Deviation adjust
1. Using the RIS, press TX ON (Modulated) and record deviation level as read on the IFR.
2. Using Windows Notepad, Edit the .bp2 file named with the corresponding BDLC
PD
serial
number (e.g. abcd.bp1). “Save as” to another file name and keep it in case something goes
wrong while changing a parameter.
3. Locate the line labeled “Dev0 Par85=” and record the value beside the “=” sign. This is the
corresponding parameter value to the deviation read in step 1.
4. Apply the following formula to determine the new parameter value to be set:
(New Par85 value) = [(initial Par85 value) X (target deviation) / (deviation read)] + 2
5. Change the value in the file, “Save as” using the BDLC
PD
serial number file name.
6. Run the RIS again and do a “Put From”. From the opened window, select the file that you just
made the change to and then press “OK”
7. Again, check deviation level while pressing TX ON (Modulated). If fine-tuning of Par90 value
is still required, Edit the file again and re-do step 5 by changing directly the Par85 value by 1
or 2 up or down.
8. Re-check deviation level. If the level is now correct, press Stationreset to make the change
permanent.
