SA-HT640WPL 1 Safety Precautions 1.1. GENERAL GUIDELINES 1. When servicing, observe the original lead dress. If a short circuit is found, replace all parts which have been overheated or damaged by the short circuit. 2. After servicing, see to it that all the protective devices such as insulation barriers, insulation papers shields are properly installed.
Page 6
SA-HT640WPL If this occurs, follow the procedure outlines below: 1. Turn off the power. 2. Determine the cause of the problem and correct it. 3. Turn on the power once again after one minute. Note: When the protection circuitry functions, the unit will not operate unless the power is first turned off and then on again.
SA-HT640WPL 2 Prevention of Electro Static Discharge (ESD) to Electrostatically Sensitive (ES) Devices Some semiconductor (solid state) devices can be damaged easily by static electricity. Such components commonly are called Electrostatically Sensitive (ES) Devices. Examples of typical ES devices are integrated circuits and some field-effect transistors and semiconductor "chip"...
SA-HT640WPL 3 Precaution of Laser Diode CAUTION: This unit utilizes a class 1 laser. Invisible laser radiation is emitted from the optical pickup lens. Wavelength: 662nm(DVD)/785nm(CD). Maximum output radiation power from pickup: 100µW/VDE When the unit is turned on: 1. Do not look directly into the pick up lens.
SA-HT640WPL 5 Handling Precautions for Traverse Unit The laser diode in the optical pickup unit may break down due to static electricity of clothes or human body. Special care must be taken avoid caution to electrostatic breakdown when servicing and handling the laser diode.

SA-HT640WPL 8.2.1. Operation RF signal transmission and reception: During the receive process, the radio signal is taken from a pair of balanced RF I/O pins that feed into the low noise amplifier (LNA). Direct I/Q down conversion and on-chip filtering send the processed I/Q data to the analog-to-digital converter before processing by the GFSK (Gaussian Frequency Shift Keying) demodulator.
Page 21
SA-HT640WPL Does the system support any mode to save power consumption? Yes, it has POWER SAVING SCAN mode. When the communication link is lost, the slave starts scanning procedure to re-establish the link. If the slave cannot find the master within a certain amount of time (info stored in EEPROM), the slave automatically goes into power saving scan mode.
Page 22
SA-HT640WPL How can Master or Slave setting be selected? By software or hardware? It can be selected by external control pin. How long does it take to transmit single packet? To establish communication channel properly, hopping frequency and Syncword of each packet should be determined by Device ID(Identification).
SA-HT640WPL 8.3. Class-D Amplifier 8.3.1. How are digital amplifiers different? A digital amplifier incorporates a switching output stage that operates according to a principle known as pulse width modulation (PWM). In contrast to the low-frequency control signal used in a conventional analog amplifier output stage, the switching output stage of a digital amplifier is controlled by a high-frequency digital signal.
Page 24
SA-HT640WPL 8.3.5. What are the potential problems of a Class-D amplifier based system? The two most common issues of class-D amp system are AM interference and EMI. The switching frequency of class-D ranges from 300kHz to 450kHz typically 315kHz. The harmonics of such switching frequency will fall into the AM band of 600kHz to 1710kHz.
Page 25
SA-HT640WPL Class-D amp systems are basically switching systems. As such, it is prone to EMI. EMI issues can be rectified through proper grounding techniques and proper components layout. It is quite common to see ferrite beads, capacitors and inductors on these systems.
