Introduction
The PE950 and PE960 Telephone Test Set is an advanced, convenient, and easy-to-use
telephone line troubleshooting device. Equipped with a number of LEDs and alarms, they let
the user know the operating mode and provides alerts for hazardous situations.
LEDs: Polarity
Low Battery
Talk/Monitor
Tones: Low Pitch
Middle Pitch
High Pitch
The LEDs and tones indicate various conditions and functions. They are shown throughout the
manual in italic type.
The PE950/PE960 produce two types of alarms to alert the user to potentially hazardous
situations.
• Excessive DC voltage is indicated by three low-pitched tones in a row.
• AC line voltage is indicated by continuous ringing.
If you hear either of these alarms, which are repeated in bold italic type in this manual,
remove the test set from the line carefully and immediately.
