Refer to the sentence and the figure below. When you disconnect the Cord Assy (CDE6990) that connects between DSP PCB and Microphone PCB, get your hand on the connector. Never pull the cable directly because it's very week and easy to be cut. B C Hook your pointed fingers' nail, and you can disconnect it easily.

(Corresponding to analog (Close up as much as possible.) meter 7Hz). To connect the Amp unit and the DSP unit, use Jig GGD1153 and GGD1245. Adjustment Adj.point Spec. VR401 314±30mV Caution: 1) Before starting measurement, be sure to perform the initial check for the ASL adjustment jig. (The sound pressure level should be 100dBSPL at the sound emission section.) 2) Note that it may take 20 seconds or more to obtain waveforms, in some cases. Do not switch off the jig soon after starting measurement. Conditions: 1) This adjustment is sensitive to external shocks or wind. During adjustment, keep away the product and jig from them.

GENERAL INFORMATION 7.1 DIAGNOSIS 7.1.1 DISASSEMBLY A - Removing the Case (Fig.1) 1 Case Remove the two screws and then remove the Case. - Notes the Cover (Fig.1) Never remove the Cover unless you need to do so because it is firmly adhered to the chassis with double-faced tape. Also, do not reuse the removed Cover and double-faced tape becuase they may probably be damaged. 1 1 B Cover - Removing the Shield Case (Fig.2) 1 Fig.1 Cover Seal 1 Remove the two screws. 1 2 2 C Remove the two screws and then remove the Shield Case with the Cord Assy, Seal and Cover on it. Notes) When you install the Cover, put the Cord Assy fully inside the Cover. (Make the length of the visible part of heat-shrink tube of the Cord Assy to be 1 mm or shorter when the Cover is seen from above the top.) 2 Cord Assy - Removing the DSP Unit (Fig.3) 1 D Shield Case Fig.2 DSP Unit Remove the solder and then straight the tabs at three locations indicated. 1 1 E 1 Remove the DSP Unit 1 1 Fig.3 41 GM-8027ZT/WL 5 6 F 7 8 1 A 2 3 4 - Removing the Shield Case (Fig.4) 1 1 Remove the five screws and then remove the Shield Case. 1 1 B 1 1 Shield Case - Removing the Amp Unit (Fig.5) C 4 Fig.4 4 4 Amp Unit 3 1 Remove the six screws. 2 Remove the two screws and then remove the Heat Sink. 3 Notes) Remove the Heat Sink without removing the Cover in Fig.1. 3 Remove the two screws. 4 Remove the three screws and then remove the Amp Unit.
