OPERATING MANUAL

Congratulations on your purchase!
With the 

CICLOMASTER CM 4.4A you have acquired a wireless electronic bike computer with state of the 

art electronics, the highest level of precision and it is weatherproof. As special features the 

CM 4.4A has an 

optional cadence measurement and an optional heart rate measurement (for this you need separately available 
accessories ).
The Two in One-System: this allows you to use this cycle computer for two different bicycles and view the 
combined total values. 
Please read this operating manual carefully.

-  CICLOMASTER CM 4.4A

-  battery type CR 2032

-  battery cap

-  handlebar bracket 

- transmitter

-  cable ties for mounting

-  spoke magnet

The handlebar bracket can be mounted on the handlebar and also 

on the stem. 

Bild A: Mounting is possible on handlebar (Position A-1) or stem 

(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 4.4A  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.

(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 4.4A (see chap. 2.1). Turn crank a few times to check if the 

mounting is correct. Now tighten the cable-ties.

Warning: whoever carries out sport should have a general medical 

check up on his/her general state of health - especially beginners, 

persons older than 35 years of age and anyone who has suffered 

from illnesses or injuries in the past. It is recom mended that a 

doctor be consulted in any case in the presence of risk factors, 

such as smoking, high blood pressure, high cholesterol values, 

diabetes, lack of exercise and excess weight.

The transmitter belt is hung in the elastic chest belt and fastened 

around the upper body. The transmitter (plastic part with the Ciclo-

logo) should lie over the middle of the upper stomach, immediately 

below the breastbone, so that the logo on the transmitter is legible 

(viewed from the front) (see illustration). The electrodes in the belt, 

to the right and left of the transmitter, must be in contact with the 

skin. Pull the belt tight so that it cannot slip and constant contact 

with the body is guaranteed during movement.

If the CM 4.4A fails to display any heart rate, it probably means 

that there is no contact between the skin and the electrodes. 

Moistening the electrodes and the underlying skin often helps. 

Best results are obtained if electrode gel is used (available from 

pharmacies).

Measurement of the heart rate is only possible if the transmitter 

belt is fitted correctly and the CM 4.4A is within the transmitter’s 

reception range (max. 60 cm).

Insert battery type CR2032 with plus-pole facing up. Close battery 

cap with a coin, being sure not to over tighten. After inserting the 

battery the display will show normal mode.

(If nothing or incomprehensible signs appear in the display, press 

the AC-button on the rear of the computer with help of a ballpoint 

pen or a similar object. Attention: this will delete all values and 

setting).

To quit setting mode press again centre button for 3 seconds in 

any setting. 

(To change the display to german language, press left button short, 

display shows ‚LANGUAGE’. Press centre button to choose this 

function and then switch between ‘English’ and ‘Deutsch’ with 

right button. To store press left button and then get back to setting 

mode with short pressing of right button).

Here you can switch on the powerdown-mode or make a reset 

(delete all values).

Choose with centre button

Switch on the powerdown-mode (e.g. before changing of the 

battery, to save the values).

To switch it on, press right and left button short simultaneously, 

display fades out and CM 4.4A is in powerdown-mode. By short 

pressing of any button, CM 4.4A starts again and displays normal 

mode.

Here you can delete all values (including the total values). For this 

press right and left button short simultaneously, display shows 

‘reset’ and then normal mode. 

If you only want to delete the day values, press right and left button 

for three seconds in normal mode. 

The CM 4.4A 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 4.4A 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 a or b 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.

The optional heart rate measuring works also without speed signal: 

when CM 4.4A is in normal mode (by pressing any button or auto-

start), the heart rate receiver is automatically switched on.

And as long as a heart rate is shown in the display, there is no 

automatically switching to sleep mode. 

The CM 4.4A has a three-lined display. In the centre part the 

current speed is shown, with a small a or b 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.

 is the ideal solution for personalised cardio training 

applied to any sport, from jogging and cross-country running to 

road and indoor cycling.

Improve your fitness? – Lose weight? – Train whilst always taking 

your health into consideration? Everyone will find the correct aim to 

follow in their training. But how do you train to achieve those aims 

in the most efficient possible manner? How do you find the right 

intensity of effort during the training? CICLOInZone

®

 is the optimum 

training ZONE for effort, resistance and weight loss.

 

It calculates the optimum training zone for effort, resistance and 

weight loss. 

The values vary from person to person and they offer a valid 

training support – always staying between 70 % and 85 % of the 

maximum heart rate.

(+/- 5% of tolerance, taking into consideration the actual heart rate 

when at rest and the level of training).

The question of burning fat is seen in the “correct” light with
