1.3. Replacing the Fuse

Use fuses of the same specified rating 15 amps. Using different
substitutes or fuses with higher ratings, or connecting the unit
directly without a fuse, could cause fire or damage to the stereo

Notes : Ref. No. Part No. Part Name & Description Remarks
1. Be sure to make your orders of replacement parts accord- D201 YESAD167 Diode
D251 YESAD191 Zener Diode
ing to this list.
D270 YESAD192 Diode
2. Important safety notice: Components, identified by D271 YESAD192 Diode
mark have special characteristics important for safety. D272 YESAD192 Diode
When replacing any of these components, use only man- D273 YESAD192 Diode
D274 YESAD192 Diode
ufacturer's specified parts.
D275 YESAD192 Diode
3. Location keys in the remarks column indicates the gen- D276 YESAD192 Diode
eral location of the parts shown in the exploded drawing, D277 YESAD192 Diode
as in a road map. D351 YESAD191 Zener Diode
4. The marking (RTL) indicates that Retention Time is lim- D376 YESAD143 Diode
D401 YESAD144 Diode
ited for this item. After the discontinuation of assembly in
D601 YESAD143 Diode
production, the item will continue to be available for a D672 YESAD188 Zener Diode
specific period of time. The retention period of availability D675 YESAD144 Diode
is dependent on the type of assembly, and in accordance D682 YESAD133 Zener Diode
D683 YESAD133 Zener Diode
with the laws governing part and product retention. After
D701 YESAD193 Diode
the end of this period, the assembly will no longer be D703 YESAD196 Diode
available. D704 YESAD198 Diode
Order intake period is basically six months after the first D751 YESAD197 Diode
shipment. D752 YESAD192 Diode
D771 YESAD195 Diode
5. Reference materials of parts with the TSN mark in the
D772 YESAD192 Diode
remarks column are uploaded in the TSN (Technical Ser- D773 YESAD192 Diode
vice Navigation) system website. Please download from D774 YESAD192 Diode
