operation
× Activating the scrambler
The optional voice scrambler provides private communica-
tions. In order to receive or send scrambled transmissions,
you must first activate the scrambler function. To activate the
function, either an optional UT-98 or UT-112 is necessary. Ask
your dealer for details.

×Programming scramble codes
There are 128 codes (00 to 127) available with UT-98 or 32
codes
(01 to 32) available with UT-112 for programming. In order
to understand one another, all transceivers in your group must
have the same scramble code, as well as the same scrambler
unit. See page 19 for scrambling code setting details.
RECOMMENDATION: Use the optional speaker-micro-
phone during voice scrambling operation for much clearer
audio readability.
