[Bosch Blue Line D1-P detector Setup]

Do you have any experience with the micorwave adjustment on a Bosch Blue

Line D1-P detector?  Part of the installation of some I have purchased form

you indicates to adjust the microwave sensivity, is this a normal part of a

standard installation for say a 10m x 10m room or do you always hae to fine

tune the detector?  Is there any further guidance notes for this task?
