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 (ie: VER 1.0) and the time window displays how many hours the stepper 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 MS300.
The console will automatically power down after 20 minutes of inactivity. Press any key to wake the console up again. Always disconnect the main power when the MS300 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
The set up key function will allow you to set seat and arm adjustments for various patient heights and customize the settings of the MS300. When the set-up key is pressed, the first option in the menu appears. Use the up/down arrows to scroll through the menu and press the enter key to select an option.
Entering Patient Information
The Set-up key function will allow you to enter patient data and customize the settings of the MS300. 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, press the start key to begin; this will initiate quick start mode. In quick start, the time will count up from zero, all workout data will start to accrue and the workload may be adjusted manually by pressing the up or down key. The dot matrix will display a workload level at the lowest resistance. As you increase the workload more rows will light indicating a harder workout. The unit will get harder to pedal as the rows increase.
The graphic display has 20 columns of lights with each column representing 1 minute in the quick start program (time per column can be modified in other programs). At the end of the 20th column (or 20 minutes of work) the display will wrap around and restart at the first column again. There are 20 levels of resistance displayed in 8 rows of lights.
The stop/reset key provides several functions:
- Pressing the stop/reset key once during a program will pause the program. To resume the exercise session just press the start key.
- If the stop/reset button is pressed twice during a workout the program will end and a summary of information for the exercise session will be displayed.
- If the stop/reset key is held down for 3 seconds the console will perform a complete reset.
- During data entry for a program the stop/reset key performs a previous screen function. This allows you to go back one step in the programming each time you press the stop/reset key.
- The enter key is used for entering data during programming and is also used to scroll through different data in the message window during exercise.
Below is a sample picture showing the symmetry graph. In the message window there is an average watt measurement and it is indicating that the left leg is producing more power than the right leg, 41 vs. 34 watts. The graph re ects the higher wattage of the left leg. If the power is equal in both legs only two dots would be lit on the bottom center of the graphic screen. Press the Enter key to view the Symmetry data.
Note: The symmetry program uses a power table and velocity measurements to generate the watt readings; they are not from direct force measurements.
