Installation and starting up Installation and starting up 4.1 General Information Unpack and check carefully there is no transportation damage before using the unit. Keep the equipment packaging. To fully protect the product against vibration, dust and moisture during transportation or storage use the original packaging or your own packaging material suitable for transport or storage, respectively.
Page 19
For more information, please visit: http://www.thomann.de. Make sure that transmitter and receiver are both tuned to the same channel.
Installation and starting up 4.2 Receiver Rack mounting The unit has been designed for rack mounting in a standard 19" rack; it occupies one rack unit (RU). The fixing material required for assembly is included. Connecting the power supply NOTICE! External power supply The device is powered by an external power supply.
Page 21
Installation and starting up Attaching the antennas Attach the included antennas to the rear panel of the transmitter. To improve the transmission quality and to adapt to the spatial conditions they are rotatable and swivelling. In case the space provided on the device for direct assembly of the antennas is not sufficient, for example because the space on the rack is narrow, you can use the optionally available coaxial cable to assemble the antennas separately from the device.
Installation and starting up 4.3 Handheld microphone Inserting batteries Unscrew the bottom housing section of the handheld microphone. Insert the batteries. Pay attention to the correct location of the poles. The correct battery arrangement is illustrated in the battery compartment. Close the battery compartment, screw the bottom housing section back on, and switch the transmitter on.
Installation and starting up 4.4 Bodypack transmitter Inserting batteries Squeeze the battery compartment lid, flip it open and and insert the batteries. Pay attention to the correct location of the poles. Close the battery compartment and switch the transmitter Connecting microphone of Ensure that the transmitter is switched off.
