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.
Z-BOARD (COMPONENT SIDE)
ECJ1VC1H080C
C2444
2. of 3: If you could not solve the problem by method 1. of 3 then
change components on Z board according to the following table:
