Number of Codes:
The VS-1150-SM1G can have up to 4 codes programmed into the unit. The codes can be
programmed for any of the 32 double inversion split points shown on page 20.
Power Up In Scramble Mode:
If selected the unit will start up in secure mode when the power is turned on. If it is
desired to have the unit always in secure mode, then check this box and do not assign a button for mode select.
TX Pre/De-emphasis Enable:
This setting controls the use of audio emphasis by the scrambler while
transmitting. If checked, the scrambler will perform pre-emphasis before scrambling and de-emphasis after
scrambling. If the radio performs pre-emphasis of TX audio after the scrambler insertion point, this box should be
checked. If this information is not known, choose the option that yields the best recovered audio quality. See the
diagram on page 20.
RX Pre/De-emphasis Enable:
This setting controls the use of audio emphasis by the scrambler while
receiving. If checked, the scrambler will perform pre-emphasis before de-scrambling and de-emphasis after de-
scrambling. If the radio performs de-emphasis of RX audio before the scrambler insertion point, this box should
be checked. If this information is not known, choose the option that yields the best recovered audio quality. See
the diagram on page 20.
