Note:

1. RTL (Retention Time Limited)

The “RTL” marking indicates that its Retention Time is
Limited.
When production is discontinued, this item will continue to
be available only for a specific period of time.  This period
of time depends on the type of item, and the local laws
governing parts and product retention.
At the end of this period, the item will no longer be avail-
able.

2. Important safety notice

Components identified by the   mark indicates special
characteristics important for safety. When replacing any
of these components, only use specified manufacture's
parts.

3. The S mark means the part is one of some identical parts.

For that reason, it may be different from the installed part.

4. ISO code (Example: ABS-94HB) of the remarks column

shows quality of the material and a flame resisting grade
about plastics.

5. RESISTORS & CAPACITORS

Unless otherwise specified;
All resistors are in ohms (

Ω), k=1000Ω, M=1000kΩ

All capacitors are in MICRO FARADS (

µF), p=µµF

*Type & Wattage of Resistor
