You have the opportunity to choose between 16 channels. Channels can be switched manually or automatically via the built-in synchronisation function. After selecting a channel, the receiver locks automatically, so that an accidential channel switch is impossible.
The devices are very easy to use, so everyone, no matter how young or old, will be able to use them intuitively. Besides the chosen channel, the LCD display also shows you the volume level, storage battery level and system state.
The built-in batteries ensure an uptime of 15 hours for the transceiver. For the receivers guaranteed uptime is up to 20 hours.
