The CARRY-CODER II offers the choice of encrypting the transmitted signal in order to ensure the privacy of the link.  This feature 
is controlled through the following menu: 
 

ENCRYPTION 
OFF  ENTER PIN

 

 
This operation uses a 6 digit encryption code. Both the transmitter and the receiver must have the same PIN encryption code in 
memory.  If not, the DC II receiver will indicate <BAD ENCRYPTION>.  The receiver will demodulate the signal, but it will not provide 
valid audio, video or data outputs.  Once an encryption code is stored, the operator cannot read the setting of the code: if the code is 
not on record, the operator must change to a new encryption code or set Encryption to < OFF >.   
 
To activate signal encryption, the operator selects this menu function then presses < OK > to enter the Menu Edit mode.  Move the 
cursor to ENTER PIN.  Press < OK >.  The digits available for the CARRY-CODER II encryption code are 0-9, and A-F.   
 
 

 

The PIN code is only visible when you enter it.  If you forget the PIN code of one device, the simplest solution is to 
enter a new PIN code for both the transmitter and the receiver. All six digits set to < 0 > result in no encryption. 

 
The (first generation) CARRY-CODER I (CC I) and the DE-CODER I (DC I) receiver use four digit PIN encryption of 0-9.  When the 
CARRY-CODER II transmitter is used with the DE-CODER I receiver, the CARRY-CODER II encryption is compatible if the PIN 
encryption setting has the first two PIN digits set to <0> (i.e., PIN setting <001234> on the CC II or DC II will work with PIN setting 
<1234> on the CC I or the DC I>.   Any letters used in a CCII encryption code will be interpreted as 0 by the CCI or DCI systems.
