- Commodity name： DR-200 Mini 2W Digital Two Way Radio Walkie Talkie
- Model Number： DR-200
- Brand： Kydera
- Product Origin： China
- Type： Digital
Category：
Detailed Introduction
-advanced digital technology.
-TDMA digital technology.
-low noise, clear and loud voice.
-advanced voice encoding technology.
-supports both digital and analog working modes.
-True-2-slot:communication in direct mode, enabling two groups to communicate atthe same frequency simultaneously;doubling the efficiency and frequency utilization.
-support digital and analog mode, and be compatible with existing normal analogproducts or systems,to ensure a smooth transition from analog products to digitalproducts,thus improve the product utilization.
-Adopting 1.4" TFT color display, the operation is simple and clear at a glance.-A definable key for presetting common functions.
-support conventional license-free FRs channels:
-Customized products support up to 4000 channels to meet more communication needs(Total 16 zones and 250 channels per zone)
-With 2000mAh polymer li-ion battery pack to ensure long-term work.
-With the digital voice error correction processing technology(AMBE+2TM), the clearvoice performance is excellent. No matter in various usage environments, it canprovide clearer voice quality than analog walkie-talkies.
