8 There should be no semi-broken wires, scratches, melting, etc. on the coating of the power cord.
Damaged power cords may lead to fire accidents, so please be sure that there are no damages.
If you find a damaged power cord, please exchange it with a suitable one.
9 There should be no spark traces or similar marks on the power plug.
When spark traces or similar marks are found on the power supply plug, please check the connection and advise on secure
connections and suitable usage. Please exchange the power cord if necessary.
a Safe environment should be secured during servicing.

1. SERVICE PRECAUTIONS
1.1 SERVICE PRECAUTIONS
1. You should conform to the regulations governing
the product (safety, radio and noise, and other
regulations), and should keep the safety during
servicing by following the safety instructions
described in this manual.
2. Before disassembling the unit, be sure to turn off
the power. Unplugging and plugging the connectors
during power-on mode may damage the ICs inside
the unit.
3. To protect the pickup unit from electrostatic discharge
during servicing, take an appropriate treatment
(shorting-solder) by referring to "the DISASSEMBLY".
4. After replacing the pickup unit, be sure to check the
grating.
5. Be careful in handling ICs. Some ICs such as MOS
type are so fragile that they can be damaged by
electrostatic induction.
6. Sheet (Mechanism cover), CNM9404 can not be reused
if you remove it.

1.2 NOTES ON SOLDERING
For environmental protection, lead-free solder is used on the printed circuit boards mounted in this unit.
Be sure to use lead-free solder and a soldering iron that can meet specifications for use with lead-free solders for repairs
accompanied by reworking of soldering.
Compared with conventional eutectic solders, lead-free solders have higher melting points, by approximately 40 C.
Therefore, for lead-free soldering, the tip temperature of a soldering iron must be set to around 373 C in general, although
the temperature depends on the heat capacity of the PC board on which reworking is required and the weight of the tip of
the soldering iron.
Compared with eutectic solders, lead-free solders have higher bond strengths but slower wetting times and higher melting
temperatures (hard to melt/easy to harden).
The following lead-free solders are available as service parts:
Parts numbers of lead-free solder:
GYP1006 1.0 in dia.
GYP1007 0.6 in dia.
GYP1008 0.3 in dia.

5.2 ERROR CODE LIST
- CD Error Messages
A
If a CD is not operative or stopped during operation due to an error, the error mode is turned on and cause(s) of
the error is indicated with a corresponding number. 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
Depending on display capability of LCD used, display will vary as shown below. xx contains the error number.

6. SERVICE MODE
6.1 CD TEST MODE
During pressing the "SOURCE" and "RPT" keys simultaneously, perform the reset-start, then turn ON
the CD to enter the CDS test mode.
• How to issue the 1 - 6 keys in the 08 model's slave test:
The specification of the 08 model does not include the 1 - 6 keys issuance function for H/U and the remote control unit.
Therefore, in order to issue commands in a slave test, use the direct FUNCTION keys alternatively to enable the equal
key command sending function to the existing models.
Outline) Use the direct FUNCTION keys to display, select, or issue the KEY 1 - 6.
<Direct FUNCTION keys and corresponding functions>
Direct FUNCTION key Normal mode Slave test mode
A Selecting a key command
B
C Switching a screen
S.Rtrv
RDM Issuing a key command

• For convenience, a name of each direct FUNCTION key is shown as "A", "B", and "C".
• How to issue the 1 - 6 keys for the CDS source:
(The areas below are overwritten and displayed on character strings for the normal mode display.)
1 During the slave test mode, the key name "K1" is shown at the left by default.
In this condition, press the A key to toggle K1 - K6, and select a command to be sent to the slave.
