Operation
The test set must have a good 9V battery installed in order to operate.
See "Changing the Battery or Cordset" in this manual.
1.
Connect the red wire to the ring (negative) side of the circuit.
2.
Connect the black wire to the tip (positive) side of the circuit.
3.
Use the Talk, Monitor and Mute features as described in this section.
Automatic Ground Start
Some lines, especially PABX, require a momentary ground to draw a dial tone.
Connect the test set's red and black wires to the telephone circuit as usual, and connect the
green wire to ground. Press the TALK button momentarily to check for dial tone.
The ground start is automatic, and the green wire can remain connected without affecting the
call.

Automatic Line Checks
The PE961 is designed to allow testing of POTS service on a live ADSL line without fear of
bringing down the data service. At any attempt to go Off-Hook, the PE961 automatically
performs the following line checks:
1. Digital Signal Presence: A two-tone alarm (middle pitch – low pitch) sounds and the
test set locks out. To override this alarm, e.g. on an ADSL line, press and hold the TALK
key until the alarm stops (~ 6 seconds). Once overridden, the alarm will remain cancelled
until the unit is either turned off or disconnected from the line.
2. High DC Level (76V-116V): A single-tone alarm (low pitch) sounds, the hook status
LED flashes red and green and the PE961 locks out. To override this alarm, press and
hold the TALK key until the alarm stops.
3. HIGH DC Level (>116V): A single-tone alarm sounds and the PE961 locks out. The
alarm may not be overridden.
