ASTRO Digital XTS 5000 Model III 77
Special Radio Features
Secure Operations
Secure radio operation provides the highest commercially available
level of voice security on both trunked and conventional channels.
Unlike other forms of security, Motorola digital encryption provides
signaling that makes it virtually impossible for others to decode any
part of an encrypted message.
Note: Secure operation is not available in trunked analog modes.
