MODEL A15TG MICROPHONE LEVEL TONE GENERATOR

The Shure A15TG Tone Generator is a battery-powered 700 Hz signal
source that can be used to troubleshoot low-impedance, balanced-line
microphone inputs.
The A15TG includes a recessed On-Off switch and a three-pin XLR au­dio connector. A removable end cap allows easy battery installation and
removal. The A15TG can also tolerate the presence of phantom power,
or a short circuit in the line it is driving. Built-in short circuit protection al­lows normal operation to resume after a short is removed.

BATTERY LIFE

The A15TG can operate continuously for approximately 1000 hours on
one 1.5V alkaline battery. To conserve battery power, make sure the
On-Off switch is in the Off position when the A15TG is not in use.

BATTERY INSTALLATION

1. Unscrew the end cap.

2. Insert the battery with the “+” terminal facing the “+” mark inside the
end cap.

3. Reinstall the end cap.
