This arrangement is intended at reducing nonsense calls from the users and also for facilitating trouble analysis and repair work in servicing. (1) Basic Indication Method 1) When SERRORM is selected for the CSMOD (CD mode area for the system), error codes are written to DMIN (minutes display area) and DSEC (seconds display area). The same data is written to DMIN and DSEC. DTNO remains in blank as before. B 2) Head unit display examples Depending on display capability of LCD used, display will vary as shown below. xx contains the error number. 8-digit display ERROR–xx 6-digit display ERR–xx 4-digit display E–xx (2) Error Code List Displayed error code Description of the code and potential cause(s) Code Class Electricity Carriage Home NG CRG can't be moved to inner diameter. 10 CRG can't be moved from inner diameter. SERVO LSI ComC → Failure on home switch or CRG move mechanism. munication Error 11 Electricity Focus Servo NG Communication error between microcomputer and SERVO LSI. Focusing not available. → Stains on rear side of disc or excessive vibrations on REWRITABLE. 12 Electricity Spindle Lock NG Subcode NG Spindle not locked. Sub-code is strange (not readable). → Failure on spindle, stains or damages on disc, or excessive vibrations. A disc not containing CD-R data is found. D Turned over disc are found, though rarely. CD signal error. AGC protection doesn't work. Focus can be easily lost. → Damages or stains on disc, or excessive vibrations on REWRITABLE. 17 Electricity Setup NG 30 Electricity Search Time Out Failed to reach target address. → CRG tracking error or damages on disc. 44 Electricity ALL Skip 50 Mechanism CD On Mech Error Skip setting for all track. (CD-R/RW) Mechanical error during CD ON. → Defective loading motor, mechanical lock and mechanical sensor. A0 System Power Supply NG Power (VD) is ground faulted. → Failure on SW transistor or power supply (failure on connector). E Remarks: Mechanical errors are not displayed (because a CD is turned off in these errors). Unreadable TOC does not constitute an error. An intended operation continues in this case. Upper digits of an error code are subdivided as shown below: 1x: Setup relevant errors, 3x: Search relevant errors, Ax: Other errors. F 42 DEH-P4500R/XM/EW 1 2 3 4 5 6 8 7 7.

Do not squeeze top frame's front portion too tight, because it is fragile. A B Do not squeeze. - Removing the Upper and Lower Frames C 1. With a disc clamped, remove the four springs (A), the two springs (B), the two springs (C), and the four screws. 2. To remove the upper frame, open it on the fulcrum A. 3. While lifting the carriage mechanism, remove the three dampers. 4. With the frames removed, insert the connectors coming from the main unit and eject the disc. Caution: Before installing the carriage mechanism in the frames, be sure to apply some alcohol to the dampers and set the mechanism to the clamp mode. Upper Frame A A C A A Carriage Mechanism B Damper Lower Frame Damper B D - Removing the Pickup Unit E 1. Set the mechanism to the clamp mode. 2. Remove the lead wires from the inner holder. 3. Remove the two washers, styling holder, change arm, and pickup lock arm. 4. While releasing from the hook of the inner holder, lift the end of the feed screw. Caution: In assembling, move the planet gear to the load/eject position before setting the feed screw in the inner holder.
