Retail Communications Technology: CST’s new ‘two-way radio plus’ package

Communications specialist enhances capacities of new Motorola SL4000

Call Systems Technology (CST) has launched a new system that integrates several different communications devices with the latest digital two-way radio technology. The result is a package that delivers what CST’s managing director, Eloise Sheppard, describes as a “highly effective and flexible communications solution,” because it combines the ease of use, reliability and portability of two-way radios with the functionality of pagers and call buttons.

The system incorporates the latest Motorola SL4000 two-way radio. This compact, slim and tough radio offers crystal-clear digital audio yet is half the weight and size of a standard radio. Its capabilities are greatly extended by linking it to CST’s Genesis communications software package, which allows full use of all the radio’s data-carrying potential. For example, managers and staff can send text messages to SL4000 radios directly from computers, while their screens can also display critical alarms monitored and reported to it by CST’s Genesis system.

“Integrating with other communication devices, via CST’s Genesis software system, greatly enhances the SL4000’s capabilities,” says Eloise Sheppard. “It creates a complete communications solution, improving a retail site’s safety, service and efficiency.”

The CST solution can also link the SL4000 directly to many other communications devices, such as lone worker alarms, personal alarms and wireless ‘Call’ buttons. For example, distributing call buttons around a retail store will allow customers or members of staff to send an immediate alert, or message, to the radio – at the touch of a button. Typical applications include cashier-desk panic buttons, assistance buttons in changing rooms and service buttons in aisles or at information points. The radio displays the location of the button that has been triggered, making it easy for staff to respond quickly.

Standard features include Bluetooth and intelligent audio, which adjusts to compensate for background noise. An option offers vibration for alerts. The SL4000’s safety features, which include a ‘covert’ mode that shields the display, LED lights and audible tones, make it suitable for security staff in sensitive environments.
