To transmit and receive messages:
Cryptographic variables (FILL keys) must be loaded into the radio using a compatible Data Transfer Device (DTD) or key loader. Without these synchronized keys, radios cannot decrypt voice data or follow the frequency-hopping pattern. Channelization Without these synchronized keys, radios cannot decrypt voice
: Features fast link set-up (approx. 5 seconds for the first frequency) to automatically find the best available channel.
The unit is designed to withstand extreme temperatures, but check seals to maintain water and dust resistance. Conclusion
