Important Safety Instructions
Please read and keep these instructions.
CAT-5e CABLE SAFETY
CAUTION!
Do NOT plug the WIR TX75 (master) CAT-5e / RJ45 cable into anything other than the WIR TX75-S slave(s). The TX75 CAT-5e / RJ45 connection is proprietary and is NOT compatible with ethernet or any other RJ45 systems. Failure to comply with this caution can destroy this or other equipment and will void the warranty.
Receiver Safety Warnings
HEARING SAFETY
CAUTION!
Many Williams Sound receivers are designed to amplify sounds to a high volume level, which could potentially cause hearing damage if used improperly. To protect your hearing and the hearing of others:
1. Make sure the volume is turned down before putting on the earphone or headphone—only then adjust the volume to a comfortable level.
2. Set the volume level at the minimum setting that you need to hear.
3. If you experience feedback (a squealing or howling sound), reduce the volume setting and move the microphone away from the earphone or headphone.
4. Do not allow children or other unauthorized persons access to this product.
BATTERY SAFETY AND DISPOSAL
CAUTION!
Williams Sound receivers are supplied with non-rechargeable alkaline batteries. Do not attempt to recharge non-rechargeable batteries; they may explode, release dangerous chemicals, cause burns, or cause other serious harm to the user or product.
PACEMAKER SAFETY
CAUTION!
If you have a pacemaker or other medical device, make sure that you are using the Williams Sound receiver in accordance with safety guidelines established by your physician or the pacemaker/medical device manufacturer.
Transmitter Safety Warnings

Servicing or attempting to service this device will void the warranty
Refer servicing to qualied personnel. Servicing is required when the system has been damaged in any way: if liquid has been
spilled or objects have fallen into the unit, if the unit has been exposed to moisture, if the unit does not operate normally, or if the unit has been dropped.
Do not block any ventilation openings. Install in accordance with manufacturer’s instructions.
Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus that produces heat.
Use only attachments/accessories specied by the manufacturer.
Unplug the transmitter during lightning storms or when unused for long periods of time.
Be advised that different operating voltages require the use of different types of line cord and attachment plugs. Check the voltage in your area and use the correct type.
Use only the power supply provided by Williams Sound. Other power supplies may have similar specications, but may not
be equivalent in emissions ratings, in-rush current, etc. Use of an unapproved power supply may leave the device partially or completely inoperable, and will void the warranty.
This apparatus has been designed with class-1 construction and must be connected to a main socket outlet with a protective ground connection (the third grounding prong).
Protect the power cord from being walked on or pinched, particularly at plugs, receptacles, and near the power jack on the transmitter.
This apparatus must be grounded.
The MAINS plug or an appliance coupler is used as the disconnect device, so the disconnect device should remain readily operable.
For Customers in The United States
WARNING: Use a three-wire grounding-type line cord as is supplied with the product. Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has two blades with one wider than the other. A grounding type plug has two blades and a third grounding prong. The wide blade or the third prong is provided for
your safety. If the provided plug does not t into your outlet, consult an electrician for replacement of the obsolete outlet. This equipment has been tested and found to comply with the limits for Class B digital device, pursuant to part
15 of the FCC rules.
For Customers in Canada
This Class B digital device meets all requirements of the Canadian Interference-causing Equipment Regulations.
Cet appareil numérique de la classe B respecte toutes les exigencies du Règlement sur le matériel brouilleur du Canada.

WIR TX75 Two-Channel Infrared Transmitter
System Overview
The WIR TX75 two-channel infrared transmitter combines infrared modulator and emitter technology into a single mountable enclosure—which reduces operating costs, eliminates the need for rack space and eases set-up.
The WIR TX75 is ideal for high-quality audio programs such as music, theater and audio description. The WIR TX75 will accept any line level, balanced or unbalanced audio inputs. Infrared receivers detect the transmission and convert the light signals back
into audio signals. The 2.3/2.8 MHz (or 3.3/3.8 MHz for TX75b) operating frequencies minimize high-efciency lighting interference.
Up to two slave emitters can be added for additional coverage. Power, baseband, and digital data are fed to the slave emitters via a single CAT-5e cable for each emitter. No additional cables are required.
No FCC license or radio approval is required with this equipment. It can be used anywhere in the world.
NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15
of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area may cause interference in which case the user will be required to correct the interference at his own expense.
NOTE: A PLASMA MONITOR OR TELEVISION CAN DEGRADE THE AUDIO QUALITY OF THE WIR TX75 TRANSMITTER. FOR
BEST PERFORMANCE, THE TRANSMITTER SHOULD BE POSITIONED AS FAR AWAY AS POSSIBLE FROM ANY PLASMA MONITOR OR TELEVISION.
