You can enjoy vivid sound which matches the zoomed up images recorded by your video camera recorder. You can also use this system with a tape recorder as a conventional wireless microphone system to record the sound. •The operational distance between the transmitter unit and the receiver unit can be up to approximately 45 m (150 feet). However, this distance may become shorter if there are some obstacles in between the transmitter unit and the receiver unit. •The radio frequency can be selected so that a less busy channel can be used while the air is busy. •Compact design featuring built-in antennas. •The transmitter unit is equipped with a plug in power∗ type MIC jack (monaural/ 3.5 mm dia.) An optional microphone other than the supplied one can be connected to this jack. •The transmitter and receiver units are equipped with clip type holders with the adjustable clips which can be rotated 360 degrees so that the transmitter and receiver units can be attached onto your clothes, etc. •The receiver unit is equipped with the MIX MIC jack to which an optional microphone such as the ECM-T145 (lavalier microphone) can be connected, so that the sound transmitted from the transmitter unit can be mixed with the sound picked up by the optional microphone. •The receiver unit is equipped with the v (earphone) jack to which the supplied earphone can be connected, so that you can monitor the sound being recorded. You can use the earphone connected to the receiver unit to monitor the subject using the transmitter unit. •The supplied lavalier microphone has a built-in wind screen effect so that you can use the microphone in the open air without a wind screen. * Plug in power system The system that power is supplied directly to the microphone from the microphone jack of the connected equipment. www. xiaoyu163. com QQ 376315150 9 9 2 8 9 4 2 9 8 TEL 13942296513 9 9 2 8 9 4 2 9 8 0 5 1 5 1 3 6 7 3 Q Q TEL 13942296513 QQ 376315150 892498299 TEL 13942296513 QQ 376315150 892498299 http://www.xiaoyu163.com 4 WCS-880 SECTION 2 DISASSEMBLY 2-2.

METAL: Metal-film resistor. METAL OXIDE: Metal oxide-film resistor. F: nonflammable • Items marked “*” are not stocked since they are seldom required for routine service. Some delay should be anticipated when order- ing these items. • SEMICONDUCTORS In each case, u: µ, for example: uA. . : µA. . uPA. . : µPA. . uPB. . : µPB. . uPC. . : µPC. . uPD. . : µPD. . • CAPACITORS uF: µF • COILS uH: µH The components identified by mark 0 or dotted line with mark 0 are critical for safety.
