To: All harman/kardon Service Centers
Models: AVR7000
Subject: Switched AC Accessory Outlet Dead
The Switched AC Accessory Outlets on the AVR7000 are used to power up any low-wattage
device when the AVR7000 is switched on with the System Power Control. Ordinarily this means
CD players, DVD players, Tape Decks, etc. or any device not exceeding 100 watts per outlet.
These accessory outlets are not intended to be used with higher-power devices such as television
sets, power amplifiers or powered subwoofers.
However, under some circumstances, even the use of a recommended device connected to the
AVR7000's Switched AC Accessory Outlets may briefly exceed the current rating of the internal
1A AC accessory fuse, and blow the fuse.
In the event you receive an AVR7000 with the complaint "The switched AC accessory outlet
at the rear of my receiver is dead", perform the following procedure:
1) Remove the top cover, (16 Black Phillips screws).
2) Locate F451, a 1A GMC (5 x 20mm) fuse at the rear corner of the unit, where the AC power
cord enters the rear cover. Remove it and replace with a 3.15A GMC (5 x 20mm)
Slo-Blo fuse, h/k part# 5508302735 . Original fuse can be extracted with a pair of long-nosed
pliers.
3) Replace the top cover.
4) Test the Switched AC Accessory Outlets by connecting a low power device, such as a CD
player, DVD player, or Tape Deck and assure the unit powers up normally when the AVR7000
System Power Control is switched on.
