We would like to introduce a case study of the implementation of the portable digital simple radio "SR810UA" for our customers in the security industry. The security base shares its facilities with other companies, and there are numerous radios operating within the area, indicating room for improvement in the management system of the radios. Additionally, while multiple teams required radios, there was a desire to reduce the number of units as much as possible. After implementation, we were able to consolidate communications into one unit, allowing us to equip multiple teams with radios while reducing the overall number of units. Furthermore, the management of radios within the security base became simpler than before implementation, leading to operational improvements. 【Case Overview】 ■ Challenges - Each team was using two radios for internal communication and two for overall communication. - There was a need to reduce costs associated with radios. ■ Implementation Results - Operations became possible with just one radio. - Cost savings were achieved through a reduction in the number of radios. *For more details, please download the PDF or feel free to contact us.
