Operators which are using more than 200 QSLs will be asked for the covering cost of QSLs. The operating audio level must be maintained low enough in order to not disturb the normal ITU office work, and consequently the operators are asked to use headphones. The station must be kept tidy and clean. Since the station is kindly offered by the Secretary General of the ITU, smoking, drinking and sleeping are strictly forbidden. If damage to station occurs, a written report explaining the circumstances must be made.
All operators are liable for any damage caused through non - respect of the above rules.
