Introduction
The 46054 GTS-D Butt-in Test Set is an advanced, convenient, and easy-to-use telephone line
troubleshooting device. Equipped with a number of LEDs and alarms, the 46054 lets 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 46054 produces 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.
