GD-37
NOTES:
Do not connect or disconnect the USB memory while the GD-37 is running, irreparable damage may occur to the USB memory or to
the GD-37 itself.
Do not connect or disconnect the SD card with the GD-37 running, irreparable damage may occur to the SD card or to the GD-37
itself.
For the correct operation of the GD-37, it is essential that the audio directories on the SD card contain at least one correct file, that is,
a “.mp3” file in the “MUSIC” folder, a “.wav” file. in the “VOICE” folder and a “.wav” file in the “SOUND” folder.
It is necessary to turn off the GD-37 before inserting a USB memory; When the equipment is turned on again, the memory content
will be analyzed and when the GD-37 detects music files, these will be selected to be played whenever the user wishes.
While the GD-37 is playing Music from a USB memory placed on the front of the equipment, the Music content present on the SD
card connected on the back will not be available.
The file system used by the GD-37, to save the information in the SDCARD and USB memory units, does not support the name of
files of more than 8 characters, so it is required that the name of the files, .WAV , .MP3, and .BIN, be limited to 8 characters as the file
name and the typical 3 characters for the extension, plus the separation period. Additionally, the GD-37 supports the use of the ID3
tag related to the song name in all .MP3 files, in order to display long names on the computer screen.

IMPORTANT NOTE:
The PLAY / PAUSE shortcut key affects only the playback of background music, while the STOP key additionally affects
externally triggered messages (remote controls), those triggered by calendar events, etc.

indication implies the opening of the FAULT contact located on the rear side of the GD-37.
3. Music ON

On the front of the GD-37 there are two direct access keys to music playback (PLAY / PAUSE and STOP). To play the audio files
stored in the SD card or in the USB device, it is not necessary to connect the PC to the GD-37. By manipulating the PLAY / PAUSE
keys and the STOP key, you can start, pause and stop the playback of the music files on the SD card. In the case of having a USB
device connected, the audio files on the USB device will be the ones that can start, pause, and stop playback.
