Alternatively, the system can generate a random
128-bit (32 hex characters) encryption key for you.
To do this, click the “Calculate 128-bit full key”
button (refer to Figure 14.4).

Step 4 – Upload a new encryption key
After a key has been generated it must be uploaded
into the system. Not only the
WCAP , but also all
wireless delegate units that need to connect with the
WCAP must know the same key.
Upload the key by clicking the “Upload key” (refer to
Figure 14.4)
Step 5 – Activating the new encryption key
The WCAP will start encrypting the transmitted data
and audio after a custom key has been selected.
Figure 14.5: Custom key selection
If the WCAP needs to use the selected key next time
it powers up, push the button.
Caution:
Wireless units not containing the same
encryption key as selected, because they
were not connected with the WCAP at
the time of upload, can no longer
connect with the same WCAP.
The units will be ignored by the system!
Caution:
Only the units that are connected with
the WCAP can receive the newly
generated encryption key.
Other units will be ignored!
Note:
During the upload, the microphone LEDs
will flash.
Once the upload is successful, the LEDs
go out.
Caution:
Only use hexadecimal characters i.e.
choose 32 characters from the
following list:
0, 1, 2, 3, 4, 5, 6, 7, 8, 9, a, b, c, d, e, f.
If a key shorter than 32 characters has
been entered, then the remaining
positions will be filled with zeros.
If a key longer than 32 characters has
been entered, then the key will be
truncated after the first 32 characters.
