Battery Selection and Installation

Always use a fresh alkaline 9V battery. Turn the Power switch “Off” before inserting a battery.

Open the hinged battery door. Insert the battery, observing correct polarity as marked inside the battery compartment. Close the battery door. Do not force the door closed.

Battery Condition Indicator

After the battery is installed, turn the power on. The battery condition indicator LED (Fig. D) should flash momentarily.

If it does not, the battery is installed incorrectly or it is dead.

If the indicator LED stays on (does not flash), the battery voltage is low and the battery should be replaced. If this happens during use, replace the battery immediately to ensure continued operation.

ATW-T102(x) Microphone Input

The ATW-T102(x) plug-on transmitter has a 3-pin XLRF-type input connector with a locking collar. Use a dynamic microphone, or a condenser mic with an internal battery. To attach the microphone, rotate the threaded locking collar fully clockwise (“down”) until it reaches the transmitter housing (Fig. E1). Then rotate the collar back “up” one or two turns to expose the microphone latch.

Press the microphone and transmitter together (Fig. E2), making certain that the latch “clicks” into the base of the mic. Pull on the mic to make certain it is latched on the connector.

Continue to rotate the threaded collar “up” until it is firmly against the end of the mic (Fig. E3). Make certain the mic is securely attached before use.

To detach the microphone, reverse the steps above. Always loosen the threaded collar fully before attempting to disconnect the mic.

The ATW-T102(x) provides a bias voltage of +5V on Pins 2 and 3 which will power some “battery/phantom” mics designed to work at this low voltage. However, the ATW-T102(x) will not power a “phantom powered” mic which requires the more-typical 12 to 48 volts. Use of the bias voltage will reduce battery life slightly. Presence of the bias voltage will not affect dynamic microphones.

Transmitting Antenna

The ATW-T102(x) plug-on transmitter's antenna is housed in a non-metallic section between the metal transmitter case and the mic connector. For best operation, hold the body of the microphone itself and do not cover or obstruct the antenna area.
