The device operates primarily in Trunked Mode Operation (TMO), utilizing the network infrastructure. The manual outlines the intuitive process for selecting talk groups via the rotary knob or programmable function keys. Individual calls (Private Calls) allow for one-to-one communication, while Group Calls facilitate efficient fleet-wide broadcasts.

A critical feature highlighted in the manual is DMO, or "Back-to-Back" mode. This allows units to communicate directly with one another without relying on base stations or infrastructure. This is vital for emergency scenarios where the network may be compromised or unavailable.

Security is paramount in TETRA networks. The manual outlines the procedures for activating Air Interface Encryption (AIE) and End-to-End Encryption. R4.0 enhances the key management logic, ensuring that encryption keys are updated seamlessly over the air (OTAR) without disrupting service.
