arrows and remove the panel. Remove the screws of each speaker
unit and then remove the speaker units.
Type.2
Remove the grill frame and four pieces of rubber caps by pulling
out with a flat-bladed screwdriver. Remove the screws from hole
where installed rubber caps. Insert a flat-bladed screwdriver into
the position indicated by the arrows and remove the panel. Remove the screws of each speaker unit and then remove the speaker
units.
Type.4
TOOLS
1 Plastic head hammer
2 (() flat head screwdriver
3 Cut chisel
12 3
How to Remove the PANEL, FR
1. Insert the (() flat head screwdriver tip into the gap
between the PANEL, FR and the PANEL, SPKR. Tap the
head of the (() flat head screwdriver with the plastic
hammer head, and create the clearance as shown in Fig-1.
2. Insert the cut chisel in the clearance, and tap the head of
the cut chisel with plastic hammer as shown in Fig-2, to
remove the PANEL, FR.
Type.3
Insert a flat-bladed screwdriver into the position indicated by the
arrows and remove the panel. Turn the speaker unit to counterclockwise direction while inserting a flat-bladed screwdriver into
one of the hollows around speaker unit, and then remove the speaker
unit. After replacing the speaker unit, install it turning to clockwise
direction until "click" sound comes out.
