This device complies with part 15 of the FCC Rules. Operation is subject to the condition that this device does not cause harmful interference.

This device complies with INDUSTRY CANADA R.S.S. 210, en conformité avec IC: RSS-210/CNR210.

Operation is subject to the following conditions: 1) This device may not cause harmful interference and 2) this device must accept any interference

received, including interference which may cause undesired operation. Changes or modifications not expressly approved by Audio-Technica could

void your authority to operate this equipment.

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 medical-device 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.

Warning: To prevent fire or shock hazard, do not expose this appliance to rain or moisture.
Attention: Pour prévenir feu ou choc électrique, ne pas exposé l'appareil à la pluie ou à l'humidité.

About RF Interference

Please note that wireless frequencies are shared with other radio services. According to Federal Communications Commission regulations,

“Wireless microphone operations are unprotected from interference from other licensed operations in the band. If any interference is received

by any Government or non-Government operation, the wireless microphone must cease operation...”

If you need help with operation or frequency selection, please cont act your local dealer or Audio-Technica. Extensive wireless information

Quick Overview of System Operation

Thank you for purchasing this Audio-Technica 1800 Series Single-channel Camera-mount
UHF Wireless Microphone System. All 1800 Series Single-channel systems are designed

primarily to be used with video cameras, with the ATW-R1810 Receiver mounted on a camera

and connected to the camera's audio input; they may also be used with other components

equipped with microphone-level input.

First, insert batteries. (See Receiver Battery Installation, page 8.) Note:The ATW-R1810 Single-

channel Receiver also functions without batteries if connected to an external power sup­ply (12V DC source, 500 mA nominal current, not included).

Next, attach the antennas to the antenna input jacks, and mount the AT W-R1810 Receiver to your

camera (mounting hardware not included); or use the included pouch with belt clip to attach the

AT W-R1810 to your belt. Connect the output cable to the AT W-R1810 and your video camera (or

audio mixer). (See Output callout, page 7 ).

Turn the ATW-R1810 on: Press and hold the Power/Set button until the Power LED lights red.

Select an operating frequency. (See Selecting Frequencies on your Receiver, page 9.)

NOTE:Transmitter-Receiver pairs must be set to identical frequencies.

IF your system is equipped with a UniPak®Body-pack Transmitter and lavalier microphone:

Plug the included lavalier microphone into the UniPak®body-pack transmitter and position

microphone on your subject about six inches below the chin. Anticipate movements that may

cause the microphone to rub against or be covered by clothing, and position the microphone to

avoid it. Turn the power on (See Operating the Transmitter, page 11). Select a frequency and

choose other settings. (See Operating the Transmitter and How to Set Frequencies on your

Transmitter, page 11.)

IF your system is equipped with a Plug-onTransmitter: Attach a microphone (dynamic or con-

denser) to the Plug-on Transmitter's input connector (See Microphone Input, page, 10). Turn

the power on (See Operating theTransmitter, page 11). Select a frequency and choose other set-

tings. (See Operating the Transmitter and How to Set Frequencies on your Transmitter, page 11.)

RF power may be set to “RF HI” (30 mW nominal) or “RF LOW” (10 mW nominal) through the
function menu. The default setting is “RF LOW”. While the High setting normally provides
maximum operating range, the Low setting will help extend battery life. The Low setting may
also be preferred in multichannel systems, or when operating very close to the receiver, to
reduce the possibility of interference or receiver RF overload.

Correct adjustment of transmitter audio input, receiver audio output, and mixer/amplifier input
and output levels is important for best performance.

A 5-position audio input gain setting, selected through the function menu, allows you to match
the audio input level to the transmitter for best modulation with minimum distortion. The choices
are +18, +12 dB, +6 dB, 0 dB and -6 dB. The default value is +6 dB. Select the highest setting
that does not result in over-modulation with the highest audio /instrument input levels (an AF
indication on the receiver no higher than “0”).

Using the Mute and Un-Mute Functions

on yourTransmitter

Power/Mute Locks

Audio Input Selector

When the transmitter is muted, it produces RF with no audio. When the transmitter is
un-muted, it produces both RF and audio. To mute the transmitter (cut off the audio, but
continue the RF output), press and release the Power/Mute button once. The word “MUTE” will
appear in the LCD window, just below the frequency, and the Power-on LED will turn red.
To un-mute the transmitter (restore the audio), press and release the Power/Mute button once
again. The “MUTE” will disappear from the LCD window, and the Power-on LED will turn green.

The Power/Mute button can be programmed (through the function menu): power can be locked
On; Mute can be locked either On or Off.

Setting Description

NO.LOC The Power and Mute functions operate normally.
ALL.LOC Both the Power and Mute functions are locked into their status as of the time

“ALL.LOC” is applied. (Power On, and Mute either On or Off.) Note: “ALL.LOC”

must be re-accessed and the setting changed to turn the transmitter off.

MUT.LOC In “MUT.LOC” mode, the audio cannot be muted. The Power functioning is

unaffected. (If “MUT.LOC” is applied while the transmitter is muted, pressing the
Power/Mute button once will return to un-muted operation; thereafter the Mute
function is disabled until the setting is changed again.)

PWR.LOC Power is locked On as of the time “PWR.LOC”is applied. The Mute functioning

is unaffected. Note: When in the “PWR.LOC” mode, the transmitter may be

turned off by: (1) Re-accessing the .LOC Menu and changing the setting, or
(2) Removing and re-installing the batteries. When the transmitter is
turned on again, it will power-up in the“NO.LOC” mode. (Only the “PWR.LOC”

function will change when batteries are removed; all other settings remain stored
in memory.)

If an attempt is made to take an action that currently is locked out, the LCD will
display “LOC.KED” briefly, then return to its previously-displayed contents.

The UniPak®body-pack transmitter provides input connections for both low-impedance (Lo-Z)
microphones and high-impedance (Hi-Z) instruments. A wide range of Audio-Technica Wireless
Essentials™microphones and cables are available pre-terminated with the appropriate
professional latching connector (see page 13 ).

Tips for Best Results

1. Use only fresh alkaline batteries. Always replace all batteries.
Do not use “general purpose” (carbon-zinc) batteries.

2. Position the receiver so that it has the fewest possible obstructions between it and the
normal location of the transmitters. Line-of-sight is best.

3. The transmitters and the receiver should be as close together as conveniently possible, but
no closer together than three feet.

4. The receiver antennas should be in the open and away from any metal.

5. Each transmitter-receiver pair must be set to the same frequency.

6. When using multiple systems, only one transmitter on a given frequency should be “on” at
a time.

7. If the “Out Level” of the receiver is set too high, it may over-drive the input of the
camera/mixer or clip the output of the receiver, causing distortion. Conversely, if the receiver
output is set too low, the overall signal-to-noise ratio of the system may be reduced.

8. You need to change channels 1) when a strong interference signal is received, 2) when the
channel breaks down, or 3) during multiple-system operation in order to select an interference­free channel. Always turn the units off before changing frequencies.

9.Turn the receiver and transmitter off when not in use. Remove the batteries during long-term storage.
