TROUBLESHOOTING
Q1. Display is black or very light:
The battery power may be low. Try a new battery and
make sure the battery is installed correctly.
Q2. Display becomes dark or black:
The unit is too hot. Place the unit in a shaded area and it
will return to normal.
Q3. The unit operates slowly or struggled:
The unit is too cold. Warm the unit and it will return
to normal.
Q4. Data in display varies enormously:
Check the surroundings for electro magnetic or high
energy interference and move away from the source of
interference.
Q5. Data in display shows slowly:
The unit may be aected by low temperature factor,
but it didn’t inuence the function reading. When the
temperature rises, the data reading will be back
to normal.
Q6. Current speed does not appear:
The distance and position between magnet and sensor
needs to be adjusted 2-3mm.

IMPORTANT HEALTH NOTICE!
Please read over the following information before using
the Cycle Computer.
Never use the cycle computer in combination with other
medical/implanted electronic equipment and device
(especially heart pacemakers, EKF equipment, TENS
equipment, cardiopulmonary machines or pacemakers.)
If you are severely ill or pregnant, please consult your
doctor before using cycle computer.
Keep this device away from children. It contains
batteries, which might be swallowed by children.
As with most electronic receiving devices, there can
sometimes be interference that causes inaccurate
display readouts. Avoid using your cycle computer
near common sources of interference. These include
high voltage power lines, air conditioning motor units,
uorescent lights, wristwatches, mobiles and computer.

KCAL MODE (CALORIE MODE)
It displays the accumulated calories consumed from the
beginning of the trip onwards.
Note: This accumulated calories display will return to 0
once it has been cleared under the TM MODE.
How to input gender, weight scale, and weight:
Press “SET” key for 3 seconds to go to gender setting.
Press “SET” key again to select MALE or FEMALE.
Press “MODE” key to go to kg or lb setting.
Press “SET” key to select kg or lb weight scale.
Then, press “MODE” key to go to weight input.
Press “SET” key to input the actual weight in
kg or lb. Press and hold “MODE” key for 3 seconds to
go back to KCAL Mode.
LOW BATTERY
A low battery warning will appear when the battery is
low and is in need of replacement.
BACK LIGHT (ABACUS 11 ONLY)
Press “SET” key at any time to activate the back light.
The back light will deactivate itself automatically after
4 seconds.
MAINTENANCE
If the display contrast changes and gures become
faint, it’s time to replace the battery. Consider changing
the computer sensor and transmitter batteries at the
same time.
Note: Do not expose the computer to extremely cold
or hot temperatures. Do not leave the unit in direct
sunlight for extended periods of the time.
Sensor:
Check the position of the magnet and sensor regularly.
Keep dry and free of dirt to ensure proper function.
Bracket/Magnet/Sensor band:
These items may be cleaned with water and mild soap.

TROUBLESHOOTING
Q1. Display is black or very light:
The battery power may be low. Try a new battery and
make sure the battery is installed correctly.
Q2. Display becomes dark or black:
The unit is too hot. Place the unit in a shaded area and it
will return to normal.
Q3. The unit operates slowly or struggled:
The unit is too cold. Warm the unit and it will return
to normal.
Q4. Data in display varies enormously:
Check the surroundings for electro magnetic or high
energy interference and move away from the source of
interference.
Q5. Data in display shows slowly:
The unit may be aected by low temperature factor,
but it didn’t inuence the function reading. When the
temperature rises, the data reading will be back
to normal.
Q6. Current speed does not appear:
The distance and position between magnet and sensor
needs to be adjusted 2-3mm.
