The LC display of Meteo-42 with background light is able to show 4 lines, each with 20 characters. In order to navigate through the menu or to perform an action, use the buttons next to the display.

Figure 9.1. Use of the Meteo-42 buttons

Press this button for a few seconds to switch Meteo-42 (CECS) on or off.
Navigate into a submenu or perform an action.
Scroll down in the menu list.
Leave the submenu, return to the previous menu.
Scroll up in the menu list.

	Note
	After connecting Meteo-42 to the power supply, the two lower LED lights (red and yellow) turn on for a few seconds. When the LED lights turn off, Meteo-42 is ready and can be switched on.

9.1. Assigning Permissions to Display Users

In order to avoid that settings are accidentally modified by a display user, e.g. when measurement data is downloaded on a USB flash drive, you can assign permissions to display users. The configuration can be changed in the System → Display menu (see also Section 4.5.1, “Display Access”).

9.2. LED Lights

Meteo-42 has four LED lights next to its display. The two upper LED lights have not yet been assigned a function. The two lower LED lights (red and yellow) turn on, when Meteo-42 is connected to a power supply and turn off as soon as Meteo-42 is ready to be switched on. However, the lower LED lights show:

Red (third from the top): Indicates errors in measuring operation. For details see the error list in the display System → Errors → Error List.
Yellow (lower LED light): Indicates that RS-485 sensors are connected. According to the Modbus protocol the LED light blinks, when a measurement is made.

9.3. Navigating through the Display Menu

The display menu of Meteo-42 includes four main menu items and several submenu items. The main menu items are System, Status, Channel and Communication.

In order to jump into a submenu or to perform an action, press the right button. To return to the previous menu, use the left button. By pressing the upper or the lower button, you can navigate up and down the menu list. For further details see Figure 9.1, “Use of the Meteo-42 buttons”.

Some menu items allow you to reconfigure the system, e.g. Communication → Devices → LAN → eth0 → Method, which lets you change the connection method of the Ethernet port. Pressing right changes the ">" symbol to ">>". You can press up and down to change the value, and left to confirm the change. The changes will only be saved if the display has the relevant permissions (see Section 9.1, “Assigning Permissions to Display Users”).
