This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. Any modifications made to this device that are not approved by TOA Corporation may void the authority granted the user by the FCC to operate this equipment.

FCC Compliance

When Installing the Unit

• Do not expose the unit to rain or an environment where it may be splashed by water or other liquids, as doing so may result in fire or electric shock.

• Use the unit only with the voltage specified on the unit. Using a voltage higher than that which is specified may result in fire or electric shock.

• Do not cut, kink, otherwise damage nor modify the power supply cord. In addition, avoid using the power cord in close proximity to heaters, and never place heavy objects -- including the unit itself -- on the power cord, as doing so may result in fire or electric shock.

When the Unit is in Use

• Should the following irregularity be found during use, immediately switch off the power, disconnect the power supply plug from the AC outlet and contact your nearest TOA dealer. Make no further attempt to operate the unit in this condition as this may cause fire or electric shock.

· If you detect smoke or a strange smell coming

from the unit.

· If water or any metallic object gets into the unit

· If the unit falls, or the unit case breaks

· If the power supply cord is damaged (exposure of

the core, disconnection, etc.)

· If it is malfunctioning (no tone sounds.)

• To prevent a fire or electric shock, never open nor remove the unit case as there are high voltage components inside the unit. Refer all servicing to qualified service personnel.

• Do not place cups, bowls, or other containers of liquid or metallic objects on top of the unit. If they accidentally spill into the unit, this may cause a fire or electric shock.

• Do not touch a power supply plug during thunder and lightning, as this may result in electric shock.

When Installing the Unit

• Never plug in nor remove the power supply plug with wet hands, as doing so may cause electric shock.

• When unplugging the power supply cord, be sure to grasp the power supply plug; never pull on the cord itself. Operating the unit with a damaged power supply cord may cause a fire or electric shock.

• When moving the unit, be sure to remove its power supply cord from the wall outlet. Moving the unit with the power cord connected to the outlet may cause damage to the power cord, resulting in fire or electric shock. When removing the power cord, be sure to hold its plug to pull.

• Avoid installing the unit in humid or dusty locations, in locations exposed to the direct sunlight, near the heaters, or in locations generating sooty smoke or steam as doing otherwise may result in fire or electric shock.

• Refer all installation work to the dealer from where the unit was purchased. Installation requires extensive technical knowledge and experience. Improper installation may result in personal injury or electric shock.

When the Unit is in Use

• Use the AC adapter supplied with the unit. Note that the use of other adapter may cause a fire.

• If dust accumulates on the power supply plug or in the wall AC outlet, a fire may result. Clean it periodically. In addition, insert the plug in the wall outlet securely.

• Switch off the power, and unplug the power supply plug from the AC outlet for safety purposes when cleaning or leaving the unit unused for 10 days or more. Doing otherwise may cause a fire or electric shock.

WARNING CAUTION

1. SAFETY PRECAUTIONS

• Before installation or use, be sure to carefully read all the instructions in this section for correct and safe operation.

• Be sure to follow all the precautionary instructions in this section, which contain important warnings and/or cautions regarding safety.

Indicates a potentially hazardous situation which, if mishandled, could result in moderate or minor personal injury, and/or property damage.

WARNING

CAUTION

1. Power switch

Press this switch to turn on the power. To turn off the power, press this switch again.

2. Power indicator

Lights when the power is switched on.

3. Cable Clip

Run the AC adapter cable through this clip to prevent its plug from being removed.

4. DC inlet [DC IN]

Connect the supplied AC adapter.

5. Receiver mixing input terminals [IR IN]

Connect the infrared wireless receiver or the distributor. Up to 8 infrared wireless receivers can be connected with the use of the optional YW-1022 (2-Branch Distributor) or the YW-1024 (4-Branch Distributor).

6. Distribution output terminals [IR OUT]

Connect the IR-702T Infrared Wireless Tuner.

2. GENERAL DESCRIPTION

The IR-700D is a receiver distributor used in the TOA’s infrared wireless microphone system. It employs 4 receiver mixing inputs and 2 distribution outputs. By using the IR-700D in conjunction with the IR-702T Infrared Wireless Tuner, up to 16 infrared wireless receivers can be connected to the IR-702T.

3. HANDLING PRECAUTIONS

• Install the IR-702T as far as possible from fluorescent lights, digital equipment, PCs and other devices that generate high-frequency noise.

• When cleaning, be sure to first switch off the tuner's power, then wipe with a dry cloth. If the tuner is extremely dirty, use a cloth moistened in a neutral detergent. Do not use benzene, thinner, alcohol and chemically-processed towels, as they can cause damage to the tuner's components and parts.

8. WIRING TO INFRARED WIRELESS RECEIVER

8.1. Wiring Precautions

When multiple infrared wireless receivers have received an infrared signal from the infrared wireless microphone, the reception level increases if the signals input to each receiver are in phase with each other. However, the reception level could decrease if the signals are out of phase.

• To match signal phases, make each corresponding cable the following length:

Cable length from each infrared wireless receiver to the IR-700D : M1 + N1 = M2 + N2

where M1, N1, M2, and N2 are:

M1: Length between Infrared wireless receiver (A or A’) and YW-1022/1024 Distributor (1) N1: Length between YW-1022/1024 Distributor (1) and IR-700D M2: Length between Infrared wireless receiver (B or B’) and YW-1022/1024 Distributor (2) N2: Length between YW-1022/1024 Distributor (2) and IR-700D

8.2. When Using the Distributor YW-1022/1024

• The YW-1022 is a 2-branch distributor and the YW-1024 is a 4-branch distributor.

• Some idle YW-1024 distribution terminals may result, depending on wiring, however this presents no problem.

• Avoid connecting 2 or more distributors in series. Connecting them in series increases high-frequency signal loss, potentially resulting in system malfunctions.

• Assure that all infrared wireless receivers within the same system are connected through the same type of Distributor. If different types of Distributors are mixed together, or if there are connections both through and around the Distributor, this can narrow the coverage area.

• The maximum cable length between each Infrared Wireless Receiver and IR-700D differs depending on the type of coaxial cable to be used. Take care not to exceed the maximum cable length. (Refer to p. 10 "Supplementary Remarks.")

Note

When using the YW-1022 or YW-1024 Distributors, be sure to connect the same type of distributor to the IR-700D’s receiver mixing inputs 1 – 4. No problems should result even if a different number of infrared receivers are connected to each YW-1022/1024.
