FN-BC10 FAQ
Q1: I changed the configuration file to a new trigger mode. The default trigger mode is still used, instead of the new trigger mode.
A1: Make sure your computer is not set to hide the file extensions. Your file is incorrectly named "read.cfg.txt" instead of "read.cfg". Uncheck "Hide extensions for known file types" under "folder options" and rename your config file to "read.cfg"
Q2: When I apply power to the module, WITH the microSD card already inserted, the configuration file (read.cfg) stored in the onboard flash memory is used, instead of the read.cfg file on the microSD card.
A2: Take the onboard read.cfg file offline by renaming it to a different name. Now the read.cfg file on the microSD card takes precedence and sets the correct mode. If it still doesn't work, put your read.cfg file on the onboard flash memory instead of the microSD card.
Q3: How do I adjust the volume of the board?
A3: All you need is a small star point screwdriver. The onboard potentiometer used to adjust the volume is the small blue square just next to the headphone jack. Turn clockwise to increase volume. Turn anticlockwise to decrease volume. This potentiometer only controls the onboard amplifier. It does not control the 3.5mm audio jack volume.
Q4: Is the square potentiometer able to be used to adjust the volume for the audio output from the headphone
jack as well?
A4: No, the headphone jack gives an audio signal only to an external amplifier/active speaker/headphone. The volume adjustment relies on connected devices.
Q5: What bitrate must the MP3 file be?
A5: The module supports bit rates of 32 Kbps, 64 Kbps, 96 Kbps, 128 Kbps, 256 Kbps, and 320Kbps for MP3 files. Other bit rates for MP3 files could cause problems with playback.
Q6: What sampling rate must the .wav file be?
A6: The module supports sampling rates of 8 / 11.025 / 12 / 16 / 22.05 / 24 / 32 / 44.1 or 48 KHz for .WAV files. Other sample rates for .WAV files could cause problems with playback.
Q7: My computer isn't recognizing the board when I plug it into my computer
A7: Some micro USB cords can only transport power through them, so it is important to make sure the cable can transfer both power and data. In other words, some cables are only good to charge devices, but cannot communicate with them. The first thing to do is test if the cable can not only charge but also communicate with other devices such as a phone, if not try a different cable.
Q8: The .wav file has an audible "click" when finished playing on the module. However, there is no "click" when I listen to the file on my computer.
A8: We converted the frequency of the files from 22.05KHz to 44.1kHz and the "click" disappeared. The "click" also disappeared when we converted the files from .wav to .mp3 format.
Q9: The sound files that I put onto my device won't play when using an Apple Mac to put the sounds onto the device. Or some of the buttons don't work.
A9: We found that some versions of the MacBook create some hidden junk files when used to copy to the microSD card or onboard flash memory. These hidden files causes the sound module to malfunction. The solution is to reformat the microSD card or onboard flash memory, using a Windows computer and then copy the sound files to the microSD card or onboard flash memory using a Windows computer. If you don't have a Windows computer available, please see this link that a customer wrote up about a past sound module that he had, and that he used the same information to get our sound module to work. Here Is a link to the article as well as the software that he mentions:

Q10: Uploaded my sound files to the unit, but one or more button doesn't work.
A10: Convert your sound files from WAV to MP3 or vice versa. Then re-upload the sound files to the sound module. If that doesn't solve the issue, change the sample rate of your sound file to a different sample rate and then upload the new sound file back to the sound module.
Q11: I have multiple sound files on a button. I want them to playback sequentially instead of random sequence.
A11: Unfortunately this unit only allow for random playback when more than a single file on a button. The FN-AL6T instead can playback files in sequence in the folder for each button when a number "5" in the config file.
