The gyrosphere (Part No. KT005) is the heart of the CMZ 700 system, containing the sensitive spinning mass that detects Earth's rotation to find true north. This critical component has a defined lifecycle.
Repeaters show different heading than master.
Usually caused by extreme weather or rapid maneuvers. The system may require a manual reset or additional settling time. Safety and Compliance

The Yokogawa CMZ 700 series (including the 700B, 700S, and 700D models) is a versatile gyrocompass system designed to provide reliable heading data for various vessel types 1. Key System Components The system configuration depends on your specific model: Master Compass (MKM 022) The core unit containing the gyrosphere. Control Box (MKC 320/321):
Proper operation starts with understanding the startup sequence and control unit functions. 3.1 Startup and Stoppage (Section 4.1 of the Manual) Repeaters show different heading than master
If a transient glitch is suspected, turn the system off for 5 minutes and restart it.
The Yokogawa CMZ 700 gyrocompass remains a robust and reliable navigation instrument for a wide range of vessels. By understanding its specifications, system variants, and the detailed instructions within the user manual, maritime professionals can ensure optimal performance and compliance with safety standards. Regular maintenance, lifecycle management, and access to authorized support are key to maximizing the lifespan of this precision instrument.
The CMZ 700 compensates for earth’s rotation based on latitude.
