• Large magnetic fields could affect the calibration or readings
• Care should be taken not to drop the ROMI.
• The plane of motion should be consistent and relative to the device
• This device uses a Lithium-Ion battery as a power source. It is recommended that the battery be charged at least once every six months. Failure to periodically charge the  battery may result in battery damage or device malfunction.

Charging

The low battery indicator screen is shown when the battery needs to be charged. The screen will be displayed and then the system will power off. This screen will be displayed when the power button is pressed until the unit is recharged via the USB-C connector. The device should take about one (1) hour to charge 80% of the capacity, or  about three (3) hours for a full charge.

Function Buttons

The ROMI has five function buttons that control the menus and allow the selection of options and settings.

1. POWER/MENU/SELECT Button: The Round MENU/SELECT button is located on the bottom middle of the ROMI. This is the button used to power on the  device. Holding the MENU/SELECT button for 5 seconds will power off the unit. It is placed for easy access regardless of right or left hand operation. The  MENU/SELECT allows you to enter into the Menu screen and select various options within it.

2, 3. NAVIGATION Buttons: : While on the Test screen the NAVIGATION buttons are used to undo a trial or delete a test. While in the Menu screen, the  NAVIGATION buttons are used to navigate the various menu screens.
4, 5. BASE buttons: On the Test screen the BASE buttons are used to START/STOP tests and SAVE results when applicable. On the menu screen these buttons are used  to return back one screen, BACK, or return to the Test screen, TEST. These buttons can be flipped for a specific dexterity by changing the button orientation in the OPTIONS menu.

Screens Test Screen

The Main Measurement Screen shows all measurement information that is being captured. This screen is shown whenever a measurement is in progress.

1. Battery Indicator: Indicates the remaining capacity in the charge of the battery.

2. Angle Display: Displays the current angle read during a test or the last trial while not testing.

3. Wireless Communication Indicator: This character indicates when the wireless is enabled.

4. Time Display: This time is displayed and can be set manually or synced with a PC in the Options Menu.

5. Sound Indicator: Indicates whether beeper is on or off for the current test.

6. Test Number: Displays the test number while a test is being displayed.

7. Axis of Rotation: Displays the axis of the current test relative to the device.
   • ROT: Rotation around the device
   • F/B: Front to back orientation
   • L/R: Left to right orientation

8. *SAVE: In this example, represents the label for the right BASE button. Save will save the current test.

9. *DELETE: In this example, represents the label for the UP arrow button. Delete will remove all current trials without saving.

10. *UNDO: In this example, represents the label for the DOWN arrow button. Undo will remove the last trial without saving.

11. *START/STOP: In this example, represents the label for the left BASE button. Start will start a new trial. Stop will stop the current trial and add it to the trial list.

12. Trial List: This window displays the trial number and the angle the trial was ended on.

• Indicates button mapping for option will change depending on chosen button orientation – set in OPTIONS menu

Dual Setup Menu Screen
The Dual Setup menu allows users to connect two (2) devices together for dual inclinometer. Once selected from the main menu, the device will scan for other devices  nearby. This could take 20-30 seconds. Once the scan is finished, all found devices are displayed on the screen. Use the navigation buttons to select the device to connect.

Once the main device connects to the companion unit, the screen on the companion will display “Connected To Peer Device”.
Once connected, navigate back the test menu on the main device and run normal tests now using both the main and companion units. The main device dictates the  orientation of the trial. When beginning a test, the main device and companion unit should start in the same orientation and plane. The main device will automatically  calculate the combined angle and display it on the screen

To disconnect the devices, select the Dual Setup icon in the main menu. Once the devices are disconnected from each other, they can be used individually for single inclinometer.

Saved Data Menu Screen
The Saved Data menu allows users to manage tests that have been saved in the internal memory.

Options Menu Screen
The Options menu allows user to customize the setup of their unit.

• WIRELESS: Toggles on/off the module for wireless connection.
• BACKLIGHT: Toggles unit’s backlight on/off.
• SOUND: Toggles unit’s sound on/off.
• BUTTON ORIENTATION: Switches the functionality of the base buttons, allowing for use in either hand.
• LOCK ANGLE: Changes the angle that locks the device in its axis.
• DATE: Updates the ROMI system date.
• TIME: Updates the ROMI system time.

Information Menu Screen
The Information menu provides a contact email and various information about the ROMI.
Sensor Calibration
The sensor performs self-calibration, but the device also monitors the current calibration status both when the test window opens and at the beginning  of a trial. The calibration window is displayed when the calibration status shows it is not fully calibrated. The window displays three letters for each sensor followed by the number  representing the calibration status (0-3) as shown here:

Accelerometer (A)
If this sensor needs calibration, place the device in 6 different stable positions for a period of few seconds to allow the accelerometer to calibrate. Make sure that there is slow  movement between 2 stable positions. The 6 stable positions could be in any direction, but make sure that the device is lying at least once perpendicular to the x, y, and z axis.
Gyroscope (G)
If this sensor needs calibration, place the device in a single stable position for a period of few seconds to allow the gyroscope to calibrate.
Magnetometer (M)
If this sensor needs calibration, make random movements (for example: writing the number ‘8’ in air) until sensor is fully calibrated.

Calibration Values
0: Sensor is not calibrated
1: Sensor is partially calibrated
2: Sensor is partially calibrated
3: Sensor is fully calibrated
