1.Position the red label side of the lower acoustic tube on the upper side, insert while aligning the connection ridge of the tube main unit with the connection groove of the fixing base, and secure while pushing downwards (the slide distance is approximately 10mm). Fully secure by inserting to the bottom of the tube fixer.

When cutting one acoustic tube and using it on the upper and lower sides of the acoustic I/O tube, install packing between the acoustic I/O tube and the upper acoustic tube.

2.Remove the temporary installation jig from the main unit of the acoustic I/O tube. While storing the microphone cord that protrudes from the lower side of the main unit into the cord space of the fixing base, insert by aligning the connection ridge of the main unit with the connection groove of the fixing base, and while pushing the tube connector into the lower acoustic tube, push downwards and secure (the slide distance is approximately 10mm).

3.Position the blue label side of the upper acoustic tube on the lower side, insert while aligning the connection ridge of the main unit and the connection groove of the fixing base, and while pushing into the acoustic I/O tube connector, push downwards and fix (the slide distance is approximately 10 mm). The top should be near to the position inside the driver unit shown by the tube top position diagram.

Do not damage the rubber seal of the driver main unit.

4.Further loosen the set screw that is lightly fixed to the driver main unit so that the driver main unit can slide. While pulling down the driver main unit, insert the rubber seal into the hole on the main unit of the acoustic tube, being careful not to damage it. When the rubber seal is fully inserted, further pull down the driver main unit until the rubber seal produces a hermetically sealed effect, and at this point fully tighten the set screw of the driver main unit. Fix the removed driver unit cover.

•When pulling down the driver main unit so that the end of the rubber seal makes contact with the tube main unit, it helps if the rubber seal is moved a little to make it easier to access the hole in the tube main unit.

After installation, take measures to prevent it from falling.

6.Splice the cables.

•Speaker cable: Splice the input cable that comes from the driver main unit with the transmit output speaker cable that comes from the main unit on the operator side, which was previously pulled through the cable hole in the ceiling.

•Microphone cable: Splice the microphone input cable that comes out from the top of the acoustic I/O tube with the receive microphone input cable that comes from the main unit on the operator side,which

was previously pulled through the cable hole in the ceiling.

1. Use a splicing method where the cables can be insulated. Insulation crimping is recommended.

2. When putting the cover on and completing the work,the cables are stored inside the box, so cut the cables to the minimum required length.

3. Be sure to splice the cables with the correct polarity.
