[. . . ] It explains how to adjust them to satisfy your individual transmission requirements. · The necessary modules for this receiver system are incorporated into a "Mainframe". For programming and servicing, the EM 1046 RX receiver modules can be removed to the front. Output module, input module and mains power supply module, however, are integral parts of the system. IMPORTANT INFORMATION Each HF input is supplied with a wideband power distributor 1:3, which intendedly does not affect the adjustment possibilities of the EM 1046 RX receiver modules. In order to achieve sufficient sensitivity and protection against subscriber's extention stations, an antenna with booster and pre-selection is required. [. . . ] The switches at the left-hand side of the XLR outputs ("PAD") allow to attenuate the output signals by 20 dB.

"THE CAT": NOTA BENE Put the transmitters to work (see their user's guide). Check whether or not the transmitters' battery capacity is sufficient for the planned applications. Sennheiser SK 50, SK 250 and SK 5000 Mikroport transmitters automatically transfer data on the condition of their batteries or rechargeable battery packs to the EM 2003receiver. If the LowBatt indicator starts blinking on one of the displays, the batteries or rechargeable battery packs of the transmitters concerned are to be replaced or recharged.
