Setting Acoustic Parameters
 The ST automatic handsfree mode works as follows: if there is silence on both
sides, the sound channel is muted; if a threshold sound level is exceeded, the
loudspeaker or the microphone goes on depending on which party starts
talking, or is talking more loudly.
 The optimum acoustic parameters are set by default. You are not
recommended to change them unless under exceptional circumstances. For a
change, use parameters 931 through 938.
Switch programming
 Each of the 3 switches has its predefined password (00, 11 and 22) according
to the table. If you use a new password, do not forget to remove the old one
 Up to 10 various passwords can be programmed for each switch. Thanks to it,
different persons can use different passwords and all you have to do to “block”
one person later , is to remove the person‘s password and keep the other
passwords valid.
 All passwords are checked during programming, i.e. it is forbidden to enter
one password twice.
 If you wish to use a faster switch control method (a password without ), be
careful while entering passwords of variable lengths: if a shorter password is
identical with the beginning of a longer one, you cannot control the switch with
the longer one. Moreover, if you use Automatic dialing with confirmation, your
passwords may not start with 1 to 5.
