@gramdale: First of all, welcome. You'll find plenty of helpful people here.
This particular topic is about the Witstech A81/A81E aka W1060. I didn't check but there may be an area for Sungale devices. You can find a user manual for the CD700A at
http://www.myalphadigital.com/down/m...700A-UM-EN.pdf in case you didn't get one from your friend. It indicates you just load the txt file and then browse to it with the reading app built into the device (page 16). I don't have the device so I'm not much more help beyond that, sorry.
