Be careful not to pay excessive
attention to the computer data while
riding, otherwise you might have an
accident.
NOTE;
* The all clear (AC) button is used to clear the main unit memory.
* Never disassemble the main unit, as it cannot be reassembled.
* The main unit is fully waterproofed to withstand wet weather
conditions; however, do not deliberately place it into water.
* Avoid leaving the main unit exposed to extremely hot weather
conditions.
* Handle the main unit carefully, and avoid subjecting it to any shocks.
* Do not use thinner or other solvents to clean parts such as the main
unit and sensor, as they may dissolve the part casings.
* To clean these parts, wipe them with a cloth soaked in a weak mixture
of neutral detergent and water.
* If using the SM-6501/M/MD together with an LED lamp from another
manufacturer, the speed measurement function may not work
correctly.
If using an LED lamp from another manufacturer, it is recommended
that you use the SM-6500-RS.

• If the trip time exceeds 100hours or the trip
distance exceeds 1,000kilometers (620miles),
“ER”will be displayed and the pace arrow
comparison will disappear. However, TIM
and DST measurements will start again from
zero and the MAX speed will be retained.
Pace Arrow
Moves when distance time is
operating.
The upward arrow indicates that
the current speed is faster and
the downward arrow indicates
that the current speed is slower

function.
Maximum speed (MAX,STW) records the Maximum speed during the stopwatch
function.
Displays the cumulative distance
travelled.
Note;
The functions of this group are
only available when
stopwatch is activated.
If the trip distance mode is
also activated simultaneously,
it is not possible to view at the
distance. However the trip
distance, average speed and
maximum speed will still be
recorded during this time.

these procedures.
* For the SM-6501-M, SM-6501-MD refer to the Service Instructions included.
(1)Installing the signal cable (SM-6501)
Install the signal cable as shown
in Figure No1.
SM-6501
Tape the signal cable to the
handlebars.
(2)Installing the computer
Install the band and the bracket as
shown in Figure No2.
(3)Slide the computer onto the
bracket until it clicks into its
place.

8. Data input ( * data for up to 4 bicycles can be entered)
First measure the tire circumference and check the number of chainring and
sprocket teeth.
To measure the tire circumference,first ensure that the tire is inflated to the
standard tire pressure. Make a mark on the tire and the ground at the point where
the tire touches the ground, and move the bicycle forward one full revolution of
the front wheel while seated on the bicycle, Mark the point where the marking on
the tire touches the ground again. Measure the distance between the two points
in millimeters. Round the distance to the nearest multiple of 5mm.

(4)Installing the magnet and
sensors
Use a screwdriver to temporarily secure
the magnet to a spoke on the right hand
side of the front wheel as shown in fig4.
Put a rubber shim between the fork and
the sensor as shown in fig5.
(Fork diameter range is 11-35mm)
Place the magnet on the sensor line as
shown in the illustration.
Adjust the position of the magnet so that
the distance between the magnet and the
sensors is 1--5 mm. Secure the magnet
and the sensors firmly in these positions.
Set the positions so that the distance
between the meter and the sensor
are within the following:
Vertical: 50 cm
Horizontal: 10 cm

(3)Entering the tire circumference
The display will change as shown in Fig. 8.
Press switch “A”to display the bicycle
number that you would like to change, and
press switch “B”for 2 seconds or more.
Because of the preset chainring and sprocket
tooth configurations used, bicycle numbers 1

Enter the number of teeth for the
inner chainring (for double front
chainwheel) or the middle
chainring (for triple front
chainwheel).
“38”(or “32”if no. 3 or 4 has been
selected) will flash on the display.
This position can be set from 20 -
50 by the same procedure of
setting outer chainring. After
setting the inner chainring or the
middle chainring, the display will
change to that shown in fig12.
Enter the number of sprocket
teeth.
The display will then change to
that shown in fig13.
When using a double front chainwheel, press switch “A”once so that “--”
is displayed, and then press switch “B”once to set, the front chainwheel
will then be registered as a double front chainwheel and the display will
change to show the rear sprocket settings.
(Note: Switch “B” should be
pressed and released immediately. If you press it for more than 2
seconds, the next rear derailleur type will be displayed for data entry.)
When using a triple front chainwheel, the value can be set from 15 to 34
by the same procedure of setting middle chainring.
Enter the number of teeth for each
sprocket by the same procedure as
that used for the chainrings.
Press switch “A”to set the desired
number of teeth, and then press
switch “B”to accept the setting.

there is no 8th sprocket, and the operation for entering the number of
sprocket teeth will be complete.
If the cassette has 8 sprockets, enter the number of teeth for this position
and follow the same procedure as above to enter “--”in the 9th position
otherwise enter the number of teeth for the 9th sprocket.
Checking the number of teeth entered
Once the setting of number of sprocket teeth is completed, the display will
return to the initial input display. Re check all values by repeatedly
pressing switch “B”to confirm each number of teeth. Press switch “B”
once each time and check whether the entered number of teeth are
matching with the sprocket
position on the display.
If all values entered are
correct, press switch “B”for 2
