Figure 19: Hand Held - Chest Strap Heart Rate PCA
Wireless Heart Rate Does Not Work
1
Verify wireless heart rate with a known good chest strap transmitter
or test transmitter. If the heart rate reading is erratic,
incorrect, or absent, continue with step 2.
NOTE: It may be necessary to lean in closer to the console at first to
allow receiver to begin to acquire a heart rate signal.
2
Verify that the HHHR board has the correct operating voltage.
Connect a voltmeter to VCC and Ground on the Power/Signal connector.
The voltage should read between 4.5 and 5.5VDC.
3
Identify other sources of wireless interference signals in close
proximity to the unit (such as Wi-Fi networks, cordless phones,
etc.).
NOTE: Wi-Fi network is transmitting in close proximity to the treadmill
the heart rate system MAY pick it up. Using an ohmmeter, verify that
upper and lower PCAs have a good electrical path to chassis ground.
4
If the above procedures do not correct the problem, replace the
heart rate board.
Possible sources of interference signals include, BUT NOT LIMITED TO:

Wi-Fi Network Routers

Cordless Telephones

Cell Phones

Electronic Dog Fences

Garage Door Remotes

Noisy AC feeds

Florescent light ballasts
