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.
