Tempo Communications PE930 Manuel D'instructions page 7

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.
TALK
Press once to go off-hook (connect). Press MONITOR to go on-hook (disconnect).

Automatic Line Checks
The PE945/PE961 is designed to allow testing of POTS service on a live xDSL line with reduced
risk of bringing down the data service. At any attempt to go Off-Hook, the test set automatically
performs the following line checks:
1. Digital Signal Presence (PE961 only): 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 the TALK
key. 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 test set 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 test set locks out. The alarm
may not be overridden.
The PE930 does not include these features.
