Do not use cleaning fluids or antirust
compounds on transmitter, receiver
units, or other component parts of
handset. Discoloration or tarnish on
the silver-plated contact surfaces is
not objectionable and no attempt
should be made to remove it.

Use care when cleaning handsets to avoid
marring the finish. Replace handset if clean-
ing does not result in a satisfactory appearance.
3.03
Replace cut, worn, cracked, or badly frayed
cords. Connections should be checked at ter-
minals.

following procedure should be used.
( 1
J
Fold back the spade-tipped conductors over
cord jacket ahead of grommet, feed through
hole at end of handle (transmitter end), shown in
Fig. lOA.
(2) Pass the leads through hollow handle (folded
over, Fig. lOB and lOC) into the receiver end
of handle.
(3) Retrieve the two white (receiver leads) lead
loops and pull free (Fig. lOD). Hold the free
end of these leads and retract the cord to obtain
the red and black leads at the transmitter end of
the handle (Fig. lOD).
( 4) Terminate conductors and replace cup assem-
bly shown in Fig. 2.
(5) Replace transmitter and receiver units and
associated caps.
3.05
Locking devices for G-type handsets are not
available. If necessary, for security reasons,
caps may be cemented to the G-type handles. Use N-
170 cement (Armstrong Corp. Co.). The application
shall consist of coating the handle threads from the
top of the base over an area 112-inch in length in two
opposite places. The caps shall then be tightened by
hand. Additional tightening may be applied using a
514-type tool, but apply no more than 112 turn.
