Make sure unit is plugged into a functioning wall outlet.
Connection should be secure and undamaged. Replace
adapter or connection at unit if either are damaged.
All wires in cable should be intact. If any are visibly crimped or
cut, replace cable.
Be sure cable is connected securely and oriented properly.
Small latch on connector should line up and snap into place.
Check for visual sign that console display is cracked or other-
wise damaged. Replace Console if damaged.
If Console only has partial display and all connections are fine,
replace the Console.
If the above steps do not resolve the problem, contact Cus-
tomer Service (if inside US/Canada) or your local distributor (if
outside US/Canada).
Be sure cable is connected securely to Console.
Be sure hands are centered on HR sensors. Hands must be
kept still with relatively equal pressure applied to each side.
Sensors may have difficulty with dried out or calloused hands.
A conductive electrode cream (heart rate cream) can help
make better conduct. These are available on the web or at
medical or some larger fitness stores.
If tests reveal no other issues, Handlebars should be replaced.
Strap should be "POLAR®" compatible and uncoded. Make
sure strap is directly against skin and contact area is wet.
If strap has replaceable batteries, install new batteries.
