Battery operation: If all eight LCD segments are showing, the full battery capacity is available. If four LCD segments are showing, about half of the battery capacity is still available. If the battery is going flat, only the last LCD segment is showing and the "LoBAt" warning flashes in alternation with the display of the transmission frequency / channel number. Accupack operation (display only if the Sennheiser BA 1032 accupack is used): If only the LCD segment on the right is showing, the accupack can be used. If the accupack is going flat, only the last LCD segment on the left is showing and the "LoBAt" warning flashes in alternation with the display of the transmission frequency / channel number. When a new accupack is inserted the right-hand LCD segment will indicate full capacity. As the accupack discharges this segment will remain on showing that the accupack is usable, when the accupack approaches full discharge the display will switch to showing the left-hand LCD segment as a warning (as described above). Accupacks from other manufacturers cannot be "identified" by the electronics and their capacity is therefore not displayed correctly. Press the corrugated area below the microphone body to unlock the protection/identification cap and push the cap backwards until you meet resistance. If several S KM 3072-U hand-held transmitters are used simultaneously, the protection cap ­ which is supplied in various colours ­ also serves as an identification mark. 13 Display of transmission frequency or channel number After you have switched on your SKM 3072-U, the microprocessor performs a self test which can be followed on the display. After about two seconds, the PLL has locked on the preselected transmission frequency and the standard display ­ the preselected transmission frequency or the channel number ­ is shown. whether the transmission frequency or the channel number is displayed. Your selection is stored and remains stored even if the transmitter is switched off and on again. button: The display of the transmission frequency is quite important for the technician as he can check in which channel grid the transmission is taking place, if the channels are interfering with each other and so on. button: The channel number ­ which is the same for both transmitter and receiver ­ is easier to monitor for the user on stage. 11 Sennheiser transmitters report their battery status to the receiver Together with the RF signal, the SKM 3072-U transmits inaudible information on its remaining battery or accupack capacity to the receiver. This information can be evaluated with the Sennheiser EM 3031/EM 3032/EM 3532 or EM 1046 receivers. 32 33 With only three buttons, you can adjust any function on the receiver on the transmitter 14 Basic functions of the Sennheiser operating menu 15 Adjusting the sensitivity A special feature of the Sennheiser 3000 series is the similar operation of transmitters and receivers. In stressfull situations, for example on stage or during a live show or presentation, it is important that the transmitter is easy to operate and that adjustments to the transmitter settings can be made quickly and "without looking". Therefore, the necessary operating steps for each device must be similar. When briefly pressing the SET button, the display indicates the preselected sensitivity. The possible settings for the ME 3005 e microphone head are the following: 0 dB - 10 dB - 20 dB - 30 dB for singers with soft voices for singers with normal voices using the microphone at a greater talking distance for singers with loud voices for rock singers / "close-miking" Press the SET button to get into the setting mode. By briefly pressing the SET button, the display begins to flash and you enter the top menu level. By briefly pressing SET again, the display switches to the next menu and so on. The possible settings for the ME 3005 microphone head are the following: 0 dB - 10 dB - 20 dB - 30 dB for speakers with soft voices for speakers with normal voices using the microphone at a greater talking distance for speakers with loud voices for "close-miking" (e. g. [. . . ] u chapter 8). Transmitter switches off during operation: After "LoBAt" ­ alternating with the display for frequency/channel number ­ has been shown for a certain amount of time, the battery has become completely flat, the transmitter has switched off (=> replace battery!u chapter 8).
