transmitter while you unhook one end of the neck strap
from the breastplate. Fold the transmitter yoke flat,
being careful not to put a sharp bend in the transmitter
cord.
5. Wrap the neck strap around the coil and the
headband two or three times and snap the end back on
the breastplate; then fold the mouthpiece up against the
junction box. You now have a neat, compact package for
stowage, as shown in figure 4-5.
6. Put the phone into the box or hang them on the
hook provided. Be careful not to crowd or jam the leads.
Headset phones should always be unplugged when
they are not in use. If they are left plugged in, the
earpieces will pick up noise and carry it into the circuit.
Never place the phones on the deck. Not only is it
possible that someone may step on them, but decks are
good conductors of noise, which can be picked up by the
phones.
THE HANDSET
The handset telephone shown in figure 4-6 is held in
one hand with the receiver over one ear and the
transmitter in front of the mouth. A button, located on
the bar connecting the transmitter and the receiver, is
pushed down for talking. (The button must also be
depressed [pushed down] to listen.) (NOTE: If the
button is held down at other times, all of the noise at the
talker’s station will go throughout the circuit and make
it difficult for other talkers on the line to understand each
other.)
When not in use, the handset telephone is held on a
bracket on a bulkhead with a lever or spring attachment
that keeps it from being jarred loose. When you replace
the handset in its bracket, be sure it is secured so that it
cannot fall to the deck and be damaged.
