HF-90 Operation & Installation Guide 

At this point your display will appear as follows:- 

Several seconds after pressing the STAR key to send the 
Telcall, you should hear a series of high pitched beeps.  This 
is the Telcall Confirmation being transmitted from the 
Telephone Interconnect Station to let you know that your 
Telcall has been received successfully.  If you do not hear the 
Telcall Confirmation you should repeat the procedure 
outlined above, on the same channel or a new channel.  If 
your Selcall is not successful this may be due to inappropriate 
frequency selection or excessive interference (refer to Section 
2.3 of this Guide).   
 
If your Telcall is successful (ie. you hear the Telcall 
Confirmation) you will hear the telephone ring at the other 
end.  This will take several seconds as the Telephone 
Interconnect Unit has to complete its dialling.  After the 
person at the other end picks up the telephone, you will 
generally have to wait for a start tone before proceeding with 
your call. 
 

Please note that communications will be in simplex mode (HF 
radio mode) therefore you should inform the telephone user that 
you are calling from an HF radio and that all speech should be 
ended with the word “OVER”. 

 
If the telephone at the other end is not picked up try again 
later. 
 

If your Telcall is successful and you have managed to get 
through to the telephone user, you should complete the call 
(ie. hang up) by pressing the HASH key twice.
