Troubleshooting – Blank Information Display

If the front panel 4-line LCD Information Display is blank:

 

As long as input power is applied (as indicated by the power light being green and the LED time display incrementing) the 4-line LCD Information Display is capable of displaying data. The Information Display can be configured to display different data while the keypad is not in use. One available configuration is to have the Information Display show a blank page when not in use. The Information Display operation can be verified and can also be configured via the Web UI, or the front panel keypad.

  1. Using the front panel keypad to verify the LCD Information Display is configured to display a blank page:

    To verify the front panel LCD Information Display is configured to display a blank page, just press any keypad button. As long as the keypad is unlocked, the Home screen will be displayed (after one minute of not pushing any keys, the screen will go back to blank).

Note: The information that is selected, is the page that is normally displayed in the LCD window, beginning one minute after the keypad is no longer being used.

  1. Using the front panel keypad to change the information normally displayed in the LCD when the keypad is not in use:

    To use the front panel keypad to reconfigure the LCD Information Display to show something other than a blank page (such as GNSS information, network configuration, etc.), see Front Panel Keypad, and Display.

  2. Using the Web UI to change the information normally displayed in the LCD Information Display when the keypad is not in use:

    To use the Web UI to reconfigure the LCD Information Display to show something other than a blank page (such as GNSS information, network configuration, etc.), refer to Configuring the Front Panel.
