Description

The SW**0/*0A/*0B/*0 Wireless discussion system is a discussion system for using in meeting and conference venues with a limited number of participants. The SW**0/*0A/*0B/*0 Discussion System consists of: One Control and power supply Unit (SW**0) Maximum *0 units , includes one or more chairman unit(s). Wireless access point SW**0 Extension cables if required (5m or *0m). Peripheral audio and /or telecommunication equipment. The system has the functions below: (1)open mode:to select the maximum number of delegate microphones to be actived simultaneously(1, 2, 3 or 4).The microphone must be switched on or off manually by pushing the button on the delegate unit. (2)override mode:only one deleagte microphone can be ***** a new delegate pressed his microphone button, the microphone unit of the current speaker will be switched off. (3)chairman only mode:only the chairman units can be activated. (4)test mode:for proper installation check.All the light rings and LEDs of the connected units will lit, if properly connected. (5)turn off mode:to turn off all units at the same time. Technical data SW**0 Mains voltage: *****0V AC *0/*0HZ Current consumption *5W(VA) at maximum load Power to SW**0A/*0B: 7.2V ***0mAh Lithium ion rechargeable battery: recharge need 3 hours, can last at least *0 hours Main input voltage for rechargeable battery: *****0V AC *0/*0Hz Max **0mA Main output voltage for rechargeable battery: 8.4V DC **0 mA SW**0A/*0B Wireless transmitting frequency: **0Mhz**0Mhz; **0Mhz±*0Mhz Wireless transmitting consumption: *0dBm SW**0 Receive frequency: **0Mhz**0Mhz; **0Mhz±*0Mhz Receive sensitivity: *0dBm System requirements: The maximum number of units in SW**0 system is *0.
