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. If the internal parts are accidentally touched, a serious shock may occur. 10.Cleaning - Do not use solvents such as alcohol, paint thinner, etc. to clean the unit. Use a clean dry cloth. 11.Abnormal smell - If an abnormal smell is detected, immediately turn the power OFF and disconnect the power cord. Contact your dealer or service center.

Seitz&AssociatesNov 19, 1999 CARDIO-THEATER SINGLE CHANNEL LOW COST SYSTEM The LCS-1 single channel Transmitter The audio stereo signal comes to electronic volume control and then to stereo modulator. Composite stereo signal is then used for direct FM modulating the VCO at 905 - 925 MHz. Signal from VCO then goes to power amplifier and harmonic suppression filter and after amplification goes to antenna. The PIC microcontroller and EEPROM provides all controls, memory and display functions. The user can program one of 52 RF channels, and volume. Clock/Oscillator Frequencies: 38 kHz, 4 MHz, 905 -925 MHz

Seitz & AssociatesDecember 6, 1999 ANTENNA REQUIREMENTS The LCS transmitter uses a special antenna which is mounted on the PCB and can not be removed without complete disassembly of the unit and in turn this will void manufacturer warranty. This insures that no other antenna will be used with the LCS transmitter.
