Modification of SENNHEISER Tourguide 2020 systems

UNOG Interpreation Service has a requirement to modify two Sennheiser Tourgide 2020 systems for field use with the purchase of lightweight headsets/receivers (EK 2020) and the modification of the charger system. The modification must result in the following: - portable, with ease of use for both, clients and interpreters; - light, for purposes of travel, including on board of airplanes as hand luggage and in different field conditions; - time-saving in terms of use, charging times, and set-up/deployment; - robust and durable, with a special case to protect the equipment.
