5. Install new combo heart rate PCB in location shown in the drawing at the

top of this procedure. Note: The placement is very critical. The

antenna will not pick up a wireless transmitter if the placement is off.

6. Plug the hand grip cables (P2745 on SXT’s or P2775 on SX’s) into the

new combo heart rate PCB. Note: The top pin is not used. The cable

header with the “L” written on it plugs into the next two prongs of the

contact heart rate header. The next pin is not used. The cable

header with the “R” gets plugged into the bottom two prongs.

7. Plug the heart rate cable (P2309) back into the combo heart rate PCB.

Note: This plugs into the top three prongs of the heart rate to upper

PCB header. The bottom four (4) prongs are not used.

8. Plug the other end of the heart rate cable into the wireless heart rate

header on the upper PCB (P2160). See picture below.

9. Reconnect all cables to the upper PCB.

• The ribbon cable plugs into the bottom ribbon cable header on the

right side of the upper PCB (as shown in the drawing).

• The FITKEY ribbon cable (P2418) plugs into the FITKEY ribbon

cable header on the upper PCB. This header is located just above

the contact heart rate header (as shown in the drawing).

• There are two (2) gray Telco cables. The cable from the 8VDC jack

affixed to the console back connects to the 8-pin, +8VDC power

header on the upper PCB. The other cable from the COMM jack

affixed to the console back connects to the 8-pin, C-Safe header.
