nect the alligator clips or the modular plug to the line to be
tested. The FOX will not seize the line on most phone sys-
tems.
8.1.3: CONTINUITY / TALK
When the Function Switch is set to the CONTINUITY / TALK
position, the FOX can perform basic Continuity tests, or sup-
ply Talk Power to several “talksets”.
8.1.3.1: Continuity Testing:
The FOX can be used as a visual continuity indicator. Set the
FOX’s Function Switch to CONTINUITY / TALK. When the
FOX’s red and green alligator clips are touched together, the
LED will light, indicating continuity. To check continuity,
connect the red and green alligator clips to the circuit under
test and observe the LED. Continuity from zero to 10K ohms
will be indicated by the brightness of the LED. The LED will
be bright at low resistances and dim at high resistances.
Do not attempt to measure continuity on a powered line.
8.1.3.2: Talk Power:
The FOX will supply power to operate handsets. This fea-
ture is particularly useful when two installers are working at
terminal panels that have at least one identified pair con-
nected between them, but are not yet connected to the CO
battery. The FOX allows the installers to communicate us-
ing their handsets. Set the FOX’s Function Switch to Conti-
nuity / TALK and connect the handsets as shown in Figure 3.
The FOX’s LED will light when supplying Talk Power.
