<\/p>\nProduct Introduction:<\/p>\n
SD300K is a compact and lightweight design digital portable radio with 1.8-inch colorful LCD display, developed with DMR\/TDMA standards 4FSK modulation. It employs digital voice and dual-timeslot technologies to provide superior audio quality and optimal fidelity. It includes several features to enhance performance including: 64 zones 1024 channels, dual-time slot, digital voice encryption, VOX, battery save, DCDM(dual capacity direct mode) etc. The battery can get more extra working time compared to analog radio and with longer standby time thanks to DMR and battery save technologies. It provides cost-effective and easy-to-use radio communications with excellent performance for various users. SD300K supports both analog and digital modes, and is compatible with existing conventional analogue radios to ensure a smooth transition from analog products in use to digital products.<\/p>\n
