Battery Condition Indicator

The Green Battery condition indicator(Figure I/ J) should light strongly with a fresh battery. As the battery weakens, the indicator will glow Red. When the Indicator becomes Red, there is little life left in the battery. Replace it at once for continued operation of the transmitter.

Battery Save Switch

ATW-T161 Transmitter features RF Lo / Hi Power switch (Figure E). As supplied, the switch is set in the Lo (Low) position for the maximum battery life. Hi(High) position can be selected for maximum range (Note range decreases when the switch is set at Lo position.)

Special Note: If accessing de-regulated frequencies between 863 to 865MHz(Ch. C to F), ATW-T161 must be set to RF Low.

UniPak Transmitter Input Connection

Connect an audio input device (microphone or guitar cable) to the audio input connector on the bottom of the transmitter. A number of Audio-Technica professional microphones and cables are available separately, pre-terminated with a UniPak input connector (see “Optional System Accessories” on page 9).

Transmitting Antenna

The UniPak transmitter includes a permanently-attached flexible antenna. For best results, allow the antenna to hang freely and full length from the bottom of the transmitter. If the received signal is marginal, experiment with different transmit- ter positions on your body or instrument; or try repositioning the receiver. Do not attempt to remove, replace or change the length of the transmitting antenna.

The antenna for the ATW-T162 and ATW-T163 handheld transmitters are located at the bottom of the units. For the best results, hold the Microphone naturally around the centre of the body.

Holding or otherwise covering antenna housing may affect operating range.
