CB or commercial frequency modes

The VX-456 CB radio provides both CB and commercial frequency modes, allowing you to choose the best option for your usage.

Extended Signalling and Security Capabilities

The VX-4600 CB provides a full range of signalling capabilities including 2-tone, 5-tone and MDC 1200® encode/decode for selective calling. With the built-in voice inversion encryption, private communication is enhanced, ensuring messages could only be heard by those intended.

Enhanced Audio Performance

Channel Announcement function works to simplify your chore of switching from the current channel to other channels while task on hand. Equipped with Voice Activation (VOX) to enable users to transmit voice without pressing the hands-free operation for convenience. Suitable for noisy environment, where the Clear Voice function can be activated to ensure your message is heard. Suitable for quiet environment, where the Whisper capability function can be activated to augment audio transmit, perfect for much needed discreet communications.
Equipped with the DVS-8 Voice Storage unit, which enables you to record and store up to 120 seconds of important messages.

Monitoring Worker Safety

The VX-4600 CB, as with all the Vertex Standard radios, has key features to ensure the safety of the user.

Built-in Emergency Alert - Equipped with the built-in Emergency notification function, which will switch to a designated channel, send an emergency unit ID and transmit with a live microphone, an added benefit when working alone.

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

Vertex Standard’s exclusive Auto-Range Transpond System - ARTS™

A function that keeps the user within communication range with other ARTS™- equipped radios, so constant contact is at its optimal.

Manageable System for Large Group Communications

Opt for the VX-4600 series with 512-channel capacity and 32 groups for easy operations. Efficiency is maximised.

Remote head option

The RMK-4600 remote mount kit is available as an option. This provides flexibility in mounting the mobile radio in restricted spaces. The control head (face plate) can be mounted on the dashboard whilst the radio can be situated elsewhere in the vehicle.

Option board connectivity

Optional DVS-8 Voice Storage Option Board and DVS-9 Man Down option board provide value added features to the customers.

Remote mount option

If there is limited space, this radio has the added benefit of a remote mounted faceplate. Mount the faceplate in the dashboard and the main radio elsewhere; concealed under a seat or behind the driver in the cab of a truck, with no impact to your communications. The optional remote mount kit comes complete with a five metre ribbon cable with waterproof connectors.
