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.
