Without inserted headset the ATT 100 represents a standard 2-way radio in the UHF PMR
446 frequency range for internal communications. (The inserted headset does not allow any
reception, because the earpiece can only be used for MP 3 playback). Communicate with
other Tour Guides just by using the internal PTT and internal microphone and speaker.
Please take care that all radios used for the communication are switched to the same
channel number.
