Attaching the handlebar bracket
You can attach the computer to the right or left of the handlebars or in the centre on the stem. Attach the handlebar bracket in the corresponding position.
STEP 1
Decide whether you want to attach the computer to the handlebars or the stem.
STEP 2
Rotate the foot of the handlebar bracket by 90° accordingly. To do so, undo the screws in the bracket, remove the foot and rotate it 90° then insert and tighten the screws again. Attention: do not overtighten the screws.
STEP 3
Guide the cable ties through the slot in the handlebar bracket, place around the handlebars or the stem and pull (do not pull tight just yet).
STEP 4
For handlebar attachment: align the computer angle to achieve optimum readability. Now pull the cable ties tight.
Use clippers to snip off protruding ends.
Attaching the speed transmitter
The transmitter can be attached to the fork leg on the right or left.
Note:
If you have attached the computer to the stem or the left of the handlebars, the speed transmitter MUST be attached to the LEFT fork leg.
STEP 1
Place the rubber shim under the transmitter. Fit the transmitter on the same side of the forks where you later want to fit the computer to the handlebars (right or left) using the cable ties supplied (loosely at first, do not pull tight just yet).
ATTENTION: The cross-hatched marking on the lid of the transmitter's battery compartment must point toward the spokes.
Depending on the available space, the transmitter can be mounted along the front of the fork, on the inside of the fork, or the back of the fork.
STEP 2
Place the spoke magnet around an outside spoke. The VDO logo of the rod-shaped magnet core should point toward the transmitter. Align the magnet with the cross-hatched sensor marking on the transmitter at a distance of 1-5 mm.
STEP 3
Align the transmitter and magnet in their final positions and fasten them in place:
pull the cable ties tight and push the magnet in firmly.
The transmitter should be folded down at a maximum angle of 45^ to the spokes. If you cannot achieve this angle, move the transmitter down along the fork leg towards the hub until you have reduced the angle to less than 45^ .

The VDO M4 WL automatically pairs the transmitter.
Once the computer has been rotated into place in the bracket, it starts searching for the transmitter.
The transmitter search is identified by the flashing digits for:
- Speed
- Heart rate (if the heart rate option is activated)
– Cadence (if the cadence option is activated)
The VDO M4 WL has an automatic bike recognition function. Depending on whether you are using bike 1 or bike 2, the data is recorded for bike 1 or bike 2.
ATTENTION: When other radio signals interfere during the pairing function, the display shows the message "Too Many Signals".
Confirm this message by pressing any key. You will then need to leave this location and move to another location. Untwist the computer from the handlbar bracket. Then reinsert the computer into the handlebar bracket. The computer will now attempt another pairing.
Potential source of interference:
- LED lights
- Mobile telephone
- GPS receiver
- WLAN
– Anti-theft security systems inside the store
These sources can interfere with the pairing.
ATTENTION: when using the transmitter for the first time, the bike recognition switch must be set to either BIKE 1 or BIKE 2. Only then will the automatic bike recognition work.
Press and HOLD the button until the LED flashes.
Green flashes once = bike 1 is selected
Red flashes twice = bike 2 is selected

Settings – wheel circumference/wheel size
You can set the roll circumference of your wheel in millimetres on the VDO M4 WL or select the applicable tyres from a tyres table.
The more accurate this setting, the more accurate your speed indicator and the measurement of the distance you have travelled. You can find the values for your tyres in the tyre size table and set these in the device.
ATTENTION: the values in the table are approximations only. The actual values can deviate from the values in the table depending on the manufacturer and the tyre tread.
If your tyre size is not listed in the table, you can accurately measure the roll circumference.
How to measure the roll circumference:
STEP 1
Stand your bike up and position the wheel to which you want to attach the sensor so that the valve is directly on the ground. Ensure that the tyres are fully pumped up in accordance with the usage instructions. Mark the position of the valve on the ground with a line or adhesive strip.
STEP 2
Now push your bike forwards in a straight line until the valve is back on the ground after one rotation.
Again mark the position of the valve on the ground with a line or adhesive strip.
STEP 3
The distance between the two marks corresponds to your wheel circumference or wheel size in millimetres.

– Maximum gradient uphill
- Altitude loss
– Average gradient downhill
– Maximum gradient downhill
Recalibrating the altitude before starting
Why is it necessary to recalibrate the M4 WL?
The M4 WL measures the current air pressure and converts it into an altitude measurement. The air pressure changes daily depending on the weather. This leads to a constantly changing current altitude measurement
HOWEVER: your home start altitude has not changed.
During recalibration, the currently measured air pressure is recalculated on the basis of a reference value – the preset start altitude for your home.
Following recalibration, the M4 WL again correctly displays the start altitude as the current altitude.
To calibrate the cycle computer, press and hold the ALTI button until the menu opens.
"Altitude SELECT" flashes on the display.
You can now choose whether you want to:
- set the current altitude to the correct value
- set the current sea level pressure to the correct value
- use the start altitude 1 as the reference value for the recalibration
- use the start altitude 2 as the reference value for the recalibration
Press the BIKE or ALTI button to scroll to Home Alti 1 or Home Alti 2 depending on where you are setting off from. Press the SET button to confirm the desired start altitude.
The M4 WL now stores the preset values and displays the start altitude as the current altitude at your present location.

B --> C["Air Pressure 10 15.1"]
C --> D["Home Alti 1 580"]
D --> E["Home Alti 2 400"]
Recalibrating the altitude before starting
In addition to choosing between the two start altitudes, you can also enter a value under "current altitude".
Do this if you are not setting off from either start altitude 1 or start altitude 2.
Press the SET button to select "Actual Alti". The setting opens.
Press the BIKE button to increase the value. Press the ALTI button to decrease the value.
Once this value has been set, confirm the setting by pressing the SET button.
The confirmation message "Set OK" appears on the display.
The newly set value for the current altitude is now displayed.
Recalibrating the altitude before starting
Making an entry based on the air pressure is practical if you are at a location where you do not know the precise altitude.
On the M4 WL, the sea level pressure is recalculated to the current altitude.
Details of the sea level pressure for your current location can be found on several weather websites.
Press the SET button to select the setting for the Air Pressure.
The setting opens.
The current sea level pressure is displayed.
Press the BIKE button to increase the value. Press the ALTI button to decrease the value.
Once this value has been set, confirm the setting by pressing the SET button.
The confirmation message "Set OK" appears on the display.
The new altitude is now displayed.
Switching the backlight mode on or off
The M4 WL has a backlit display.
To use the backlight, the backlight mode must be activated.
How to activate the backlight mode:
Simultaneously press the ALTI and SET buttons.
The backlight mode is now activated.
This is indicated by the light icon on the display.
When the backlight mode is activated, each time a button is pressed, the display backlight illuminates for a few seconds. Pressing the same button a second time displays the desired function.
ATTENTION: to conserve the battery, the backlight mode is deactivated if the M4 WL goes into sleep mode during a rest period.
This ensures that you do not unnecessarily drain the battery by having the backlight mode activated during the day, for example.
You can also switch the backlight mode off again manually.
To do so, simultaneously press the ALTI and SET buttons.
The light icon disappears from the display.
Battery status indicator
The VDO M4 WL has a low battery warning.
If the remaining battery capacity falls below a certain level, a warning appears on the display.
Press any button to clear the warning.
Following a low battery warning,
you still have approx. 2 weeks to replace the battery.
Replacing the battery in the computer
To ensure your cycle computer is fully functional, we recommend replacing the battery annually.
ATTENTION: your settings as well as your total distance, total ride time and altitude gain/loss for the year remain stored when you replace the battery. NO data is lost.
You need a 3 V 2032 battery.
We recommend using a branded battery from Sony, Panasonic, Varta or Duracell.
How to replace the battery:
STEP 1
Use a coin to remove the battery compartment cover.
STEP 2
Remove the dead battery.
ATTENTION: Wait for 10 seconds before inserting the new battery. The electronics need this time to recognise that the battery is being changed.
STEP 3
Insert the battery into the computer housing with the +pole up.
Ensure that the battery is not tilted.
Ensure that the rubber seal lies smoothly on the lid of the battery compartment.
STEP 4
Insert the battery compartment cover into the opening and use a coin to turn it to the right as far as it will go.
