Caltta DH400/410/460 radios bring versatile and practical voice call features to the staff and the best value for money to business owners.

Caltta Technologies, a leading provider of integrated professional trunking communication solutions, today announced the launch of the Caltta DH400/410/460, a digital two-way radio series with versatile and practical push-to-talk features and compact, rugged design to keep the team connected in various work scenarios. With DH5 series, and the new DH4 series, the Caltta DH series now becomes the most complete digital two-way radio portfolio in the market for the small and medium sized enterprises and businesses.

Caltta DH400/410/460 radios, compliant to digital mobile radio (DMR) standard, deliver loud and clear audio in different environments. The 2 watts high-power speaker, combined with optimized front and rear sound cavities, releases loud and clear sound with maximum efficiency. The built-in single-MIC noise reduction algorithm effectively filters the background noise. In a typical work environment, the noise can be reduced by up to 13 dB.

Caltta DH4 series radios achieve 0.16uV(-123dBm) high receiving sensitivity through the optimized RF circuit layout and long helical antenna. The communication distance is 15% longer than most radios of the same grade in the market. DH4 adopts optimized digital power saving technology. In the 5:5:90 traffic model, i.e., 5% of the time in transmitting, 5% in receiving, and 90% in standby, the standard 2500mAh battery lasts for 18 hours in the analog mode and 25 hours in the digital mode. The radios fully meet the requirement of long work hours.

DH4 radios support the conventional DMO/RMO of analog/digital mode. In conventional digital mode, DH4 series support registration/deregistration, radio check, remote stun/revive, lone worker, roaming, etc., to assist users with efficient communication and dispatch. They are compatible with radios of other brands in analog/digital communications.

“The Caltta DH4 radios are designed to facilitate group communication and collaboration in various work environments, such as factories, shopping malls, hospitals, and schools,” said Leo Li, Sales Director Overseas of Caltta Technologies. “They can work as reliable communication tools in all the challenging conditions, since they survive many durability tests, and they are IP65 protected. DH4 radios are workhorse radios.”
