13.1.8. TILT Motor Control Block
A Tilt motor operates, when CPU (IC101) on a main board controls the motor driver IC (IC402) on the
same board.
A Constant Voltage Bipolar Drive System is employed. The Voltage of Motor Power (VM) is 3.3V. ø15
Stepping Motors are employed.
13.1.9. LED Control Block
LED is controlled by CPU which is mounted on Main Board. Control data is input into LED Control
Circuit which is mounted on Sub Board. (Three color LED is employed.)

13.2. RF BLOCK
- Antenna
- Receiver
The receiving signal from the antenna is input to the RFIC (IC502) after being passed through the
Antenna Switch (IC506) and amplified at LNA (Low Noise Amp). The RFIC (IC502) incorporates the LNA
(Low Noise Amp), the Mixer for Frequency Converter and the Synthesizer generating the Receiving
Local Signal. At the RFIC (IC502), the input signal is separated into the baseband signals of the In-
Phase(RxI) and Quadrature (RxQ) to output.
