When a unit in scrambled mode calls another unit, the called unit’s handset will detect synchronization and if the 
unit is not in secure mode it will automatically switch to scramble mode and descramble the incoming audio. The 
unit will remain in scramble mode so that it can talk back and forth and carry on a secure conversation.  

The unit that has been called is now in secure mode and if the unit needs to return to clear mode, simply turn the 
power off and then back on. 

If a unit is in scramble mode already, and a clear call is transmitted from a 

non-scrambled

 handset, the unit will 

remain in scramble mode, because it did not see a sync packet with a command to go to scramble or clear and 
cannot  understand  the  clear  transmission  from  a  regular,  non-scrambled  handset.  In  this  case  it  would  be 
necessary to flip  the power off and then back on so that  the TVS-2V-HS1 handset comes up in the clear  mode 
(indicated by 3 beeps). 

The scrambler in the handset receives audio from the earpiece pin on the manpack radio connector. It receives 
synchronization  information  and  scramble/clear  audio  via  this  pin.  Therefore,  the  audio  level  cannot  be  turned 
down so low that nothing is presented to the earpiece pin. On the PRC type radio, keep the volume control set to 
a high enough level to receive and decode synchronization. This minimum level is generally 1/2 way between the 
second  and  third  dot  on  the  volume  control.  Above  the  ninth  dot,  the  radio  tends  to  generate  distortion  and  the 
audio presented to the ear becomes painful. The most comfortable level seems to be between the minimum level 
and 5

th

 dot.
