6.1 ASL SECTION ADJUSTMENT
Note:
A
1) Only if ASL parts (shaded ones below) get changed, you need adjustments for ASL.
2) When you disconnect the connector for ASL, you need to be careful.
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.

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

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.

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.)
