Passo 1 Headphone Jack  ¶ 

  • Remove the two Phillips #00 screws securing the on/off switch to the front bezel.

  • When replacing, check the protrusion of the switch. There is a small plastic spacer adhered to the inside of button which may come off with cleaning. Without a spacer, the button may not protrude enough to be depressed. If lost, it can be replaced with a suitable thickness of stiff plastic (eg shirt box lid).

Passo 4  ¶ 

  • Remove the four Phillips #00 screws securing the volume and mute switch.

  • The volume switch assembly sits on top of the mute switch. Make sure that the small soft pad on the mute switch is not lost, otherwise the mute switch will sit very loosely after reassembly.

  • The mute switch assembly screws should be tightened with the switch in the off position. Check the protrusion of the switch when turned on, since it may not stick out far enough to operate if the switch assembly is incorrectly positioned. (Check the gap between the switch frame and the bezel (white gap showing between the two screws near the 6). The screw on the far right is slightly longer than the other 3 screws. When reassembling the phone, keep this in mind.
