Expanded Signalling and Security
Both radios provide a full range of signalling capabilities including DTMF, 2-tone, 5-tone and MDC 1200® encode/decode for selective calling.

Private communication is supported by built-in voice inversion encryption. And, if a radio is ever lost or stolen, 5-tone remote stun/kill/revive can be activated to ensure messages are only heard by those intended.

Enhanced Audio Performance
These radios feature Channel Announcement, which loudly speaks the current channel description to simplify changing channels when focused on other tasks simultaneously.

Also included is Voice Activation (VOX) that enables users to transmit voice without pressing the Push to Talk button on the microphone. Enables hands-free operation for convenience.

In noisy environments, activate the Clear Voice function to enhance audio transmit to ensure your message is heard. And, to ensure a radio is not accidentally turned down too low, a minimum volume limit can be programmed by your Dealer.

Whisper capability is also included to augment audio transmit when talking quietly is necessary for discrete communications.

Record and store up to 120 seconds of voice messages for keeping an audible record of important communications using the optional DVS-8 Voice Storage unit.

When Safety Counts
As with all Motorola VX and EVX Series mobile radios, the VX-4500/4600 Series includes Emergency Alert for enhanced driver safety.

Operators can activate the Lone Worker function when leaving equipment or a vehicle temporarily. If a problem arises while away, the radio switches to Emergency mode to alert help.

When constant contact is required at all times, Motorola’s VX and EVX Series exclusive Auto-Range Transpond System (ARTS™) is also included to inform the user that other ARTS™-equipped radios are within communication range.
