When setting the transceiver's baud rate, its RS232 data rate is set. The baud rate does not 
have to be the same setting for the two transceivers in the Point-to-Point network.

 are approved by the FCC for use in the 

United States.)

 

 

The 

Tx Frequency

Rx Frequency

 options, or Frequency Key, are located in the 

F

 

submenu after you press
