PROBLEM: The chest pulse sensor does not function properly
SOLUTION: a. If the chest pulse sensor does not function properly, see CHEST PULSE SENSOR TROUBLE-
SHOOTING on page 9.
b. If the chest pulse sensor still does not function properly, the battery
should be changed. To replace the battery, first locate the battery
cover on the back of the sensor unit. Insert a coin into the slot in the
cover, and turn the cover counterclockwise to the “open” position.
Then, remove the cover.
Next, remove the old battery from the sensor unit, and insert a new
CR 2032 battery,
with the battery oriented so the writing on top.
Make sure that the rubber gasket is in place in the sensor unit. Then,
reinsert the battery cover and turn it to the closed position.
PROBLEM: The shock does not assist the lowering of the treadmill frame
SOLUTION: a. Environmental factors such as cold temperatures can affect the performance of the shock. To re-
store shock performance, hold the ends of the frame near the endcaps firmly with both hands,
and carefully lower the frame to the floor and then raise it several times.
To decrease the possi-
bility of injury, bend your legs and keep your back straight.
