General Safety Information
WARNING TO PARENT / GUARDIAN
– To avoid serious injuries:
USE OF THIS PRODUCT IN ACCORDANCE WITH THESE SERVICE INSTRUCTIONS IS ESSENTIAL FOR YOUR
CHILD'S SAFETY. MAKE SURE YOU AND YOUR CHILD UNDERSTAND THESE SERVICE INSTRUCTIONS.
FAILURE TO FOLLOW THESE INSTRUCTIONS MAY RESULT IN SERIOUS PERSONAL INJURY.
• The analog compass (SM-TX32) may not always point to the right direction if it is installed to the bicycle in a
place where it is affected by metal such as brake cables.When checking the direction, stop the bicycle and
remove the compass from the bicycle. If you try to check the compass while the bicycle is moving, the bicycle
may become unstable because of being ridden with one hand, and this may cause a fall.
• Be careful not to pay excessive attention to the computer data while riding and do not change the display while
riding, otherwise you might have an accident.
• Keep used batteries out of the reach of children, and dispose of them in accordance with local waste regulations.
If batteries are swallowed by mistake, seek medical advice immediately.
• Read these Technical Service Instructions carefully, and keep them in a safe place for later reference.
Note
• If there is no signal from the sensor for 120 seconds, the power save function will operate and the LCD will turn
off.
• Never disassemble the cycle computer, as it cannot be reassembled.
• The cycle computer is fully waterproofed to withstand wet weather conditions; however, do not deliberately place it
into water.
• Avoid leaving the cycle computer exposed to extreme hot weather conditions as much as possible, because if the
cycle computer is left exposed to high temperatures or direct sunlight for long periods of time, the LCD may
become darkened. If this happens, place the cycle computer in the shade to let it cool down. It will then return to
normal.
• The ambient operating temperature range for the cycle computer is -10°C to 50°C. If the temperature is outside
this range, the movement of the data display may become sluggish or data may not be displayed.
• Handle the cycle computer carefully, and avoid subjecting it to any shocks.
• Do not use thinner or other solvents to clean parts such as the cycle computer and sensor, as such chemicals
may dissolve the part casings.
• To clean these parts, wipe them with cloth soaked in a weak mixture of neutral detergent and water.
• The battery which is included when the product is purchased is for the display computer, so the battery life may
be shorter than expected.
• Insert the battery so that the (+) side is visible. If the battery is inserted the other way around, the initial setting
data will be cleared.
• The analog compass (SM-TX32) may not always point to the right direction if it is in a place that is affected by
magnetism, even if it has been removed from the bicycle.The direction indicted by the compass should be used
only as a reference.
• If the analog compass becomes damaged or starts leaking, stop using it immediately.
• Use the analog compass in a place which is free from steel and sources of magnetic fields.
• This analog compass is classed as a toy for simplified indication of directions. It should not be used for serious
applications such as mountain climbing.
• Do not leave the analog compass in places which may reach temperatures of -20°C or lower or 50°C or higher.
• Parts are not guaranteed against natural wear or deterioration resulting from normal use.
The analog compass may not indicate the correct direction in the following cases:
• If it is placed near the outer casing or inner cable of the bicycle (because of magnetism).
• If it is near high-voltage power lines, railroad tracks (including underground tracks), manhole covers or steel
building frames. However, these are not the only objects that may affect the analog compass.
The characteristics of the analog compass mean that it may react to weak magnetic forces and metallic
objects, so be careful to use it in a suitable environment.

Installing the SC-TX30 (speedometer)
First remove the cover of the SM-TX30 that is installed to the handlebar, and then
place the SC-TX30 onto the top of the SM-TX30 and secure it by tightening the fixing
screw.
<Securing the sensor cable>
• Use EZ cable clamps and cable ties to secure
the sensor cable.
• Use a cable length adjuster to take up any
slack in the cable and to secure it to the cable
clamp on the bracket.
Note:
Secure the cable tightly so that it does not stick out from the frame.
Be particularly careful to secure the cable where it runs near the
crank arm.
For the front suspension, allow enough extra length for the
suspension stroke when adjusting the length of the cable.
When routing the cable near the bottom bracket, pass the cable
over the bottom bracket.

• Hook the groove of the magnet holder onto the
intersection of spokes on the left side of the
front wheel as shown in the illustration, and
provisionally secure it there.
• Provisionally secure the sensor to the front fork
with double-sided tape and a cable tie, adjust
the magnet so that it is aligned with either one
of the two grooves on the sensor and so that
the distance between the magnet and the
sensor is 1 - 5 mm as shown in the illustration.
Then secure the sensor and the magnet.

<Shift timing indicator (Tachometer)>
One method of obtaining a comfortable ride is to ride with the front gears at a fixed gear
speed.The SC-TX31 can show the front gear speed in an analog-type display, and the
gears can be shifted within the range set by the "GOOD" position so that a comfortable
ride can be obtained. (When pedaling becomes light, the front gear speed increases, and
when it becomes heavy, the speed decreases.) In general, the three speeds given in the
example are comfortable speeds.
Setting
15 seconds after the battery (CR2032) is inserted, the LCD screen will be displayed.
The rider can move the GOOD mark on the ring to either the right or left in order to
determine the position which is best for the rider.
