Using the EM 9046
Example 2:
6 transmitters 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?
