Model No. WRT-8P Serial No. _____________________ 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. This equipment should be installed and operated with minimum distance 20cm between the radiator and body (excluding extremities: hands, wrists and feet). 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 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. The WRT8P has been tested and found to comply with the Federal Communications Commission (FCC) guidelines on radio frequency energy (RF) exposures. 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 nointerference, no-protection 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” Table of Contents • • • • • • • • • • Overview (Features) Precautions Parts Identifications Power Supply Settings Initialing setting mode Setting the transmission channel Setting the attenuation level of the audio input Setting the RF output power Setting the +48V power supply Attachment and installation procedures Notes on microphone system operations System Configurations Error Messages Specifications ---- 5 ---- 5 ---- 6 ---- 9 ---- 10 ---- 13 ---- 14 ---- 15 ---- 16 ---- 17 Overview The WRT-8P is a plug-on transmitter for a UHF synthesized wireless microphone system to be used for broadcast or movie production purpose.

For details of operation with two or more channels, refer to the Operating Instructions for the WRR802/805/855/862, or WRU-8N with MB-8N, etc. • Ensure that the tuners set to channels not being used are either turned off or set to the minimum output level. • • • To prevent noise generation, set the RF power output to L (50 mW) when multiple channels are used simultaneously, and keep the microphones and transmitters at least 6 m (20 feet) away from the antennas when the system is operated using a group which allows selection of up to 8 channels, and at least 12 m (40 feet) away when using a group which allows selection of 9 channels. • When there is a strong interference signal around the microphone system, such as an interference caused by an active handy phone, noise may occur on the microphone system. • Before to be attached or removed the microphone or cable, turn down the volume of the equipment connected to the tuner. Otherwise, noise will be produced. When powering the transmitter on or off, to keep the noise to a minimum, set the audio output level from the tuner or mixer to a minimum. Powering the transmitter on without checking the channel selection first may interfere with the operation of other microphones/transmitters, if the current setting is already being used. 14 System Configurations Example of typical system Microphone F-112 Portable mixer Microphone DMX-P01 ECM-678 ECM-674 Plug-on transmitter WER-8P Portable tuner WRR-855B WRR-861B WRR-862B Portable tuner WRR-861B WRR-862B Portable mixer DMX-P01 Camcorder PDW-530/530P/510/510P 15 When a problem occurs, one of the following error message may appear on the display. 16 Specifications Transmitter and modulator section Oscillator Carrier frequencies Operating frequency band RF power output Tone signal Battery condition signal Pre-emphasis Deviation Maximum deviation Audio input attenuation Audio input pad Frequency response Signal-to-noise ratio Crystal controlled PLL synthesizer 758.125-781.875MHz (U6264 model) 782.125-805.875MHz (U6668 model) 24 MHz 250 mW/50 mW 32.768 kHz 32.782 kHz 50 µs +/- 10 kHz (–60 dBV, 1 kHz input, MIC) +/- 10 kHz (-18 dBu, 1 kHz input, LINE) +/- 40 kHz 0 to 20 dB (MIC, LINE) 40dB(LINE) 50 to 18,000 Hz 60 dB or more (A-weighted, modulation frequency 1 kHz, with +/- 10 kHz deviation at tuner) Power section Power requirements Battery life 9.0 V DC (one 6LR61, alkaline battery) Approx. 2.5 hours at 25°C(77° F ) with Sony 6LR61 alkaline battery (250 mW) Approx. 4 hours at 25°C(77° F ) with Sony 6LR61 alkaline battery (50 mW) General Operating temperature Storage temperature Dimensions Mass 0 C to 50 °C (32 ° F to 122 ° F) -30 °C to 60 °C(-22 ° F to 140 ° F) 44 x 106 x 44 mm (w/h/d) Approx. 230 g (including battery) Supplied accessories Operating Instructions (1) Sony Wireless Microphone System Frequency List (1) Soft case (1) Design and specifications are subject to change without notice. 0 dBV = 1 Vrms 17 Specifications UHF SYNTHESIZED TRANSMITTER5 Model.
