HRC TROUBLESHOOTING
The heart rate receiving hardware consists of two components, the receiver or pulse
PCB (part #70283) and the pulse cable (part #70313). The pulse cable connects the pulse
receiver to the upper display board.
Before attempting to troubleshoot the “receiving portion” of the HRC feature,
CONFIRM
THE TRAMSITTER BELT IS WORKING PROPERLY
. You can test the user’s transmitter belt
on another Landice treadmill or a Polar
®
wristwatch. If the transmitter is faulty, replace
battery or return to Landice for replacement (if treadmill is under warranty).
If the transmitter belt is functioning properly, proceed with the following steps.
1. UNPLUG THE TREADMILL!
2. Remove the right hand upright cover to gain access to the heart rate components.
3. Confirm the heart rate components are present and in good visual condition.
4. Remove pulse cable from PCB board. Check for loose wires or bent/faulty pins. If all
looks good, reconnect pulse cable to PCB card.
5. Remove pulse cable from Upper Display board (you will have to open control panel
to gain access). Check for loose wires or bent/faulty pins. If all looks good, reconnect
pulse cable to Upper Display board.
6. Test the HRC feature for proper operation.
7. If the HRC does not work replace the pulse cable (part#70313) and pulse PCB
(part#70283)
