Procedure 2.2

- Displaying the Treadmill Odometer

This procedure displays total distance (in miles or kilometers) the treadmill has operated. The
odometer cannot be reset.

Note:

The odometers get updated at the end of the course. If a user shuts off the unit while in the
middle of a course, the odometer will not be updated and the user will have essentially lost the
mileage for that session. Pressing

RESET

displays the

PRECOR C944

banner and accumulates

the mileage.

Procedure

1.

Plug the power cord into the wall outlet, then turn on the treadmill with the circuit breaker.
