The referees must be in the hall in time. This is necessary so that they can carry out all the necessary preparation without time pressure and they are able to react in time if any problems arise. The appearance of the referees should be self-confident, friendly and in no case arrogant. Unequal treatment of the teams should be avoided. Particularly intimate greetings with individual team members can contribute to a feeling of disadvantage of a team.
It is important that the referees communicate with each other. This applies before the match (match preparation), during the match and after the match (checking scoresheet). A well-coordinated team of referees appears confident and trustworthy.
Keeping to a certain form gives a clear and tidy picture and has a calming effect on all participants. Correct mechanics (e.g. looking at the receiving team of the second referee), the willingness to react to mistakes (whistle in the mouth during the rally) and the behaviour during set intervals and time-outs (no loafing around) indicate the competence of the referees.
Refrain from instructing players, coaches or other officials of a team during the match. Although rules can briefly be explained to them, matches are not the right place and time for teaching rules.
The scorer's desk should be clean and tidy. Although the scorer may have non-alcoholic (!) drinks ready, they should be kept in such a way that they do not pose a danger to the scoreboard and score sheet.
If scorers eat on the scorer's table, the referees must stop them. The use of mobile phones impairs concentration on the game and must therefore also be stopped.
