VX-450 Series industrial portable radio features
Monitor Worker Safety
Like all Vertex Standard equipment, the VX-450 series includes built-in Emergency and Isolated Worker alerts. Emergency notification is user-initiated with a press of a button for the radio to switch to a designated channel and send an alert for help. Isolated Worker mode is a built-in timer that requires the user to reset at a predetermined interval. If not reset, the radio automatically switches to Emergency mode to alert help.
When constant contact is required at all times, Vertex Standard’s exclusive Auto-Range Transpond System (ARTS™) is included to inform the user that other ARTS™- equipped radios are within communication range.
No two work zones are the same, so the optional fall warning function (with DVS-9 unit) can be programmed to control a wide variety of safety scenarios, including the degree of vertical and horitzontal angle of the worker, as well as the degree of motion or inactivity. By adjusting the parameters of the 3-axis sensor,the equipment adapts to each working environment to control movement.
Solid Build for Extreme Environments
The VX-450 Series meets military resistance standards for ruggedness and the IP57 waterproofing standard protection, so water will not damage the radio if it is immersed at a depth of 1 meter for up to 30 minutes.
Infallible Audio and Voice Response
It has an audio output of 700 mW, ideal for noisy working environments.
Includes a multilingual Channel Announcement, which clearly explains the channel description to simplify channel switching.You can also record your own ads to make browsing easier.
Features Voice Activation (VOX) when used with MH-81A4B headset, which allows users to transmit voice without pressing the Push To Talk button for hands-free operation.
Record and store up to 120 seconds of voice messages using the optional DVS-8 Voice Storage unit.
Built-in Selective Signaling Modes for Greater Flexibility
Includes MDC-1200® encode/decode along with DTMF, 2-tone and 5-tone encode/decode to provide selective radio calling and efficiency in responding to a wide range of communications needs.
Easy-to-manage group communications
Both the VX-459 and VX-454 radios have a massive 512-channel capacity and 32 groups to easily handle a wide variety of calls in the most complex work environments.
The VX-459 also includes Direct Channel Retrieval for access to the desired channel from the keypad.
