COMPUTER INSTRUCTIONS /
USING A CHEST-BELT
STANDBY MODE:
The computer will go into standby mode after about 4 minutes of inactivity.
BATTERIES:
The computer uses 4 AA batteries, which are included. Changing the batteries will reset all values.
If there is a problem with the display, try changing the batteries first. When changing the batteries,
change both of them. Do not mix battery types. Do not mix old and new batteries. Dispose of old
batteries according to your regional guidelines.
Using a chest-belt
A compatible chest belt is able to detect your heartrate and will transfer this information to the
computer by wireless signal. Each heart rate signal received by the built-in receiver will be accom-
panied by a flashing heart symbol. The measurement with a chest belt (optional) is a very accurate
measurement and is unaffected by disturbances. The wireless signal is transmitted via low fre-
quency (5.3 kHz) tech-nique. Maximum transmission range: 130 cm. The chest belt needs 1 pc. of
CR2032 battery.
How to wear the chest belt
You may adjust the strap to a comfortable length. However, the electrodes must have contact with
your skin in order to measure your heart rate correctly. It may last up to one minute before a correct
display can be seen. Moisten the electrodes slightly before wearing the strap. This increases the
contact sensibility and enables a better wireless signal transmitting.
Hint: The battery compartment lid should face the outside when wearing the belt
Battery replacement:
Open the battery case cover on the back side of your transmitter and replace the old battery by a
fitting new one (CR2032). Ensure correct polarity when inserting. Close the case cover properly.
Remarks
1. If your skin is too dry, the chest belt may not be able to measure your pulse rate correctly. Mois-
ten your skin and the electrodes slightly and try again.
2. If your chest hair is too dense, the chest belt may not be able to measure your pulse rate correct-
ly. Please only use the belt if your chest hair is not too dense.
