Your Rokai has been fitted with a built-in wireless heart rate receiver that's compatible with uncoded, standard frequency transmitters. An example of a compatible transmitter is the Polar T31 uncoded transmitter.
To get a heart rate reading using a chest belt, put the chest belt on, positioning in the middle of your chest just above the solar plexus. There is no need to pair the transmitter to the receiver.
Get on the Rokai and begin your workout. The chest belt will automatically send out a signal that the wireless receiver will pick up. Your heart rate will be displayed on the screen.
There are a few reasons why you may get erratic readings when trying to use a chest belt to measure your heart rate. If you are getting erratic readings or no readings at all, then in the first instance Please check the following:
1. Make sure that the chest belt you are trying to use is an UNCODED transmitter. Attempting to use a CODED chest belt transmitter will result in either no readings at all or erratic readings. If you are using a chest belt that came with a sports watch then the chest belt is most likely a coded belt and will not be compatible. We'd recommend a model such as the Polar T31 Uncoded transmitter (this is also available as a coded version so make sure to choose the uncoded version when purchasing)
2. Check the battery in the chest belt. A weak battery will result in erratic readings or no readings at all. Some transmitters have batteries you can change, other transmitters are sealed and the batteries cannot be changed.
3. Make sure that there is good contact between the chest belt and your skin. To work, the chest belt needs to be placed directly on the skin. It's often worth slightly wetting the back of the transmitter to ensure proper contact is made.
When working correctly, it can take up to 30 seconds for the signal to register on the console of the machine.
