Synexis – Trouble Shooting

General instructions for a trouble-free operation
• Make sure that the transmitter and receiver are on the same frequency.
• Check the batteries and replace or recharge them if necessary.
• The transmission range depends on various factors such as local, constructional conditions. It can be reduced due to shadowing effects of
metal partitions (e.g. in lifts), high production machinery and reflections from metallic objects. Taking all negative circumstances into account,
the average transmission range is between 30 and 50 m.
In practice the group should not have more than 30 participants, as the length of the group could extend beyond the transmission range of
the system. Furthermore, the group should be kept within optical vision for safety reasons.
• To avoid popping try holding the Synexis TH2 microphone at a slight angle below the mouth.
• Blowing into the microphone to check that it is working can cause serious damage. Speaking a few words or counting is recommended.
