The  GME  Electrophone  TX4200  UHF 

transceiver  has  been  wholly  designed  and 

manufactured  in  Australia  by  Standard 

Communications  Pty.  Ltd  to  exceed  all  the 

requirements  of  the  UHF  CB  service,  while 

withstanding the forces of the harsh Australian 

and New Zealand environments.

The  TX4200  incorporates  the  very  latest  in 

CAD/CAM  (computer  aided  design,  computer 

aided manufacturing) techniques to produce a 

UHF  CB  transceiver  with  outstanding 

specifications and performance.

The  new TX4200  incorporates  amongst  other 

things,  a  liquid  crystal  display  and  fully 

programmable  scanning  .  In  addition,  the 

TX4200 has a number of innovative signalling 

features  including  fully  user  programmable 

Selcall  system  with  full  5  digit  received  Ident 

display, separate priority channel programming 

and a group call feature. 

Remarkably, with all these features the TX4200 

remains a very compact unit. 

FEATURES

•      Microprocessor  Controlled  Frequency 

Synthesiser: 

Allows  user  programmable 

control  of  scanning  and  channel  memory 

storage.

•    Non volatile EEPROM memory:

 All  dealer 

and  user  settings  are  stored  inside  an 

EEPROM.

•      User  Programmable  multi-tone  Selcall 

Function:

 CCIR tone compatible and built-in 

to the TX4200 microprocessor. 

•   SELCALL 'QUIET' mode programmable on 

individual channels:

 Allows mixed monitoring 

and scanning of QUIET and OPEN channel 

combinations  with  audible  alarm  when 

called.

•   T h r e e   S E L C A L L   m e m o r i e s :

  User 

programmable  storage  of  three  frequently 

called SELCALL Idents.

•   Open  Scan  and  Group  Scan  modes: 

The 

original GME scan functions are now even 

better,  fully  programmable  and  faster  than 

ever.

•    Liquid  Crystal  Display:

  Fully  detailed  LCD 

provides  a  visual  indication  of  all  selected 

functions at a glance.

•   High Contrast Backlighting:

 Not just the LCD 

but  all  rotary  controls  are  fully  backlit  for 

hassle free operation at night.

•    Individually  Programmable  Duplex  Function: 

User  selectable  for  only  those  individual 

channels in your area that have repeaters, 

leaving  the  others  free  for  use  as  extra 

simplex channels.

•  Digital  Signal  Strength  Meter:

  An 

improvement on the old 5 segment bar type 

meter,  the  digital  signal  strength  meter 

provides  a  numeric  signal  strength 

indication in numbers from 0 to 9.

•    Low  Profile  Microphone  Plug:

  The    'new 

generation'  low  profile  microphone  plug  

provides a stronger attachment and a more 

compact appearance.

•   Surface Mount Microchip Technology:

 Only 

the very latest techniques in surface mount 

component selection, assembly and quality 

assurance are used to ensure the highest 

quality  and  reliability  is  achieved  and 

maintained.

•    Designed  and  Manufactured  in  Australia: 

The  TX4200  is  totally  designed  and 

manufactured in our factory at Gladesville, 

NSW to meet the demanding needs of the 

Australian and New Zealand communities.
