1 - CICLOMASTER CM 423i
2 - Handlebar bracket (with O-rings for mounting)
3 - Transmitter (with cable tie for mounting)
4 - Spoke magnet
5 - Transmitter belt (heart rate transmitter)
6 - Elastic chest belt (adjustable)
1. General
The CM 423i switches to standby mode if no wheel or heart rate pulse is
received for 15 minutes. Then the display only shows the time. If any button or a
signal is received from the built-in movement sensor (reacts when the device
moves, e.g. by use of the handlebar mounting or if the wheel moves) the CM
423i switches into normal operating mode (this also activates the speed and
heart rate receiver).
Caution: Basically, anyone who begins fitness training should undergo a health
check, but this applies particularly to beginners and persons starting again, who
are over 35 years old and have known previous illnesses or physical complaints.
In particular, if there are also risk factors present, for example smoking, high
blood pressure, increased blood fat level, diabetes, sedentary lifestyle and an
overweight condition, it is absolutely necessary that a doctor be consulted.
Wearers of a heart pacemaker should only use heart rate monitoring
devices with their doctor’s agreement!
Heart rate monitoring is only possible if the chest belt with the transmitter is
worn correctly (see Chap. 2.2) and the CM 423i is within the range of the
transmitter (max. distance 70cm).
The heart rate can also be measured if the CM 423i is not mounted on the
wheel.
2. Preparation
Inserting the battery:
Insert battery type CR2032 with the positive terminal facing up. Close battery
cap with a coin. After inserting the battery, the display will show all segments
briefly, then display shows “km/h” with a flashing value (to set the unit of
measurement, see Chap. 3.1 below).
If no symbols at all or meaningless symbols appear on the display, remove the
battery and re-insert it.
2.1 Mounting of handlebar bracket and transmitter
The handlebar bracket can be mounted on the handlebar or stem (see pictures).
Picture 1: Mounting is possible on the handlebar bracket (Position A) or on the
stem (Position B).
Picture 2: Change bracket mounting orientation from Position A to Position B.
Picture 3: Fasten one side of the bracket
Picture 4: Remove the protective tape
Picture 5: Stretch the rubber ring under the handlebar and fasten it to the other
side of the bracket.
Picture 6: Secure the sensor on the fork by tightening the cable ties and cut off
the loose ends (max. distance between transmitter and handlebar bracket is 60
cm.; preferably mount on the right-hand side, handlebar bracket and transmitter
should be on the same side)
Picture 7: Fix the magnet on a spoke so that it will face the sensor.
Picture 8: Adjust the magnetic position and fine-tune the sensor if necessary
(Max. distance 5 mm)
Picture 9: Rotate the CM 423i a quarter-turn to the left and install it into the
bracketThen rotate it a quarter-turn to the right to lock it. To unlock it CM 423i,
rotate a quarter-turn to the right and remove from the handlebar bracket.
2.2 Wearing the transmitter belt
The transmitter belt is inserted in the
elastic chest belt and worn around the
upper part of the body. The transmitter
(plastic part with writing) should be
positioned over the middle of the
stomach at the base of the breastbone
and the writing on the transmitter must
be legible (when seen from the front) (see
picture). The electrodes built into the left
and right side of the transmitter in the
belt must be in contact with the skin.
Tighten the belt so that permanent contact is guaranteed during movement, and
the belt cannot slip.
If the CM 423i does not display any heart rate, this may be due to a lack of
contact between the skin and the electrodes. It often helps if the electrodes and
the underlying skin are moistened. The best contact is obtained with an
electrode gel (available from pharmacies).
Congratulations on your purchase!

7. Servicing and care
Protect against direct sunlight, heat and frost (below 0°C and above 50°C).
Cleaning the heart rate transmitter belt:
The transmitter belt with its built-in special electrodes cannot be washed in a
washing machine. Wipe the transmitter belt carefully with a synethetic
detergent. Do not leave to dry in blazing sun. The elastic chest belt itself is
washable, but must be dried well before use.
