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.
