New WearLink found. Teach new WearLink?
If you have purchased a new transmitter as an accessory, it will have to be introduced to the training
computer. For further information, see Teach a New Transmitter (page ).
If the transmitter you are using is included in the product set, and the text appears on the display, the
training computer may be detecting the signal of another transmitter. In that case, make sure you are
wearing your own transmitter, that the electrodes are moistened, and that the transmitter belt has not
loosened. If the message still appears, the battery of your transmitter is empty. For further information,
see Care and Maintenance (page 60).
