1 Safety Precaution 1.1. General Guidelines 1.3. Leakage Current Hot Check (See Figure 1.) 1. IMPORTANT SAFETY NOTICE There are special components used in this equipment 1. Plug the AC cord directly into the AC outlet. Do not use which are important for safety. These parts are marked by an isolation transformer for this check.
2 Warning 2.1. Prevention of Electrostatic Discharge (ESD) to Electrostatically Sensitive (ES) Devices Some semiconductor (solid state) devices can be damaged easily by static electricity. Such components commonly are called Elec- trostatically Sensitive (ES) Devices. Examples of typical ES devices are integrated circuits and some field-effect transistors and semiconductor "chip"...
2.3.2.3. How to Replace the Fuse A replacement fuse cover can be purchased from your local Panasonic Dealer. 1. Remove the Fuse Cover with a screwdriver. If the fitted moulded plug is unsuitable for the socket outlet in your home then the fuse should be removed and the plug cut off and disposed of safety.
NOTE: This Lithium battery is a critical component. (Type No.: ML-614S/ZTK Manufactured by Energy Company, Panasonic Corporation.) It must never be subjected to excessive heat or discharge. It must therefore only be fitted in requirement designed specifically for its use.
3 Service Navigation 3.1. Introduction This service manual contains technical information, which allow service personnel’s to understand and service this model. Please place orders using the parts list and not the drawing reference numbers. If the circuit is changed or modified, the information will be followed by service manual to be controlled with original service manual. 3.2.
3.3. How to Define the Model Suffix (NTSC or PAL model) There are seven kinds of SDR-SW21. • a) SDR-SW21P • b) SDR-SW21PC • c) SDR-SW21EB/EC/EF/EG/EP • d) SDR-SW21EE • e) SDR-SW21GN • f) SDR-SW21GK • g) SDR-SW21PU/GC What is the difference is that the “INITIAL SETTING” data which is stored in Flash ROM mounted on Main PCB.
5 Service Fixture & Tools 5.1. When Replacing the Main PCB After replacing the MAIN PCB, be sure to achieve adjustment. The adjustment instruction is available at “software download” on the “Support Information from NWBG/VDBG-AVC” web-site in “TSN system”, together with Maintenance software. 5.2.

Therefore, handle the value indicated on here as reference. SDR-SW21EG SDR-SW21PC SDR-SW21EP SDR-SW21PU 6.Use the parts number indicated on the Replacement Parts List .
S2. Voltage Chart Note) Indicated voltage values are the standard values for the unit measured by the DC electronic circuit tester (high-impedance) with the chassis taken as standard. Therefore, there may exist some errors in the voltage values, depending on the internal impedance of the DC circuit tester. S2.1.
S6. Replacement Parts List Note: 1.* Be sure to make your orders of replacement parts according to this list. 2. IMPORTANT SAFETY NOTICE Components identified with the mark have the special characteristics for safety. When replacing any of these components, use only the same type. 3.
