Using the EM 9046
Example 2:
6 tr
ansmitters of type B1–B4,
8 transmitters of type B5–B8
Let us assume that you have only 6 transmitters of type B1–B4 but
8 transmitters of type B5–B8.
The number of transmitters is sufficient but the booster frequency range
B6 does not provide a sufficient number of unused frequency presets in
interference zone “HD”. You could therefore use the booster frequency
ranges B5, B7 or B8 but you should select the booster frequency range
with the highest number of unused frequency presets: B8.
In this example, there was a sufficient number of unused frequency pre-
sets available for interference zone “HD”, allowing you to adjust the “HD”
transmission mode for all channels. If this is not the case, you can, in a later
step, also adjust the “LR” transmission mode for individual channels.
To activate the booster frequency range:
왘 Select a suitable booster frequency range by turning the jog dial G.
The frequency range is highlighted in blue.
왘 Activate the booster frequency range by pressing the jog dial G.
“active” appears below the activated booster frequency range (see
above diagram). You can still change your selection by choosing a dif-
ferent booster frequency range and then pressing the jog dial G again.
왘 Finish the frequency scan and store the previously activated range by
pressing the button F.
왘 Assign frequency presets to the channels as described in the next sec-
tion.
Is there a sufficient
number of transmitters
of the correct type?
