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 å la pluie ou å Ilhumidité. 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 contact your local dealer or Audio-Technica.

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. Audio Input Level (Gain) Adjustments Correct adjustment of transmitter audio input, receiver audio output, and mixer/amplifier input on your Transmitter 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 Using the Mute and Un-Mute Functions When the transmitter is muted, it produces RF with no audio. When the transmitter is on your Transmitter 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. Power/Mute Locks 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 NOLOC The Power and Mute functions operate normally. ALL. LOC Both the Power and Mute functions are locked into their status as of the time MUT.LOC PWR.LOC "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. 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.) 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 tumed 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. Audio Input Selector 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 EssentialsTM microphones and cables are available pre-terminated with the appropriate professional latching connector (see page 13). Select the desired input — microphone or instrument — through the function menu; " MIC" or "INST" will show in the LCD window, just below the frequency.

Press the Set button once to exit the Menu mode and return to normal operation, with all factory-default settings restored. Tips for Best Results Use only fresh alkaline batteries. Always replace all batteries. 1. Do not use "general purpose" (carbon-zinc) batteries. Position the receiver so that it has the fewest possible obstructions between it and the 2. 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. Each transmitter-receiver pair must be set to the same frequency. 5. 6. When using multiple systems, only one transmitter on a given frequency should be "on" at a time. If the "Out Level" of the receiver is set too high, it may over-drive the input of the 7. 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 interference- free 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. ****** Page 14 ****** 14 ****** Page 15 ****** Specificationst UHF Operating Frequencies Band C: Band D: Number of Operating Frequencies Frequency Stability Modulation Mode Normal Deviation Operating Range Operating Temperature Range Frequency Response Receiving System Image Rejection Signal-to-Noise Ratio Total Harmonic Distortion Sensitivity Audio Output (balanced) Output Connector Monitor Headphone Output (typical) Monitor Headphone Jack External Power Requirements Batteries (not included) Current Consumption (battery) Battery Life Dimensions Net Weight (without batteries) Accessories Included RF power Output Spurious Emissions Dynamic Range Input Connections Batteries (not included) Current Consumption Battery Life Dimensions Net Weight (without batteries) RF Power Out ut Spurious Emissions Dynamic Range Input Connector Microphone Power Batteries (not included) Current Consumption Battery Life Dimensions Net Weight (without batteries) 541.500 to 566.375 MHz 655.500 to 680.375 MHz 996 total per band (25 kHz increments) Phase Lock Loop frequency control FM 100 m (300') typical 230 F (-50 C) to 1130 F (450 C) 70 Hz to 15 kHz Dual independent RF sections. automatic-switching diversity 104 dB at 30 kHz deviation (A-weighted), maximum modulation 37 kHz 105 dB, A-weighted High impedance, low impedance, bias Two 15V AA alkaline Approximately 6 hours (High); 8 hours (Low), depending on battery type and use pattern 66.0 mm (2.60″) W x 87.0 mm (3.43″) H x 24.0 mm (0.94″) D 80 grams (2.8 oz) Hi h: 30 mW; Low: 10 now, nominal Under federal regulations > 105 dB, A-weighted 3-pin locking XLRF-type Provides power to condenser microphones rated to operate on 12V phantom power or less.
