1-13-94                   VFDI Voice Quality

     To  get  the best voice quality with the Internal  Voice/faxmodem,  in

Bitfax go to SETUP, then VOICE and set Baud Rate to 38,400 and Bit Sampling

to 3. The defaults are 19,200, 2 bits for externals (which cannot support 3

bits through the serial port). This will use about 1/3 more disk space per

message.  Also the Windows comport driver cannot handle over 19,200. If  you

are using Windows, get a new driver like Turbocom.

     If  messages get cut in the middle, increase the Silence Threshold  in

voice setup.

      Unfortunately  because  of the limitations of a serial port  and  the

2400  Voice/faxmodem, you cannot set the paramters to get the best  quality

with the external Voice/faxmodem and it may sound a bit scratchy.

     (note: The 14,400 externals with Bitfax do support 38,400, 3 bit)
