My Own Files

You can load your own audio files onto the CF-Card and replay with the
NTi Audio TalkBox. Kindly observe the following details:

Do not delete the calibration data file labeled “xxx.cal“!

The NTi Audio TalkBox requires the calibration data to meet the product specifica-
tions. A back up copy of the calibration data is on the NTi Audio TalkBox CD en-
closed, containing the original data of the CF-Card.

The first character of the wav-file name matches the

Box selection switch position and “anyName” describes the content of the wav-file
for example “9_myfile1.wav” or “A_myfile2.wav” - “F_myfile3.wav”. The maximum
length of the filename (=anyName) are 8 digits.

The test signal level shall be physically tested by using an NTi Audio Acoustic Ana-
lyzer and the source data adjusted to requirements.
