Furth

44、ermore, special parts which have purposes of fire-retardent (resistors), high-quality sound (capacitors), low noise (resistors), etc are used. When replacing any of these components, be sure to use only manufacturers specified parts shown in the parts list. The parenthesized indications in the Remar

45、ks columns specify the areas or colour. (Refer to the cover page for area or colour) Parts without these indications can be used for all areas. Warning: This product uses a laser diode. Refer to “Precaution of Laser Diode”. Capacitor values are in microfarads (F) unless specified otherwise, P= Pico-

46、farads (pF), F= Farads. Resistance values are in ohms, unless specified otherwise, 1K=1,000 (OHM). The marking (RTL) indicates that the Retention Time is limited for this items. After the discontinuation of this assembly in production, the item will continue to be available for a specific period of

47、time. The retention period of a availability is dependent on the type of assembly, and in accordance with the laws governing part and product retention. After the end of this period, the assembly will no longer be available. M Indicates in the Remarks columns indicates parts supplied by PAVCSG. Refe
