Level Setting of System Components
The remote will key the transmitter and then begin sweeping the audio band from low to
high. The display should appear as shown in
. To step up or down through the
range of frequencies use the “9” or the “7” key respectively. The frequency displayed in
the screen will change, and its current output level will be displayed. To get the sweep to
pause and remain on a single tone long enough to make a measurement, press the “7” or
the “9” key and hold it down for as long as the measurement takes. This takes a little
technique since the unit will always step as you press the key and then stop on the next
tone as you hold it.
Figure 12: Setting the Equalization Curve
If your measurement indicates that the tone’s level needs to be increased or decreased,
release the key you are holding and use the “*” or “#” keys respectively to lower or raise
the tone’s output level. The new output level will be displayed as you change it.
Repeat steps 3 and 4 until the unit can sweep through the whole range without the
deviation level on the service monitor varying excessively at any point.
Press the “1” key again to save the equalization curve #1 settings (you would use “2” with
curve #2). The deskset displays the message “Comprehending...”, as shown in
while it stores the new curve data in its memory. When it finishes this and returns to the
Setup mode prompt, press the CLEAR key or the function #9 to exit the Setup mode.
Figure 13: Exiting the Equalization Test
Once the curves have been adjusted for the system in the remote deskset you were using,
the ZIPR software can be used to read the new data to a file on disk and to clone that data
into other remotes to save having to run this test on each and every unit.
