4 Evaluating the frequency scan and selecting a suitable booster frequency range The recorded interference levels are divided into 4 interference zones. The nuber of unused frequency presets is displayed per booster frequency range and per interference zone: B please select 13:48:38 booster range B2 B3 B4 B5 freq scan B6 B7 B8 Booster frequency range B1...

6 Assigning frequency presets 1. Call up the detail scan enu ite. detail scan Nueric easured values 2. Start the detail scan (optional). Selected frequency preset 3. Press a Channel button. 4. Select a frequency preset or select auto. LR LR/ /LR auto detail scan 5. Press the next Channel button. The auto setting autoatically assigns the frequency preset with the lowest EMI/RFI available in the selected booster frequency range. Thus ake sure to assign the ost iportant channel, e. g. the lead vocals, at first Store your setting.

8 Perforing a walk test RF level recorder 1. Switch on sources of interference and other transission links. 2. Call up the ch operating ode. 3. Switch on all transitters that you want to use for the walk test and establish transission links between the EM 946 and the transitters. 4. Press a Channel button. 7. Perfor the walk test; the antenna signals and the diversity evaluation are recorded for each channel. Use one or several transitters to walk-test the operating environent. If necessary, set arkers (SKM 9 COM or SK 9 with KA 9 COM). If necessary, you can additionally activate the 1 khz test tone to check the signal quality. Change between the channels to view the antenna signals and the diversity evaluation. 8. Interpret the result. Diversity evaluation A B Start fullscan Antenna signals RF IN A RF IN B no signal cd 5. Call up the RF level recorder enu ite. 6. Start the walk test. CH 1 : :3 1: 1:3 2: in Low antenna signals: RF signal cannot be evaluated, the window is highlighted in light gray 9.
