct value.
Refer to the "MAIN UNIT SETUP" and initiate
the computer again.
Place main unit in the shade to return to
normal state.No adverse effect on data.
Unit will return to normal state when the
temperature rises.
1. Is the battery dead?
2. Is there incorrect battery installation?
1. Is it at the recalibrating or clock setting
screen?
2. Are the contacts between the
main unit and the bracket poor?
3. Are the relative positions and gap
of sensor and magnet correct?
4. Is the wire broken?
5. Is the circumference correct?
Did you leave main unit under direct sunlight
when not riding the bike for a long time?
Is the temperature below 0°C (32°F)?

2. Don’t leave the main unit exposed to direct sunlight when not riding the bike.
3. Don’t disassemble the main unit or it’s accessories.
4.
Check relative position and gap of sensor and magnet periodically.
5. Clean the contacts of the bracket and the bottom of the main unit periodically.
6. Don’t use thinner, alcohol or benzine to clean the main unit or its accessories when they become dirty.
7. Remember to pay attention to the road while riding.
FUNCTIONS
:
Current Speed
0.0–199.9Km/h (120.0 Mile/h), 0.1Km/h (Mile/h), +/- 1%
The current speed is always displayed on the upper set when riding. It displays current speed up
to 199.9 Km/h or 120.0 Mile/h (for wheel diameters over 24 inches).
ODO1, ODO2:
Bike1 odometer, Bike2 odometer
0.0–99999.9 Km (Miles), 0.1Km (Mile), +/- 0.1%
1. The odometer cumulates the total distance as long as the bike is running.
2. This computer design has 2 wheel circumference memories to calculate data for 2 bikes. The
odometer is separated for each bike.
3. It displays one ODO data only when the bike is selected in the current status.
T-TM:
Total Riding Time
0H00M-9999H59M, 1 Minute, +/- 0.003%
The T-TM accumulates total riding time while ri
ding t
he bike1 and bike2.
T-ODO:
Total Odometer
0.0–99999.9 Km (Miles), 0.1Km (Mile), +/- 0.1%
The T-ODO is the sum of the ODO1 plus ODO2.
:
12HR or 24HR Clock 1H00M00S–12H59M59S or 0H00M00S–23H59M59S, 1 Second, +/- 0.003%
It can display the current time either in 12HR or 24HR clock.
AVG:
Average Speed
0.0–199.9 Km/h (120.0 Mile/h), 0.1Km/h (Mile/h), +/- 0.1%
1. It is calculated from the DST divided by the TM. The average data counted is from the last
RESET to current point.
2. It will display "0.0" when TM is less than 4 seconds.
3. It is updated about one second when TM is over 4 seconds.
4. It displays an "Err" symbol when either the TM is over 100 hours or the DST is over 1,000 km
(or miles). Reset the unit in order to restart.
DST:
Trip Distance
0.00–999.99 Km (Miles), 0.01Km (Mile), +/- 0.01%
The DST function accumulates the distance data from the last RESET operation as long as the
bike is being ridden.
TM:
Riding Time
0M00.0S-59M59.9S, 0.1 Second, 1H00M00S-99H59M59S, 1 Second, +/- 0.003%
1. The TM totals the riding time from the last RESET operation.
2. It will automatically begin counting upon
ding, and continue to count 2 seconds to confirm that no more wheel sensing signal is sent
when riding is stopped.
But this computer revises back the overcounted 4 seconds automatically.
3. It displays in 0.1 second increments when TM is less than 1 hour and changes to 1 second
increments after 1 hour. It will restart from zero after 100 hours.
MAX:
Maximum Speed
0.0–199.9Km/h (120.0 Mile/h), 0.1Km/h (Mile/h), +/- 1%
It shows the highest speed from the last RESET operation
DST/D:
Distance Today
0.00–999.99Km (Miles), 0.01Km (Mile), +/- 0.01%
The DST/D function accumulates the distance data for one day rode. The data will be cleared at
AM 12:00:00 (0:00:00) automatically.
/ :
Speed Pacer
It flashes the " " speed pacer arrow while the current speed is higher than the average speed
and flashes the " " conversely as long as the bike is being ridden.
