Operation
The test set must have a good 9V battery installed in order to operate.
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

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.
