Operations 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 Notice : The changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the 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 the device. 1. Introduction Thank you for purchasing our product. This wireless microphone system operates in UHF band frequency with synthesizer controlled. The system with 16 or 64 selectable frequencies via Phase Locked Loop (PLL) circuitry makes it easy to choose non-interfered channels. Please read this instruction manual carefully before operating the system. This manual covers the configuration and operation of the wireless microphone system. 2. Safety ÿ Do not spill liquid on the appliance and do not drop it on a hard concrete floor. ÿ Do not place the appliance near heat sources such as radiators, amplifier, or etc. Do not expose it to direct sunlight, extremely dust, excessive moisture, or vibration. ÿ Take out the battery from transmitter, if the appliance has been not used for a longer period. This will avoid the damage resulting from a defective leaking battery 3. Environment ÿ Do not throw used batteries into a fire or garbage bin with domestic rubbish. Be sure to dispose of used batteries in accordance with local waste disposal rules. ÿ When disposing the equipment, remove the batteries, separate the case, circuit boards, and cables, and dispose of all components in accordance with local waste disposal rules. 4. Wireless Note ÿ Before setting up, make sure that the transmitter and receiver are tuned to the same frequency. ÿ Do not use two transmitters in the same frequency. ÿ Use good quality batteries to avoid the damage resulting from a defective leaking battery. ÿ To avoid interference, do not put the receiver too near metal object and avoid obstructions between transmitter and receiver. ÿ Avoid the interference from TV, radio, other wireless appliances and etc. Wireless Microphone 2 5.

UHF 64 preprogrammed selectable frequencies to avoid interference. Uni-directional dynamic or uni-directional condenser capsules with different characters for various choices. Use 1.5V x 2 AA size batteries for low operating cost. 1. Grille: Protects the microphone capsule and helps reduce breath sounds and wind noise. The grille for the various microphone capsules differ in appearance. 2. Low Battery LED: LED indicates battery life status. Switching the power to "ON", the LED flashing once indicates that the transmitter has sufficient power. If the LED stayed on, it indicates that the battery has insufficient power and should be changed soon. If the status LED fails to flash, the battery is either dead or not positioned correctly, and you should correct the positioning or change the battery. 3. On/off Switch: Turns transmitter power on and off. 4. Battery Compartment: Insert two AA dry or rechargeable batteries into the compartment and make sure that the polarity of batteries is correct. 5. Group Selector: Changes transmitter Group setting. 6. Channel Selector: Changes transmitter Channel setting. 7. Battery Cover: Unscrew to expose battery compartment and Group/Channel selector. 8. Color Clip: This color clip helps to mark the same frequency of receiver and transmitter. 9. Charging Input: for charging rechargeable batteries inside the battery compartment using the using a supplied cable with 1.5j DC plugs. It needs up to 10 hours for charging.

The bodypack transmitter operates in UHF band frequency with PLL synthesized control. UHF 64 preprogrammed selectable frequencies to avoid interference. Uni-directional condenser capsules with different characters for various choices. Use 1.5V x 2 AA size dry or rechargeable batteries for low operating cost.

UT-18 MODULE PROCEDURE 1. Audio from the microphone is coupled through IC BA4510 applied to Audio amplifier and buffer stage. Adjust VR R66 to control audio amplify level. 2. The RF signal of 682.375MHz to 697.125MHz is generated from VCO and is locked via PLL IC U5 when selected. Adjust VC C60 to correct the exact frequency.. 3. The locked RF signal is coupled to buffer （ Q10 ） and amplifiers （ Q8 & Q9）. 4. After RF pre-amplify and final amplify, adjust VCs C67 & C68 to filter the spurious and harmonics and have the correct frequency pass through the maximum pass-point of the filter to transmit out. At this stage, the RF level is about 7dBm. MASCOT ELECTRIC CO,LTD DROW：Sherwin Liu CHECK： APPROVE： DATE ： MAY 28 2003
