ESW-T211
UHF UniPak™Transmitter
Installation and Operation
Audio-Technica Engineered Sound®wireless systems
are offered as separate receiver and transmitter units,
rather than in predetermined combinations, for greatest
system flexibility. Operating details for Engineered
Sound receivers and overall system operation are
included with each receiver.
Engineered Sound receivers feature a sophisticated
Tone Lock
™
tone squelch system that opens only when
an Engineered Sound transmitter is detected, reducing
the possibility of interference. As a result, Engineered
Sound transmitters and receivers must be used
together and should not be used with components
from other Audio-Technica wireless systems, or with
those of other manufacturers.
Please note that in multiple-system applications there
must be a transmitter-receiver pair set to a separate
frequency for each input desired (only one transmitter
at a time for each receiver). Because the wireless
frequencies are on UHF TV frequencies, only certain
wireless frequencies may be useable in a particular
geographic area. Also, only certain of the available
operating frequencies may be used together.
(Suggestions for multiple-system frequency grouping
will be found on pages 10-11.)
Battery Selection and Installation
The transmitter uses two 1.5V AA batteries, not
included. Alkaline type is recommended. Always
replace both batteries.
Make certain the transmitter
power switch is turned Off before replacing
batteries.
Battery Installation
1. Slide down the battery latching cover and pull out
the battery drawer as shown in Figure A. (A screwdriver for adjusting operating frequency is stored on the
back of the drawer.)

Notice to individuals
with implanted cardiac
pacemakers or AICD devices:
Any source of RF (radio frequency) energy
may
interfere with normal functioning of the implanted
device. All wireless microphones have low-power
transmitters (less than 0.05 watts output) which are
unlikely to cause difficulty, especially if they are at
least a few inches away. However, since a
“body-pack” mic transmitter typically is placed against
the body, we suggest attaching it at the belt, rather than
in a shirt pocket where it may be immediately adjacent
to the medical device. Note also that
any medicaldevice disruption will cease when the RF transmitting
source is turned off
. Please contact your physician or
medical-device provider if you have any questions, or
experience any problems with the use of this or any
other RF equipment.
CAUTION! The circuits inside the receiver and
transmitter have been precisely adjusted for
optimum performance and compliance with federal
regulations. Do not attempt to open the receiver or
transmitter. To do so will void the warranty, and may
cause improper operation.

INPUT TRIMMERS: These controls permit adjustment
of Mic Level (MT) and Guitar Level (GT) to match a
wide range of input devices, as described in a following
section. The trimmer
not
in use should be set to
minimum.
CHANNEL SWITCHES: The left channel selector switch
corresponds to the receiver‘s left-column channel
display number (tens); the right switch corresponds to
the receiver‘s right-column channel display number
(units). Always turn the transmitter off when changing
frequencies.
RF POWER / BATTERY-SAVE SWITCH: As supplied, the
switch is set in the “Hi” position for maximum range.
Switching to the “Lo” position increases battery life
somewhat by reducing power. (Note: Effective range
may decrease when the switch is set at the Lo
position.)

2.
Observe correct polarity as marked inside the bat-
tery compartment
and carefully insert two fresh 1.5V
AA alkaline batteries. Because there is some
variation in actual battery dimensions, make certain the
batteries are
fully
seated in the battery compartment.
3. Carefully insert the battery drawer fully,
but do not
force the drawer in
. Then slide the cover up to latch
the drawer.
Battery Condition Indicator
After the batteries are installed, turn the power on. The
red battery condition indicator LED on the user control
panel should flash momentarily and the green indicator
should come on. If this does not happen, the batteries
are installed incorrectly or they are dead. If the yellow
or red indicator stays on, the battery voltage is low and
the batteries should be replaced. If this happens during
use, replace the batteries immediately to ensure
continued operation.
Transmitter Input Connection
Connect an audio input device (microphone or guitar
cable) to the audio input connector beside the user
control panel (Fig. B).
A number of Audio-Technica professional microphones
and cables are available separately, pre-terminated with
a UniPak
™
input connector (see “Transmitter
Accessories” on page 9).
Transmitter Controls
(Refer to Fig. B, User Control Panel)
POWER SWITCH: The Power switch controls the entire
transmitter. Its handle is designed to be felt and
activated easily even through clothing or other
garments. There is about a half-second delay after
transmitter turn-on before the receiver’s Tone Lock
squelch un-mutes.
HIGH-PASS SWITCH: The ESW-T211 offers an audio
high-pass switch which reduces low frequencies, when
desired. It affects only the microphone input and is
recessed to avoid accidental activation. Use this switch
to reduce pickup of low-frequency noise caused by
clothing and/or user movement.
