SERVICE BULLETIN
Date Issued: 10/17/2010
Bulletin Part Number: 309505-B4
Product: SoundDock
®
10 Digital Music System.
Subject: The black plastic insulator that is adhered to the underside of the power supply shield is missing and
through hole component leads may be too close to the conductive shield.
Disposition: All systems built prior to 8/25/2010 (DOM 0238) could potentially be missing the insulator.
DOM range = All system built prior to DOM 0298
Symptom: System may fail HiPot testing. Component leads may arc to the power supply shield.
Reason: The black plastic insulator prevents the primary component leads from arcing to the secondary side of
the power supply.
Solution: Inspect the SoundDock 10 by looking under the bottom plate (system does not need to be disas-
sembled) and confirm the black plastic insulator is in place. If missing, install new insulator and shield with part
numbers shown below.
