The security codes on radios in a hop must be matched, otherwise the two radios will not recognize
one another and will not communicate. The security code can protect the unit against one that is
not of the same security code by not communicating with that radio. Different codes can be
selected using the SW2 DIP switch segments 1 through 8 located on the Lynx.HD, 8xE1 rear panel.
The security code must be the same for both ends of a radio
link.
The factory setting for security code DIP switches is down (0). Should the code need to be
changed, then both ends of the link must be changed and set identically. Changing the security
code is an out-of-service adjustment. See Figure 3-15C for DIP switch segment settings. When
security switches on the two radios are not matched, AIS alarm on the front panel would be flashing
and the E1 data will be muted.
