Notice for customers in the U.S.A.

Use of Sony wireless devices is regulated by the Federal Communications Commission as described in Part 74 subpart H of the FCC regulations and users authorized thereby are required to obtain an appropriate license. You are cautioned that any changes or modifications not expressly approved in this manual could void your authority to operate this equipment.

IMPORTANT NOTE: To comply with the FCC RF exposure compliance requirements, no change to the antenna or the device is permitted. Any change to the antenna or the device could result in the device exceeding the RF exposure requirements and void user's authority to operate this device. This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment.

FCC Radiation Exposure Statement:

The available scientific evidence does not show that any health problems are associated with using low power wireless devices. There is no proof, however, that these low power wireless devices are absolutely safe. Low power Wireless devices emit low levels of radio frequency

S er i al N o .

energy (RF) in the microwave range while being used. Whereas high levels of RF can produce health effects (by heating tissue), exposure to low level RF that does not produce heating effects causes no known adverse health effects. Many studies of low level RF exposures have not found any biological effects. Some studies have suggested that some biological effects might occur, but such findings have not been confirmed by additional research.

Notice for customers in Canada:

Use of Sony wireless devices is regulated by the Industry Canada as described in their Radio Standard Specification RSS-123. A license is normally required. The local district office of Industry Canada should therefore be contacted. When the operation of the device is within the broadcast band, the license is issued on no-interference, noprotection basis with respect to broadcast signals. Operation of this device is subject to the following two conditions: (1) this device may not cause interference, and (2) this device must accept any interference, including interference that may cause undesired operation of the device. The term “IC:” before the radio certification number only signifies that Industry Canada technical specifications were met.

IC Exposure of Humans to RF Fields

The installer of this radio equipment must ensure that the antenna is located or pointed such that it does not emit RF field in excess of Health Canada limits for the general population; consult Safety Code 6, obtainable from Health Canada's website: www.hc-sc.gc.ca/rpb.

Overview

Precautions

The WRT-8P is a plug-on transmitter for a UHF synthesized wireless microphone system to be used for broadcast or movie production purpose. This transmitter is suitable for ENG1) and

EFP

The microphone/transmitter and tuner of the wireless microphone system are classified by frequency band.

A 24-MHz frequency band is assigned to each microphone/transmitter and tuner model. In building a UHF wireless microphone system, be sure to combine a microphone/transmitter and a tuner having the same wireless channel (frequency).

1) ENG: Electronic News Gathering

2) EFP: Electronic Field Production

Features

The features of the WRT-8P are as follows:

• Converts a wired microphone to a wireless microphone via an XLR-type connector.

• Compact and lightweight metal body provides high durability and good balanced handling.

• 250 mW high RF output power for stable long-distance transmission.

• Selectable RF output power: 250 mW/50 mW.

• +48 V power supply for microphone.

• Switchable input level (MIC or LINE).

• Attenuator function allows adjustment of the audio input level.

• An LCD with a backlighting provides extensive information.

• Optimized balance when combined with the F-112 Dynamic Microphone.

• The unit is designed for use in ambient temperature range of 0°C to 50°C (32°F to 122°F).

• Do not place the unit on or near heat sources, such as lighting equipment, power amplifiers, or in a place subject to direct sunlight or excessive moisture. In such places, the external finish or internal parts of the unit may be damaged.

• If the unit is used in a very humid or dusty place or in a place subject to expose to an active or corrosive gas, clean its surface as well as the connectors with a dry, soft cloth immediately after use.

• Using the unit in extended period of time in such places or not cleaning it after its use in such places may shorten its life.

• When cleaning the unit, never use organic solvents such as thinners or benzine, which will damage the finish of the unit.

• The unit has been adjusted precisely at the factory. Do not tamper with its internal parts or attempt to repair it.
