13. Encryption code setting (D-CR & NXDN only)

These standards exist in both unencrypted and encrypted modes, although there are

only 32767 different encryption codes, from 00001 to 32767.

If you know the encryption code, it is possible to set this code into ARD300 to allow

decoding of the encrypted Digital CR and NXDN signals (limited to the 15-bit digital

scrambling type).

Note: In case of a non-encrypted transmission, ARD300 will simply decode it, no matter

what code you have set.

When the received signal is unencrypted, the LCD will display “D-CR” or “NXDN”,

When encrypted D-CR is received, the LCD will display “D-CR E”. Nevertheless in case

of NXDN, the LCD will always display NXDN whether the signal is encrypted or not.

ARD300 can only decode these encrypted digitals signal if you have set the correct

encryption code.

How to manually set the encryption code:

① Press the ENTER key for 2 seconds. The currently set 5 digit encryption code will

appear as follows:

The arrow represents the cursor

location.

② With the ▲ and ▼ keys, move the cursor to the desired digit.

③ Press ENTER to select that digit.

The arrow will change to a star.

④ Change the value of that digit by using

the ▲ and ▼ keys.
