Polarity Testing
1. Set the switch to OFF/POL.
2. Strip the wires. Use the alligator clips to
connect the 45081 Tone Generator to the
wires. The LED will glow when the red
alligator clip is connected to the positive wire
and the black alligator clip is connected to the
negative wire.
• The LED glows brightly to indicate an
inactive line (on-hook condition).
• The LED glows dimly to indicate an active
line (off-hook condition) or faulty line.
Note: Do not set the switch to TONE –
this would send a loud warbling tone
to the customer.
