  Subject:                  The whistling noise from right speaker.

  Symptom:                  The whistling noise from right speaker.

  Background:               The audible noise occurred by the difference of the oscillation frequency between each amplifier circuit
                            on Z board.

  Remedy:                   Change the oscillation frequency of IC2305/IC2306/IC2307/IC2308 on Z board by one of the following
                            method.

  Method:                   1. of 3: Please add a capacitor (ECJ1VC1H080C) onto the capacitor of C2444.
