You must follow the procedures as below step-by-step. 
(1) Power off TA.  
(2) Check the RS232 cable is connected with PC well. 
(3) Change the Terminal program to 38400 baud, 8N1, CTS/RTS hardware flow control. 
(4) Entering the terminal mode again. 
(5) Power on TA again, you will see the screen display: 
“ Erase and reprogramming flash EPROM contents (y/n) ? 
 
(6) Enter “y” and follow the steps from 8.1 (6) as stated above.  Then you can still  
   finish the re-flash procedure.  And you will see “38400, 8, N, 1” instead of  
   “115200, 8, N, 1”.  Due to the baud rate is slower therefore it takes about 10  
   minutes to finish re-flash.
