The LCD when ‘idle’ displays Date and Time on the Line1 and Station Id on Line 2. Station Id is a 16-character string consisting of 16 alphanumeric characters without any spaces in between. The same string is used in audio record file naming. When display is ‘idle’ state, it displays the call progress messages on Line2 and returns to ‘Station Id’ display when there are no calls in progress. The other strings that are displayed for other call states are: "Calling ALL... " "ALL Disconnected" "Answered Gate x ", and "Gx Call Ended ".

There may be no device available or not a memory device with FAT file system. If a valid device is detected, it starts copying internal WAV files one by one to the device. The display shows these states. During successful copying of files, it shows the file numbers that are being copied to USB device. Once copying of all files is done it gives confirmation and asks to remove the USB device from the connector. If copying is interrupted by an incoming/outgoing call, the same will be informed to the user. Make sure that USB Pen drive is formatted with FAT file system and sufficient free memory is available for the copy of voice records.
