Interface free, private communications DTR Series radios give you peace of mind and keep your team focused on the task at hand, by making your communications more private. To take advantage of Private Communications, you can quickly set up your radio fleet with a unique Radio Profile ID Number. By choosing from 10,000 available codes, you can assure privacy from other neighboring radios. Leverage Frequency Hopping Spread Spectrum (FHSS) technology for more reliable and private communication when compared to standard analog radios. Flexible call options Digital one-to-one private calling allows private communications with a specific user. The recipient receives an alert - either audible or vibrating - and their radio displays the caller?s ID. Digital one-to-many group calling enables public group calls. All other DTR Series radios on the same group ID and channel can hear communications.
