Preparation

Using the buttons:
There are no buttons in the conventional sense on the CM 4.1, the settings are made with the two 'buttons' on the rear of unit.

These buttons can be pressed e.g. with a ballpoint pen (see pict. 7).

Inserting the battery:
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 the setting of the circumferrence with the first value flashing.
(To enter again setting mode, press Set-button for 3 sec. when CM 4.1 is in normal mode.)

The following applies for all settings:

SET-button changes flashing value, STORE-button stores this value and changes to the next value or the next setting display appears.

Setting the wheel circumference

Start setting: 2155 mm
Range: 0000-3999 mm
Adjust with SET- and STOREbutton, continue with STOREbutton.

The wheel circumference can be taken from the following table or measured by yourself.

Measurement of the wheel circumference (U)
(for more precise adjustment):

Make a marker on the front tire and on the floor (e.g. with chalk). Move the bike straight ahead by exactly one tire rotation (for a more precise measurement ensure tire pressures are correct and be seated on the bike) and mark the location on the floor. Now measure the distance exactly between the two markers on the floor to give you the wheel circumference (in mm) – s. pict. 8.

Now display shows km/h (kilometers per hour).

If preferred, change to miles per hour with SET-button, save setting and continue with STORE-button.

After this the display shows adjustable total distance.

Range: 00000-99999 km or mi (kilometers or miles)
Adjust with SET- and STOREbutton, continue with STOREbutton.

Display shows flashing '24' to choose time-display (24 – or 12- hour). 12-hour setting shows A/P in the display when time is shown.


Change with SET-button, store and continue to time setting with STORE-button.

Adjust minutes with SET-button, store with STORE-button and now adjust hours with the SETbutton.

Store the adjusted time with STORE-button.
Now all settings are finished and CM 4.1 is ready for operation.

Functions

The CM 4.1 has an automatic start/stop while riding. When the CM 4.1 is set into the handlebar bracket, the implemented receiver is switched on (but display stays in sleep mode). 4 sec. after the first signal from the transmitter (wheel turn), the display switches on and shows following:

Upper display
average speed
Range 0 – 299,99 km/h or m/h

Middle of the display
current speed (km/h or m/h)
Range 0 – 299,9 km/h or m/h

Lower display
daily distance (DST)
Range 0 – 999,99 km or mi

1 minute after the last turn of the wheel the CM 4.1 changes to sleep mode – upper display shows time and lower display shows total distance (ODO: 0 99999 km or mi).

After receiving the next signal from the wheel sensor, the complete display appears again (also with pressing SET- or STORE-button).
When CM 4.1 is not used, it should be removed from the handlebar bracket to save battery power.

Daily distance and average speed are automatically set to zero after 12 hours without receiving a signal from the wheel-sensor.
Total distance is set to zero by pressing the AC-button on the back of the computer or removing the battery
( Attention : that also will clear all settings in the CM 4.1).
