See Figure B-Front Panel Controls and Functions
1. POWER SWITCH: Press the Power switch in to turn the receiver on. The LCD
window will light, and the operating channel number will be displayed in the
window. To turn the receiver off, press the Power switch again.
2. LCD WINDOW: Liquid Crystal Display indicates channel setting and
operational readings. See Fig. C for examples.
3. UP/DOWN BUTTONS: Press Up or Down arrow buttons to arrive at desired
channel. The selected number will flash on and off. Press and hold Set/Scan
button to set the channel (operating frequency).
4. SET/SCAN BUTTON: Two distinct operations are associated with this button:
Touch : A momentary press of the Set/Scan button.
Hold : A press and hold (about two seconds) of the Set/Scan button.
The Set/Scan button can be used in two ways: Manual Set Mode, to permit
selection of an operating channel; and Automatic Scan/Set Mode, to initiate
E
the automatic channel scan and selection, as follows:
N
Manual Set Mode: After using the Up or Down arrow button to arrive at
desired channel, hold the Set/Scan button to set the channel. NOTE: Before
the channel has been set, a touch of the Set/Scan button will revert the
channel to its previous setting.
Automatic Scan/Set Mode: Hold the Set/Scan button. The Automatic
Scan/Set Mode will automatically scan for and set the next open channel.
5. MOUNTING ADAPTERS: For mounting the receiver in any standard 19" rack.
Attach adapters to the receiver with the screws supplied and remove the
four receiver feet. (Use optional AT8630 joining-plate kit to mount two
ATW-R2100 receivers side-by-side.)
See Figure C-Receiver LCD Window Display
6. RF SIGNAL LEVEL INDICATOR: Shows the strength of the RF signal received
from the transmitter.
7. TUNER OPERATION INDICATOR: Indicates which Tuner (A or B) has the better
reception and is in operation.
8. CHANNEL DISPLAY: Shows which channel is selected.
9. AF LEVEL INDICATOR: Shows the audio modulation level of the received signal.
See Figure D-Rear Panel Controls and Functions
10. ANTENNA INPUT JACK : BNC-type antenna connector for "B". It provides + 12 V
DC output on their centre pins to power in-line RF devices. 20mA can be drawn
from the "B" jack. See the "antennas" section on page 5 for more details.
11. SQUELCH CONTROL: Adjusts level of noise-muting circuit (preset at factory
but can be adjusted as circumstances warrant). Factory setting is full
counterclockwise.
12. ANTENNA INPUT JACK : BNC-type antenna connector for "A". It provides + 12 V
DC output on their centre pins to power in-line RF devices. 20mA can be drawn
from the "A" jack. Attach the supplied antenna directly, or extent it to an accessory
antenna with a low-loss antenna cable.
13. AF LEVEL CONTROL: Adjusts audio output level of both AF output jacks;
maximum output is fully clockwise.
14. GROUND LIFT SWITCH: Disconnects the ground pin of the balanced output
jack (15) from ground. Normally, the switch should be to the left (ground
connected). If hum caused by a ground loop occurs, slide switch to the right
(ground lifted).
15. BALANCED AUDIO OUTPUT JACK: XLRM-type connector. A standard 2-
conductor shielded cable can be used to connect the receiver output to a
balanced microphone-level input on a mixer or integrated amplifier.
16. UNBALANCED AUDIO OUTPUT JACK: 1/4" phone jack. Can be connected to
an unbalanced aux-level input of a mixer, guitar amp or tape recorder.
17. POWER INPUT JACK: Connect the DC plug from the included in-line
AC adapter.
18. CORD HOOK: Loop the small DC cord around the cord hook to keep the DC
plug from pulling out accidentally.

Battery Selection
Two 1.5V AA alkaline batteries are recommended.
UniPak™ Transmitter Battery Installation
See Figure E-UniPak Transmitter Open
1. Open the transmitter door by pressing gently on the side-cover indentations
and pulling back the hinged cover shown in Fig. E below.
2. Lift the battery-keeper arm, and carefully insert two fresh 1.5V AA alkaline
batteries, observing correct polarity as marked inside the battery
compartment.
3. Close the battery-keeper arm.
4. Close the transmitter door.
Handheld Transmitter Battery Installation
See Figure F-Handheld Transmitter Battery Compartment
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
See Figure G-UniPak Transmitter Top View and
Figure H-Handheld Transmitter Bottom View
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
See Figure G-UniPak Transmitter Top View
Connect an audio input device (microphone or guitar cable) to the audio input connec-
tor 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 9).
UniPak Transmitter Antenna
See Figure G-UniPak Transmitter Top View
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.
