Follow all warnings placed on the unit and adhere to the operating and use instructions. Retain this manual for future reference. 1.Power sources - Connect the unit to a power source only of the type described in the operating instructions or as marked on the appliance. 2.Power-cord protection - Route all power-supply cords so that they are not walked on or pinched by items placed upon or against them. 3. Grounding - Take precautions so that the grounding or polarization means of the unit are not defeated. 4.Ventilation - Position the unit so that its location does not interfere with ventilation. To maintain good ventilation, do not put items on or over the unit. Do not use the unit on a cushioned surface that may block the ventilation openings. 5. Water and moisture - Do not locate the unit near water. 6. Temperature - The unit may not function properly if used at extreme temperatures. The ideal temperature is 41oF (5 o C) to 87 o F (30 o C) 7.Heat - The unit should be located away from heat sources such as radiators, heat registers, stoves, etc. 8. Electric shock - Care should be taken so that objects do not fall and liquid is not spilled on the enclosure. If a metal object, such as a hairpin or a needle, comes in contact with the inside of this unit, a dangerous electric shock may result. 9.Enclosure removal - Never open the enclosure.

Operational Description

LCS FOUR CHANNEL TRANSMITTER BLOCK DIAGRAM VOLUME CONTROL STEREO MODULATOR VCO L R POWER AMPLIFIER LPF ANTENNA 38 KHZ OSC 4 MHZ REF 0SC 902-928 MHZ CONTROLSLCD DISPLAYPOWER SUPPLY 4MHZ CLOCK PROCESSOR - ADC LEVEL Ξ£ POWER SWITCH ANTENNA RESISTANCE SENSE VCO 902-928 MHZ VOLUME CONTROL STEREO MODULATOR L R CHANNEL # 1 CHANNEL # 4 LCS TRANSMITTER DESCRIPTION The transmitter is a four channel stereo FM transmitter operating in 902 - 928 Mhz frequency band. Microcontroller controls all the functions - reading the keypad, setting the volume (modulation depth), loading the synthesizers and displaying the channel number, volume settings and audio signal levels. Stereo audio signal from the audio source after the volume control circuitry goes to stereo modulator and then to synthesized VCO. Four modulated RF signals from VCO’s combined together and amplified by the power amplifier. Following the amplifier is the low pass filter which supress high order harmonics of the transmitted signal. Antenna is the modification of a resonant quarter-wavelength monopole with coax cable. The transmitter is powered by 120 VAC and is grounded by the standard three conductor power cord.
