When initially powered on the console will perform an internal self-test. During this time all the lights will turn on for a short time. The message window will display a software version (i.e. VER 1.0) and the distance window will display an odometer reading indicating how many virtual miles (or Kilometers) the treadmill has gone. The time window displays how many hours the treadmill has been used.
The odometer will remain displayed for only a few seconds then the console will go to the start up display, also known as Idle Mode. The message window will be scrolling the start up message. You may now begin to use the MT200.
The console will automatically power down after 30 minutes of inactivity. Press any key to wake the console up again. To disable this function so console always remains powered on see Maintenance MT200 is not in use.
The operator will start the device and use the speed and incline keys to control motors. When the speed key is pressed a signal is sent to the AC motor inverter to request a change. The inverter will then send the appropriate amount of power the AC drive motor to reach the requested speed. The motor drives the front roller (which in turn moves the walking belt) through pulleys and fan belt. The incline motor is operated when the operator presses the incline keys. A command is generated that is transmitted to the incline control board where a relay is energized sending AC power to the motor until it reaches the desired position.
Console Key Functions
Entering Patient Information
The Set-up key function will allow you to enter patient data and customize the settings of the MT200. When the set-up key is pressed, the first option in the menu appears. Use the up/down arrows to scroll through the menu. Press the ENTER key to select an option.
When entering patient data, the following fields are available for particular purposes:
- Age: Used in VO2 and heart rate program
- Gender: Used in VO2 program
- Weight: Used in METS, calorie calculations, and VO2 program
- Height: Used in symmetry program
This is the quickest way to start an exercise session. After the console powers up you just press the Start key to begin; this will initiate the Quick Start mode. In Quick Start the speed will be set to zero until the user adjusts the speed. Time will count up from zero, all workout data will start to accrue and the speed and incline may be adjusted manually by pressing the Up or Down key. The dot matrix will display a speed level. As you increase the speed more rows will light indicating a harder workout.
The dot matrix has 24 columns of lights and each column represents 1 minute in the Quick Start program (time per column can be modified in other programs). At the end of the 24th column (or 24 minutes of work) the display will wrap around and restart at the first column again.
Below is a sample picture showing the symmetry graph. In the message window there is an average step cadence, left and right step length and symmetry measurements. In the example below the step length numbers shown indicate that the left leg is stepping longer than the right leg, 26 vs. 15 inches. The graph rejects the longer stride of the left leg. If the step length was even only two dots would be lit on the bottom center of the graphic screen.
Note: For some types of gaits it may be possible that the left/right data can be displayed in reverse. If this occurs press the symmetry program key to flip the display.
