+In addition to the DECT telephones, handheld radios are used for communication purposes. They serve as backup at important points in case the DECT network fails and are also used for 1:n communication.
 
 You may find a radio at your shift. In this case please make sure that the battery is not empty, the correct channel is set and the device is loud enough for you to understand. Communication always starts with an initialisation phase with call signs. Because most likeley no one knows that you are the security angel at the door, you should use "Entrance Glass Hall" as your call sign, not your real name or your nickname. For example: "Secu for Entrance glass hall" - "Here is Secu, go ahead".

 Usually, a lot of highly motivated people are keen to help with buildup, but after the event, most people are tired and want to get home to rest. The more people stay a day or two longer and help, the faster we all will be able to watch all the talks we missed during the event while relaxing at home.
