TMC LINESMAN'S TELEPHONE 704 Istallation And Operating Instructions

2. Local Battery Working
When communication is required between two telephones proceed as follows:-
a) Set the three-position slider switch to the LB position; the
internal battery is now in circuit.
b)
Connect the telephone to the line.
c) Push the slider switch to the 'RING' position to call the other
station. A tone will be heard in the receiver.
d) Arrange with the other party which battery is to be in circuit
as it is only necessary for one internal battery to be in use,
therefore one telephone should have the slider switch in the
LB (battery in circuit) position and the other telephone should
be switched to the CB (battery out of circuit) position.
e) To conserve battery and receive incoming calls always replace handset
or remove headset plug from socket.
3. Tone Amplifier
A tone amplifier may be used to identify cable pairs. The tone can be heard
in the telephone headset if the output of the amplifier is connected to the
sockets in the linesmans telephone.
