First, check the items as described in the section [Trouble-Shooting
and Handling Care] of the Operating Instructions which comes with
the Wireless Chestbelt Pulse Sensor Kit.
When the symptom does not go with those items, proceed to the
following checks.

1. Turn on the power to display the in-training screen (any exer-
cise program).
2. Install a new transmitter on the chestbelt as described in the
operating Instructions for the Wireless Chestbelt Pulse Sensor
Kit.
Check if your pulse rate will be displayed.
[Judgment]

mitter might be defective. In this case, you need to take
actions as specified in the repair method (a) described at
the right.
When the heart rate cannot be displayed, proceed to the following
checks.

cable, from the cable inlet at the back of the control unit. (Fig.

4. Remove ten screws at the back of the control unit and remove
the rear panel of the control unit. (Fig. 2)
5. Check that connectors at both ends of the connector cable
which connects the receiver board and the board within the
