Figure 1-7.Supply, control, and telltale panel.
The energizing of the signal searchlights, infrared,
and other related equipment is covered in chapter 2.
However, as a Signalman, you should also know how
to locate and operate the switches for your ship's
running lights. You should be able to do this in the
dark. The light panel, shown in figure 1-7, is located
in the pilothouse; it controls the switches for the port
and starboard running lights, towing lights, masthead
light, second masthead light, and stern light. It affords
an audible and visible signal when the primary
filament burns out in any of the five running lights. At
the same time, it automatically switches to the
secondary filament so that the defective light remains
in service. Although the light remains in service on the
secondary filament, the electrician should be notified
so the defective lamp can be replaced at the earliest
opportunity. In addition to the running light control
panel, there is a signal and anchor light supply and
control panel, also located in the pilothouse. The
supply switches for these lights are individual
ON-OFF rotary snap switches. This panel normally
controls the aircraft warning lights, blinker lights,
not-under-command lights, steering lights, stern light
(blue), and wake lights.
The Not-Under-Command light switch is fitted
with a crank handle to facilitate pulsating when the
lights are used as a man overboard signal.
Learn where each individual switch is, and also
where the master switch is located. In the event of an
emergency, you must be able to turn the correct switch
at the proper time.
In this chapter you were informed of some of the
many tasks that compile the Signalman rating. These
tasks ranged from sending and receiving messages by
semaphore, flashing light, flaghoist, and radio, and
lookout duties, to obtaining and updating
publications. You were taught that to be successful you
must be willing to work hard to master the varied skills
used by Signalmen. You were reminded that your
ability to perform your duties affects the operation of
your ship, as well as other ships with whom you
communicate. Your Navy and your Country need TOP
QUALITY SIGNALMEN. Will you qualify?
