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 your
local distributor for further assistance.
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.
Select the Edit User Profile option for the User Profile. Go to
the WIRELESS HR setting and make sure that the current
value is set to ON.
Try moving unit away from sources of interference (TV, Micro-
wave, etc).
If interference is eliminated and HR does not function, replace
strap.
If HR still does not function, replace Console.
Make sure that the HR receiver is not blocked by a personal
electronic device in the left side of the media tray.
All wires in cable should be intact. If any are cut or crimped,
replace cable.
Be sure cable is connected securely and oriented properly.
Small latch on connector should line up and snap into place.
Magnet should be in place on pulley.
Speed sensor should be aligned with magnet and connected to
data cable. Realign sensor if necessary. Replace if there is any
damage to the sensor or the connecting wire.
