The new Caltta PH6 series are part of the DMR Tier 2 portfolio which support DMO, conventional transition, IP connection and trunking mode to provide full ranges of features such as recording, location, Bluetooth, and man down alarm...etc. To be more specific, PH690 is equipped with the 2-inch half-transparent color screen and full keyboard; the more compact PH660 is equipped with the 1.74-inch half-transparent color screen; PH600 has no screen but highly optimized the audio and voice broadcasting. The diverse terminals can support different application scenarios and requirements. More than that, the PH6 series support IP68 protection, robust enough to operate in a variety of harsh environments.

With only 1U height, the new generation repeater PR900 is optimal to stack and to support various networking scenarios such as IP connection (up to 64 sites), Enhanced Conventional System (ECS ), and simulcast function. According to the on-site staffs, not only for a larger coverage and increased communications range, PR900 also features the ECS and extended channel capacity, making it an ideal choice for airports, seaports and large factories demanding a higher level production safety, reliability and capacity during operation and dispatching. Its ingenuity industrial design and powerful service functions are widely appreciated by the partners and visitors.
