8. Parts Location and Replacement Parts List
Note:
- Important safety notice:
Components identified by mark have special characteristics
important for safety.
Furthermore, special parts which have purpose of fire-retardant
(resistors), high-quality sound (capacitors), low-noise (resistors),
etc. are used.
When replacing any of these components, be sure to use only
manufacturer’s specified parts shown in the parts list.
- The parenthesized indications in the Remarks 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.
- Capacitor values are in microfarads ( F) unless specified
otherwise, P=Pico-farads (pF), F=Farads.
- Resistance value are in ohms, unless specified otherwise, 1K=
1,000 (OHM).
- The marking (RTL) indicates that the Retention Time is limited for
this item. After the discontinuation of this assembly in production,
the item will continue to be available for a specific period of time.
The retention period of availability is dependant 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
MESA.
- The “(SF)” mark denotes the standard part.
