TMC 705 Installation 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.
