The documented June 2006 specimen falls outside the production period covered by the APC SurgeArrest Recall (2013). Despite its later production date, the external enclosure remains visually similar to earlier recalled examples.

	The documented example also exhibits substantial enclosure yellowing and a clearly preserved "shadow" where an adhesive label previously protected a portion of the plastic from environmental exposure. This condition provides useful evidence regarding the mechanisms responsible for long-term discoloration of consumer electronic enclosures.

	The documented example was manufactured in the Philippines, consistent with the archive's documented 2008 and 2017 APC PRO7 specimens. Earlier documented examples manufactured in 1998, 1999, and 2002 were produced in China, suggesting that APC relocated PRO7 production between 2002 and 2006 while retaining a largely unchanged external design.

	The documented June 2006 specimen introduces a previously undocumented cord supplier within the APC PRO7 product family. Unlike the archive's documented 2002 specimen, which utilized a Hi-Pro cord assembly, and the 2008 specimen, which utilized a Baohing-manufactured cord, the 2006 example employs a Chung Kwang-manufactured 14 AWG SJT cord carrying UL file number E54024 and CSA file number LL65965.

	The specimen demonstrates APC's continued use of the ©2002 suppression-board generation at least four years after its introduction ~~and approximately eleven~~ years ~~before the adoption~~ of the later ©2009 board ~~revision~~ documented in the archive's 2017 example.		The specimen demonstrates APC's continued use of the ©2002 suppression-board generation at least four years after its introduction. Together with the archive's documented September 2008 example, the June 2006 specimen provides additional evidence that APC retained the ©2002 board design through multiple years of production prior to the later ©2009 board generation documented in 2017.

			The documented example was manufactured in the Philippines, consistent with the archive's documented 2008 and 2017 APC PRO7 specimens. Earlier documented examples manufactured in 1998, 1999, and 2002 were produced in China, suggesting that APC relocated PRO7 production between 2002 and 2006 while retaining a largely unchanged external design.

			The documented June 2006 specimen also introduces a previously undocumented cord supplier within the APC PRO7 product family. Unlike the archive's documented 2002 specimen, which utilized a Hi-Pro-manufactured cord assembly, and the 2008 specimen, which utilized a Baohing-manufactured cord assembly, the 2006 example employs a Chung Kwang-manufactured SJT 14/3 cord carrying UL file number E54024 and CSA file number LL65965.

			The documented example additionally exhibits substantially greater enclosure discoloration than the archive's documented 2002 specimen while remaining visually similar to the heavily yellowed 2008 example. The preserved label shadow provides one of the clearest examples of differential enclosure discoloration currently documented within the APC PRO7 product family.

Following removal of the enclosure screws, the housing separated into upper and lower sections containing the outlet-contact assemblies, brass power-distribution bus bars, switch and circuit-breaker assembly, surge-suppression circuitry, and attached power cord.

The lower housing contains the outlet-contact assemblies, brass bus bars, power-cord termination, rocker-switch assembly, resettable circuit breaker, and surge-suppression circuit board. The overall internal architecture closely resembles the archive's documented September 2008 APC PRO7 specimen and differs substantially from the earlier 1998 and 1999 examples, suggesting that APC retained this design throughout much of the mid-2000s production period.

	Inspection identified a surge-suppression circuit board carrying a ©2002 copyright marking, demonstrating continued use of APC's ©2002 board generation at least four years after its introduction. The finding further supports the conclusion that APC retained this suppression-board design through multiple years of production.

	The documented example utilizes a Chung Kwang-manufactured SJT 14/3 power cord carrying UL file number E54024 and CSA file number LL65965. The cord represents a previously undocumented cord supplier within the APC PRO7 family currently preserved by the archive.

The documented example therefore utilizes APC's ©2002 suppression-board generation, the same board family documented in the archive's December 2002 and September 2008 APC PRO7 specimens. The finding demonstrates that APC retained this board design for at least several years of production.

	The suppression circuitry incorporates multiple metal-oxide varistors (MOVs), EMI/RFI filtering components, status-indicator circuitry, and APC's established surge-protection architecture used throughout the documented ©2002 generation.

Heavy copper traces and substantial soldered interconnections are used throughout the suppression board.

			The specimen demonstrates APC's continued use of the ©2002 suppression-board generation at least four years after its introduction and approximately three years before the adoption of the later ©2009 board revision documented in the 2017 example.

			== Date Codes ==

	~~== Date Codes ==~~		Multiple independent indicators support a June 2006 manufacturing date for the documented APC PRO7 specimen.

			The serial number, 4Z0638P12907, identifies the unit as a 2006 production example. Independent confirmation is provided by molded date-code wheels located within the upper enclosure.

			The year wheel indicates 2006 while the adjacent month wheel indicates June, corresponding exactly with the manufacturing date derived from the serial number.

			The documented example was manufactured in the Philippines, as indicated by the serial-number label located on the underside of the enclosure.

	~~Discussion of~~ serial ~~numbers, molded~~ date wheels~~, labels, component date codes, manufacturing~~ evidence~~, and production chronology~~.		The agreement between the serial number and the internal date-code wheels provides strong evidence supporting June 2006 manufacture.
