S-registers are sections of memory in which values are stored that affect how the TA operates. S-registers
are so-called because each has a name that begins with the character S. Use the 

Sr=n command to

assign a value to an S-register or use the 

Sr? command to read the current value of an S-register. S-

registers are stored in non-volatile RAM (NVRAM) by using the 

&W0 command. ATZ<CR> restores S-

registers to values stored in NVRAM if any were stored using the 

&W0 command, otherwise they revert to

factory default settings in ROM. Table 4-2 summarizes the available S-registers and their function.

See the additional documents on this CD for more information on each S register.
