Recommended Calibration Procedure
The CP 52S is a very versatile instrument. While this allows it to conform to the requirements of a large number of system applica-
tions, it also results in complexity. For this reason, it is very important to use an organized approach to system calibration. Once the
system is connected and the internal switches set for your specific application, it is important to take the time for proper calibration.
The following is an ordered list of system adjustments that makes calibration easy and results in optimum performance.
This procedure assumes that a microphone is used for the Page. The procedure (except for the exact wording) is the same for other
Page sources.
Make sure the POWER is off!
