The third generation of Confidea has an innovative wireless engine that integrates the latest technological evolutions in wireless communication. It offers an even more robust transmission link and more available frequencies in various countries. The Confidea has also been engineered to perform in RF-challenging environments. The new engine is much more power-efficient, too. That's why Confidea G3 has a longer operating autonomy and requires recharging far less frequently. The Confidea G3 CD offers each chairman a microphone and a microphone button. This button activates the microphone instantly. The chairman unit has direct control over who's up next through the Next-in-line button. Additionally, he can override all other microphones and take the floor through the Priority button. The microphone (sold separately) is attached to the unit with a screw-lock connector and is immune to mobile phone interference. New in this generation is the simplified button layout with a reduced number of physical buttons. It offers delegates a less cluttered, more intuitive user interface so they can focus on what's important without technology getting in the way. The Confidea family of products uses Li-ion (Lithium-ion) batteries, the best type of battery technology for frequently used and rechargeable electronic equipment. Found in smartphones and tablets, this mature battery technology offers rapid recharging without the need for a full discharge. Li-ion batteries also have a longer lifespan with hardly any deterioration of the battery performance. Combined with the smart power management built into Confidea, the batteries will offer maximum autonomy: up to 28 hours on a single charge. A separate adapter even allows batteries to be charged while the system is operational.
