The TX4200 is provided with a wide variety of 

programmable  functions.  During  the 

development of the TX4200, extensive research 

was  conducted  to  identify  specific  user 

requirements  and  shortfalls  in  current  UHF 

transceiver  technology.  The  result  is  a 

transceiver that can be optioned to meet a wide 

range of applications and personal tastes.

 Many of these options can be selected directly 

by using the TX4200’s controls. However, some 

options  can  only  be  set  using  an  external 

programmer.

The  following  is  a  list  of  available  options 

indicating which are user selectable and which 

are  dealer  programmable.  The  initial  factory 

settings  are  also  indicated.  Below  the  list  are 

descriptions of how to use those options which 

are not factory defaults (operation of the factory 

default  options  are  already  described  in  this 

manual).
