(Position A-2).
Bild B: For using it on the stem, change bracket mounting
orientation from Position A to Position B.
Remove the protective tape.
Place the handle bar and fasten it with the cable ties.
Bild C: Mount the transmitter with cable ties on the fork (max.
distance to the handlebar bracket max. 60 cm; best mounting on
the right side, handlebar bracket and transmitter should be on
the same side).
Bild D: Fix the magnet on a spoke so that it will face the mark on
the transmitter. Adjust the magnet position and fine tune the
sensor if necessary (distance between transmitter and magnet
max. 3 mm).
Bild E: Rotate the CM 4.3 to 45 degree left and install it into the
bracket. Then rotate it 45 degrees right to lock it. To unlock,
rotate 45 degrees to the left.
1.1 Mounting of optional cadence-set
(separately available)
Mount the handlebar as described above on the handlebar or on
the stem.
Place the sensor on the cable on the left chain-brace in height of
the crank with help of cable-ties so that it is still loose enough to
be lined up. Mount the cadence-magnet (with help of a cable tie)
on the inside of the crank. The distance between magnet and
sensor should be max. 3 mm.
The magnets must point directly to the mark on the sensor. Now
switch on the cadence measuring in the setting mode of the
CM 4.3A (see chap. 2.1). Turn crank a few times to check if the
mounting is correct. Now tighten the cable-ties.
2. Preparation

3. Functions
The CM 4.3A has an automatic start/stop when on the handlebar
bracket.
That means, 4 sec. after the first wheel turn the display shows
normal mode and the current speed.
1 minute after the last wheel turn (and without a button is
pressed) the display changes to an “energy save“ mode. During
this mode, only the time is displayed.
If the wheel turns or a button is pushed, the computer will
resume normal functions.
CM 4.3A has got three modes: Bike 1, Bike 2, and Non-Bike
mode.
To switch from one mode to another, simultaneously press
the right and left buttons briefly (switching is only possible if
speed = 0).
The centre display shows ➀ or ➁ depending on whether the
selected mode is Bike 1 or Bike 2. The Non-Bike mode doesn’t
show any figures in the display. The Non-Bike mode can be used
for tours without a bike (e.g. with a dedicated wristlet). It only
shows values which have nothing to do with the bike movements.
To reset all day values, press right and left button for
three seconds.
The CM 4.3A has a three-lined display. In the centre part the
current speed is shown, with a small ➀ or ➁ left beside, that
shows whether the current values are valid for bike 1 or bike 2.
To advance the functions of the upper display, press right
button, to advance the functions of the lower display press
left button.
Always short pressing of the centre button shows the sub-
functions of the function in the lower display.
Important for all sufunctions: display shows settings for
10 seconds befor switching back to main function.
