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 an active gas, clean its surface as well as the connectors with a dry, soft cloth soon after use. Lengthy use of the unit 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 factory adjusted precisely. Do not tamper with its internal parts or attempt to repair it. • Do not attempt to recharge an alkaline battery. • Do not dispose of a battery in fire. Do not disassemble or short-cirtuit a battery. • Make sure to use an L6 (size-AA) alkaline battery. • Make sure the poles of the battery match the + and - markings in the battery holder. • Remove the battery when the unit will not be used for a long period of time. 4 US Introduction The WRT-807A is a UHF-synthesized wireless microphone for use in a 800-MHz band UHF-synthesized wireless microphone system. The WRT-807A operates in conjunction with the WRR- 800A/801A/802A/805A, MB-806A UHF Synthesized Tuner for vocal concentration. The WRT-807A can be also used with existing Sony wireless microphone systems consisting of the WRT-810A/ 820A/822A/830A UHF Synthesized Transmitter and WRR- 810A/820A/840A/850A, MB-806A UHF Synthesized Tuner. The microphone/transmitter and tuners of the wireless microphone system are classified by frequency band. A 12 MHz frequency band (or two consecutive-numbered TV channels, such as 68 and 69 of the U68 model) is assigned to each microphone/transmitter and tuner model. In building up a UHF wireless microphone system, be sure to combine a microphone/transmitter and a tuner having the same TV channel number. For the selectable wireless channels and frequencies, see “Wireless Channel Lists” on page L-1. Features Phase Locked Loop (PLL) synthesized system The WRT-807A features a refined phase locked loop (PLL) synthesizer circuit. POWER switch with holding function The POWER switch can be locked in the ON position to protect against accidental power cut-offs. Low-battery notification on tuner When the microphone battery is low, the microphone sends a warning to the WRR-800A/801A/802A/805A/850A, MB- 806A in the form of “Battery status information.” This information is sent to the WRR-800A/801A/802A/ 805A/850A, MB-806A about one hour before the battery goes dead to allow the battery to be safely replaced. When the WRR-800A/801A/802A/805A/850A, MB-806A receives this information, the LED and the LCD on tuner panel start to flash. Powered by readily available battery type The built-in, high-efficiency DC-DC converter provides about five hours of continuous and stable operation with just a single LR6 (size-AA) alkaline battery. 5 US LCD readout of various information The microphones LCD shows the current chann…

The measurement shall be made on an open field test site which is free from reflecting objects that may affect the measurement results. 2.For radiated power output of the equipment, the measuring antenna was raised and lowered to obtain a maximum reading on the spectrum analyzer with the antenna vertically and horizontally polarized. The turntable was rotated a minimum of 360 degrees to further increase the reading on the spectrum analyzer. Then field strength was recorded in dBμV/m. 3.The unit was removed and replaced with a dipole antenna. (The antenna was adjusted to a half-wave of transmitting frequency.) The center of the dipole antenna was placed approximately at the same location as the center of the unit. 4.The dipole antenna at the unit end was connected to a signal generator with a coaxial cable. With the antennas at both ends vertically and horizontally polarized and signal generator tuned to the transmitting frequency, the level of the signal generator output was adjusted to the previously recorded maximum reading for this set of conditions was obtained. 5.The input power into the dipole antenna was calculated from the coaxial cable loss and the signal generator output voltage obtained in these readings. For the measured data, refer to Page 17. FCC ID: AK8WRT807A66 Page 8 2.1047 Modulation characteristics A. Measurement procedure (Acoustical Frequency Response) The test sound signal was applied to the unit in the anechoic chamber. The sound pressure level was made 94 dB constant. A Modulation analyzer was connected to the antenna and the level recorder. The test sound signal frequency was swept 50 Hz to 15 kHz and output of the modulation analyzer was recorded.
