Handheld Transmitter Battery Installation
1.
While holding the upper part of the transmitter body by the
translucant ring below the ball-screen, unscrew the lower
body cover, slide it downward, and remove it to expose the
battery compartment.
2.
Observe correct polarity as marked inside the battery
compartment and carefully insert two fresh 1.5V AA
alkaline batteries. Insert the first battery and slide it down.
Then insert the second battery into the space remaining.
Make certain the batteries are fully seated in the battery
compartment. (Fig. F)
3.
Slide the lower body cover back up the body, then screw
the housing together. Do not overtighten.
Note: Remove batteries from the handheld transmitter starting
at the bottom end, where finger indents in the battery housing
are provided for easy grip.
Battery Indicator
After the battery is installed, turn on the power switch (located
on the bottom of the handheld transmitter and on the top of the
UniPak transmitter). The battery indicator LED (Fig. G/H) should
turn red. If it does not, the batteries are installed incorrectly or
they are dead.
UniPak Transmitter Input Connection
Connect an audio input device (microphone or guitar cable) to
the audio input connector on the top 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 10).
UniPak Transmitter Antenna
The ATW-T210 UHF transmitter includes one field-replaceable
antenna mounted on the transmitter. The antenna simply
screws into the transmitter’s antenna fitting. Check the installed
antenna occasionally to make certain it is snugly attached (only
finger-tight). If the received signal is marginal, experiment with
different transmitter positions on your body or instrument or try
repositioning the receiver.
Do not attempt to modify the
transmitting antenna. Replace it only with the same parts
,
available from the Audio-Technica Service Department.
