## Device Functionalities

For more digits of data, such as historical data and long-term cumulative data, please see the LCD.

LCD monitor allows display for 16 English characters in 3 rows . The first row is current content with units. The second row is data. The third row is a definition of each button.

The LCD screen has a 3-color backlit display. Definition of each color light as below:

1. Geen: Real-time data, device is working normally.
2. Red:
   1. Blinking red light: Alarm A- Major error. Please see the “[Alarm and Description of System Conditions](broken://pages/-M7fju8G25dJVL-1tSmD#alarm-a-major-abnormality)” page for more details.
   2. Continuous red light: Alarm B- Current status of the device meets the parameters set-up by the user so must pay attention to it. Alarm C- The calendar battery needs to be replaced.
3. Orange: Non real-time data display. Historical data query and set-up page display.

There are 4 buttons on the device, the definition of each button will be displayed at the upper row on the LCD screen. Generally, the leftmost button stands for “Exit” or “Back to last page”. The middle 2 buttons are for users to review page by page, modify data, or switch option. The rightmost button stands for “Set” or “Confirm”. Previously mentioned definitions are only for general use. For some other use scenarios, button definitions are modifiable for usability or error proof.
