WAV File Audio Messages
The C2N-IIF is capable of playing audio messages as system prompts
and responses. These files are recorded as WAV files on a PC using an
audio utility such as Sound Recorder that is packaged with Microsoft
Windows 95/98/Me/XP/NT/ 2000™. Files from other sources may also
be converted to an acceptable format by using this or a similar utility.
Many other audio utilities are available commercially or as shareware.
The C2N-IIF only accepts the following WAV file format: PCM, 8 KHz,
mono, 8 bit.
The C2N-IIF can store up to 30 WAV files. The total length of all WAV
files cannot exceed 30 seconds. For more information about how to use
Sound Recorder, refer to its User’s Guide and extensive help information
provided with the software.
