Sound leakage from the High- Tone speaker during the use of the headphone set
REF.No. :G - A0 - 085- E0 DATE :24. OCT. 2000
When the volume is increased with the headphone set mounted, sounds may leak from the High -Tone speaker. If the actual occurrence of this problem is reported, please undertake the following countermeasure: Replace the required components mounted on the MAIN C.B. The procedure is as follows: 1) Remove the jumper wire (JW) from the R467, and instead, mount a 27K resistor. 2) Remove the chip jumper wire (JR) from the R468, and instead, mount a 27K resistor. 3) Remove the JR209 27K resister, and instead, connect a chip jumper wire (JR). 4) Remove the JW219 27K resister, and instead, connect a jumper wire (JW). Use either suitable lead wires or conductors as the jumper wires.
Replace R467 JW to 27K Replace R468 JR to 27K Replace JW219 27K to JW Replace JR209 27K to JR|
