POSSIBLE CAUSE
VOLUME is not adjusted
REMEDY
Adjust the VOLUME
Headphone is connected
Mains cable is not securely connected
Disconnect headphone
Connect the mains cable properly
Batteries are flat Replace batteries
Batteries are incorrectly inserted
Insert the batteries correctly
Changing over from mains to battery
supply without removing the plug
Electrostatic discharge
Weak radio aerial signal
Interference caused by the vicinity of
electrical equipment like TVs, video
recorders, computers, engines, etc.
The CD is badly scratched or dirty
Pull out the mains plug from the
unit's AC MAINS inlet
Disconnect the set from power supply
reconnect it after a few seconds
Aim the aerial for optimum reception:
— FM/SW: incline and rotate telescopic
antenna
— AM/MW/|W: rotate the entire set
Keep the radio away from electrical
equipment
Replace or clean the CD, see maintenance
No CD is inserted
The CD is inserted upside down
Insert a CD

The laser lens is steamed up
The CD is damaged or dirty
Wait until the lens has cleared
Replace or clean the CD

1) In sets with 30kHz grid on FM band it may occur that the
tuned frequency is indicated wrong on the display because
of tolerances of the discriminator filter.
For that reason the testsoftware is prepared for an
automatic IF-offset correction.
Note: This test functions only with the East European
tuner version /14/34,
The test was executed on every set in the production line.
In case the discriminator filter has to be exchanged
the automatic IF-offset correction should also be
executed after repair.
To execute the automatic IF-offset correction:
* feed a strong 87.5MHz signal to the antenna
* press the PROGRAM button
The uP starts now several times the search mode.
If the transmitter was found at 87.5MHz the stop-frequency sent by the
radio IC is compared with the nominal frequency. When the same
difference is found twice the value will be stored as offset.

Focus Error
Triggered when the focus could not be found within a certain time when starting up
the CD or when the focus is lost for a certain time during playing the CD.
Subcode Error
No subcode could have been read, even not after retrying 10 times to restart the PLL
and jumping 10 tracks. When this happens the servo is stopped and restarted (as if
the user would have pressed STOP and then PLAY immediately) to recover.
Out of lead-in during reading TOC
Triggered when during reading the TOC the lead-in (track no. 0) is left.
This can be caused by a misaligned inner-switch or by a disc with a mispositioned lead-in.

Turntable motor error
Generated when the CD did not reach 75% of speed during startup within a certain time.
Discmotor problem.
Too less offtracks. Triggered when the servo processor counts too less tracks in a defined
time during JUMPS. This can be caused by a disturbed HF-signal (the tracks cannot be
recognized exactly) or slide motor problems.
E 1020 PLL lock error
When the PLL did not lock after 10 retries then this warning message is generated and
the servo is stopped and restarted (as if the user would have pressed STOP and then
