FM - Microphone adjustment in DCN
Microphone stem
When the microphone stem assembly has to be replaced, it is required that the input level of the
microphone is adjusted again by use of the preset potmeter R(x).. This due to the spread in
sensitivity of the microphone capsule (approx.. ±3dB).
Procedure
The adjustment is a practical procedure to compare factory adjusted units with units were the
microphone stem is replaced and to be tuned to the system level again.
Measurement data output and adjustments is represented by the symbol 
Test procedure
1 - Connect the Delegate unit with the CCU.
Comment
.
Select mode only one active mic. on the CCU!
2 - Connect to the ‘Line out’ of the CCU the
AC mV meter
3 - Adjust the audio source to approx. 1kHz.
The audio level of the lsp. should be distortion
free and at a level of speaking distance Takes
care that no acoustic nuisance from outside
influence the measurements.

FM - Microphone adjustment in DCN
Test procedure
4 - Place the mic. of a factory adjusted
Delegate unit close to the loudspeaker on
a fixed distance.
 Measure the audio level on the AC meter.
5 - Remove the factory-adjusted unit and
place the unit for adjustment in the same
position.
 Read the audio level on the AC meter.
 Tune R(x) to the audio ref. Default as
measured before.

Comment
.
Idea, make from an old DCN microphone head
housing an audio reference source.
Mount inside the (empty) head e.g. a paging
bleeper as ref. loudspeaker.
Important is that for all measurements the
distance between loudspeaker and microphone
is equal.
Take this level as ref. for the DCN FM units to be
adjusted. Repeat the ref. measurement for a
check with other unit(s).
The factory level adjustment is ±0.5dB
Do not change the audio setting adjustments.
For the LBB3537/xx, tune the +/- 3dB adjustment
potmeter of the LBB3535/xx or LBB3540/xx
