SUBARU GENUINE
The knobs with numbers larger than 700 on exploded view are not supplied for service parts
because it is difficult to apply grease.
Please change to panel assy when you need repair to the knob.
The CN503 in the ELECTRIC UNIT (X34-485x-xx) is not a replaceable component.
In case of defective of this IC, replace the entire unit (X34-485x-xx).
The IC5, 9, IC21, and IC60 in the DVD unit (X37-1120-03) are not replaceable components.
When these ICs are defective, replace the whole DVD mechanism assembly (X92-5910-01).
You cannot replace only the board.
The IC3, and IC11 in the DVD unit (X37-1100-00) are not replaceable components.
When these ICs are defective, replace the whole DVD mechanism assembly (X92-5500-00).
You cannot replace only the board.

eSatellite SW voltage specification
1) Rated voltage: 5V
2) Rated voltage: See the next table
3) Chattering period of time: 10ms or less
• Take the fluctuation in power supply voltage into account (4.75V~5.25V).
4) Range of output voltage
V2=V1Ra/(Rp+Ra) Ra=R1+(1/((1/R8)+(1/R2+…+R7)))
=R1+R8(R2+…+R7)/(R2+…R8)
• Resistance of SRC: MAX 1.0Ω
• Resistance of BHD harness wire: MAX 0.2Ω
• Take the fluctuation in voltage into account (4.75V~5.25V).
• Calculate the range taking the tolerance in resister (±2%) into account to allow the margin in voltage determination
