Performing a frequency scan 1. Position the antennas and connect the EM 9046 to the antennas. 2. Switch on the EM 9046, switch off the SK and SKM 9000. Switch on all possible sources of interference and other transmission links.

Evaluating the frequency scan and selecting a suitable booster frequency range Ex The recorded interference levels are divided into 4 interference zones. The number of unused frequency presets is displayed per booster frequency range and per interference zone: please select13:48:38 booster range 2011-11-01 Booster frequency range B1 ...
Example Required number of transmission links: 8 A sufficient number of transmitters of type “B5–B8” is available Desired transmission mode: “HD” Possible booster frequency ranges (see diagram on previous page) Unused frequency presets in interference zone “HD“ (see diagram on previous page) Number of required frequency presets in the following interference zones “HD” “HD/LR” “LR/HD” “LR” B5 29 8 0 0 0 B6 6 6 2 0 0 B7 26 8 0 0 0 B8 31 8 0 0 0 B5, B7 and B8 are suitable b
Assigning frequency presets M as 1. Call up the “detail scan” menu item. detail scan 2. Start the detail scan (optional). Numeric measured values Selected frequency preset 3. Press a “Channel” button. LR LR/HD 4. Select a frequency preset or select “auto”. HD HD/LR auto detail scan 5. Press the next “Channel” button. The “auto” setting automatically assigns the frequency preset with the lowest EMI/RFI available in the selected booster frequency range.
Manually setting and assigning a frequency Adjusting transmitter settings on the EM 9046 please select booster range Preset B8.23 Freq 787 . 400 MHz Range: 774 - 798 MHz Synchronizing the transmitter and receiver 1. Call up the “ch” operating mode. 1. Call up the “ch” operating mode. 2. Press a “Channel” button. 2. Press a “Channel” button. 3. Call up the “Transmitter setup” menu. 3. Press the “Sync” button. 4. Call up the “RF mode” menu item. 4.
Performing a walk test – RF level recorder 1. Switch on sources of interference and other transmission links. 2. Call up the “ch” operating mode. 7. Perform the walk test; the antenna signals and the diversity evaluation are recorded for each channel. 3. Switch on all transmitters that you want to use for the walk test and establish transmission links between the EM 9046 and the transmitters. Use one or several transmitters to walk-test the operating environment.
