LCD Programming

For most installations, the default settings in the GT1524 do not need to be changed; the system can be used as soon as power is applied. However, if you need to customize any settings, such as telephone connection options or input parameters, you can do so through the front panel user interface.

The front panel includes a 2x16 character LCD, menu buttons, and LED bar meter. When power is applied to the GT1524, all LEDs light and the LCD panel reads INITIALIZING. If initialization is completed without errors, a title screen appears, showing the product name (top line) and the version number (bottom line). The title screen remains on display until you initiate some action that writes information to the LCD panel or the GT1524 detects and displays an error. If an error is displayed, contact ClearOne Technical Support.

2.4). Enter each of the trees by pressing the up/down buttons and scrolling to the
