Chapter 3: Operation
42 AVIATOR Wireless Handset functions
Upon successful key negotiation and peer
authentication, you hear an audio signal
in the AVIATOR Wireless Handset to
inform you that a Short Authentication
String (SAS) is shown in the display. This
string consists of a combination of 4
digits and characters (symbols).
3. You must verify the string. Compare your
own string with the peer string.
Example:
Say the first 2 symbols and the
peer (i.e. the person called) says the last 2
symbols.
If the comparison of the SAS is ok, press
Yes.
4. The line is secure and the display shows
Secure and a Padlock. Voice streaming is
encrypted and decrypted.
Note
If the 4-digit SAS is not
identical , press No when asked
to confirm SAS authentication.
The secure session is aborted
and the call is terminated.
Note The AVIATOR Wireless Handset
supports one secure call at a time.
If there is a secure call established
and put on hold, you cannot
establish another secure call.
