Scramble Seed
Press this softkey to make scramble seed the active function. Scramble
seed specifies the scramble starting point in the PRBS generator. Enter
values in hexadecimal.
In the TETRA format, the 32-bit scramble seed comprises four fields.
The two least significant bits are defined by the TETRA format as 1
(but you must input them anyway). The remaining 30 bits are the
extended color code that is divided into three fields:
• mobile country code
• mobile network code
• color code
The two least-significant bits are appended to the color code, so if, for
example, you set a color code of 1, a scramble seed of 7 is required.

softkey.
