Solar Radio-Controlled Cyclometer
Version 05/09
Item-No. 84 14 08 °
Intended use
The product is intended to be used for measuring and display certain data on a bicycle (e.g. speed, mileage).
A magnet is mounted on the front wheel. A radio sensor recognizes the revolutions of the wheel and sends a
radio impulse to the cyclometer.
In addition, there is an integrated thermometer and stopwatch, furthermore the fat and energy consumption
can also be displayed. With sufficient sunlight the integrated solar cell provides the power for the cyclometer.
The cyclometer and its accessories are only suitable for use on a standard bicycle . Installation and operation
on another vehicle, e.g. a motorcycle is not permitted!
The product is intended for private use. It is not suitable for commercial use. Use of this device in any other
way than described above is not permitted.

Safety Instructions
Please read all of the operating instructions before using the product for the first time;
they contain important information on correct operation. The warranty will be void in the
event of damage caused by failure to observe these safety instructions! We do not
assume any liability for any consequential damage!
We do not assume any liability for material and personal damage caused by improper
use or non-compliance with the safety instructions!
The warranty will be void in such cases.
• For safety and approval (CE) reasons, unauthorised conversion and/or modifications to the
product are not permitted. Never take the product apart (except to change the batteries, as
described in these operating instructions).
• The product is not a toy. Keep away from children.
• Do not leave packing materials unattended. They may become dangerous playthings for chil-
dren.
• Handle the product with care, it can be damaged by impacts, blows, or accidental drops, even
from a low height.
Battery notes
• Keep batteries out of the reach of children.
• Observe the correct polarity when inserting the battery (positive /+ and negative/-).
• Do not leave batteries lying around in the open; there is a risk of them being swallowed by children or domes-
tic animals. If swallowed, consult a doctor immediately.
• Leaking or damaged batteries can lead to caustic burning of the skin. Therefore, use suitable protective
gloves.
• Ensure that the batteries are never short-circuited, taken apart or thrown into a fire. There is a risk of explo-
sion!
• Do not recharge normal batteries. There is a risk of explosion!
• If the device is not to be used for a long time (e.g. storage) remove the batteries.
Old batteries can leak and cause damage to the product; loss of guarantee/warranty!
• For the correct disposal of batteries, please read the chapter “Disposal”.
Starting Up, Inserting Batteries, Replacing Batteries
• The batteries have probably been already inserted by the manufacturer. To activate the cyclometer, simply
press any key to show the display. Alternatively, remove the batteries and replace them again.
• When batteries are to be inserted or exchanged
open the battery compartment, on the bottom of
the product, by turning the battery compartment lid
to the left and removing it.
• Insert one battery, of type CR2032, into the
cyclometer and into the sender with the correct
polarity (Observe Plus/+ and Minus/-, the positive
pole (+) always points to the outside).
• Replace the lid of the battery compartment and lock it by turning it to the right.
• The battery needs to be replaced if the display contrast is poor, or nothing is displayed, or no data is received
from the sender (to test, swap the batteries).
• Dispose of the batteries with respect for environmental protection (see section “Disposal”).

Installation
• First, mount the cyclometer mounting bracket (A) to the handlebar, as illustrated in figures 1a, 1b and 1c.
Use the two cable binders (D) for fixing. The nose in the centre of the bracket (A) points to the saddle.
• Then, mount the radio sensor (B), also using two binders, on to the left or the right part of the front wheel
fork, see figure 2.
• The magnet (C) is fixed to a spoke of the front wheel. Depending of the spoke’s shape (round or elliptic) use
the appropriate opening, figure 3.
The magnet must rotate directly over the label “SENSOR“ on the radio sensor (observe the direction of the
arrow). Move the magnet if necessary and refasten it at the right spot.
When it passes the radio sensor, the distance to the magnet should not exceed 2 mm, otherwise the sen-
sor in the radio sensor may not correctly detect the magnet. Make sure the magnet does not rub against the
radio sensor.
Determining the wheel perimeter/wheel diameter
In order to obtain the exact value for the distance and speed, the wheel perimeter or the wheel diameter has
to be determined. We recommend using the wheel perimeter, since it is more accurate.
Find an even, smooth surface (e.g. garage). Mark a given position on the wheel, do the same on the ground
(point A). Now, move the bicycle forwards, until the wheel has made a completed revolution, and mark the spot
on the ground (point B).
Measure the distance between the points A and B, to obtain the wheel perimeter, which is entered later into
the cyclometer (value in millimetres).
If you want to use the wheel diameter, the wheel perimeter is calculated as follows:
Diameter in millimetre * 3.1416 = wheel perimeter
Diameter in inches * 2.54 * 3.1416 = wheel perimeter
Example: 26 inches * 2.54 * 3.1416 = wheel perimeter 2075 mm
