Loading Custom Sounds

You can load up to 25 custom sounds, saved as WAV files, to the O3. Each sound file should not exceed 1 MB. The total number and size of custom sounds supported will depend on the amount of remaining free space in the system.

To load custom sounds to the O3:

1. Create a FIL object for each audio file, with instances between 126 and 150.
2. Open each FIL object and upload the audio file that you want to associate with that FIL.
3. Update the existing MIC2 object and add states 26 to xx for the custom sounds (FIL126 to FIL1xx).

To play a sound, command object MV28 (Play Sound) to manual mode and set the object value to the sound you want to play. For example, "1. Power On".

Enabling a Startup Sound

You can enable the "Power On" startup sound to play when the O3 is restarted. By default, this option is disabled.

To enable the startup sound:

1. Command object BV44 (Startup Sound Enable) to manual mode and set the object value to On.
2. Restart the O3 to verify that the sound plays. If you're using enteliWEB, on the object list page, click Device Actions > Reset.
