RECOMMENDED CALIBRATION PROCEDURE
The CP 52 is a very versatile instrument. While this allows it to conform to the requirements of a large number of system
applications, it also results in complexity. For this reason, it is very important to use an organized approach to system calibra-
tion. 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!
