Refer to the sentence and the figure below. When you disconnect the ord ssy (6990) that connects between SP P and Microphone P, get your hand on the connector. Never pull the cable directly because it's very week and easy to be cut. Hook your pointed fingers' nail, and you can disconnect it easily

40 Preset conditions 1. Set VR401 around the center of the adjustable range. Input Output djustment (MI) (Pin 74 : test point "SL1") dj.point Spec. y using the jig(n-906,n-912), Observe the output at VR ±30mV apply a sine wave of 100dSPL LS1 on a audio analyzer voltage directly to the MI terminal. (orresponding to analog (lose up as much as possible.) meter 7Hz). To connect the mp unit and the SP unit, use Jig GG1153 and GG1245. aution: 1) efore starting measurement, be sure to perform the initial check for the SL adjustment jig. (The sound pressure level should be 100dSPL at the sound emission section.) 2) Note that it may take 20 seconds or more to obtain waveforms, in some cases. o not switch off the jig soon after starting measurement. onditions: 1) This adjustment is sensitive to external shocks or wind. uring adjustment, keep away the product and jig from them. udio analyzer SP UNIT Side SP UNIT Side SL1 VR401 Side MP UNIT MIROPHON UNIT Side N906 N905 MI MI401 N901 N902 MR- N902 SP L+ R+ N-MU (TX+) TX+ (TX+) TMUT TML+ (SP) L- R- SG MUT (TX-) TX- (TX-) (MUT) ML- 13.2V MR+ N901 + WL+ WR+ RL+ RR+ L+ R+ +2 WL- WR- GN RL- RR- L- R- 13.2V 13.2V 0V 13.2V + - Regulated Power Supply
