The ATW-T1801 UniPak™ body-pack transmitter includes a field-replaceable flexible antenna. For	1	Antenna
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 transmitter positions or try
repositioning the receiver. Since the transmitter antenna simply screws in, check to make certain
it is snugly attached (finger-tight).Do not change the length of the transmitting antenna.
Green light indicates power is on and un-muted; red light indicates that audio is muted.	2	Power-on LED
The light will blink when the batteries are low.
Liquid Crystal Display presents setup and operating information. The LCD in the transmitters is	3	LCD
designed for greatest contrast and best viewing with the window rotated somewhat away from
the viewer (about 30 degrees), not straight-on, for a more convenient holding/viewing
position. The display is illuminated with a backlight when you press Set to access transmitter
functions. The backlight will automatically turn off within a set period of time.
Connect an audio input device (microphone or guitar cable) to the audio input jack on the bottom of	4	Audio Input Jack
the ATW-T1801 UniPak™ Body-pack Transmitter. A number of Audio-Technica professional
microphones and cables are available separately, pre-terminated with a compatible input
connector (see page 14 ). The cable connector latches automatically when inserted into the
transmitter jack. To unlatch and remove the connector, pull up on the connector’s knurled
metal collar.
The ATW-T1802 plug-on transmitter has a 3-pin XLRF-type input connector with a locking collar.	5	Microphone Input
Use either a dynamic or a condenser microphone. The transmitter provides power to condenser
microphones rated to operate on 12V phantom power or less. To attach the microphone, rotate the
threaded locking collar fully clockwise (”down”) until it reaches the transmitter housing (see (a)
at right ). Press the microphone and transmitter together (see (b) at right ). Rotate the threaded
collar ”up” until it is firmly against the end of the mic (see (c) at right ). Make certain the mic is
securely attached before use. To detach the microphone, reverse the steps above. Always			a	b	c
