The operation of the Sperry Gyro-Compass is made easy by making all
parts as simple as possible.
In starting the equipment it is necessary to turn but one switch. The
twin wheels immediately start spinning and will in a short time come up
to the normal speed.
After the speed has been attained, a short time is allowed for the
wheels to cause their axes to “settle,” or, in other words, to seek and
hold the meridian.
In case of failure of the ship’s supply, or other trouble, an audible
signal immediately gives indication that something is wrong. This is
a decided improvement over the ordinary compass, as no indication is
afforded of the presence of factors which cause errors in its reading.
