Error Description
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 play.
Radial Error
Triggered when the radial servo is off-track for a certain time during play.
Sledge In Error
The sledge did not reach its inner position (inner-switch is still close) before approximately
6 Sec. have passed by. Inner-switch or sledge motor problem.
Sledge Out Error
The sledge did not come out of its inner position (inner-switch is still open) before approximately
250 mSec. have passed by. Inner-switch or sledge motor problem.
Jump-offtrack error
Triggered in normal play when the jump destination could not be found within a certain time.
When this error occurred, software will try to recover by initiating the jump command again.
If it is recoverable, the disc will continue to play.
Subcode Error
Triggered when a new subcode was missing for a certain time during play.
PLL Error
The Phase Lock Loop could not lock within a certain time.
Turntable Motor Error
Generated when the CD could not reached 75% of speed during startup within a certain time.
Discmotor problem.
Focus Search Error
The focus point has not been found within a certain time.
The carousel switch is not open within certain time. This can happen when either the switch is
defective and closed all the time, or when the carousel is blocked when located exactly at a
disc position.
The carousel position switch did not close within a certain time. This can happen when the
switch is defective and never closes electrically, or when the carousel is blocked in between
two disc positions. The time-out is approximately 5 Sec.
The drawer could not enter the inside position is opening again. This can be caused because
the drawer is blocked by something and cannot go fully inside, or the drawer switch is defective
and does not close.

If sensitivity of frequency counter is too low adjust to max. channel separation
(input signal: stereo left 90% + 9%, adjust output on right channel to minimum)
2)
RC network serves for damping the IF-filter while adjusting the other one.

General
1. Playback Mode
Signal from the playback head DeckA or Deck B is selected and fed through by the Mode Selector IC7710 (HEF4952BT).
The signal is amplified by amplifier IC7720 (AN7323S) before feeding to the IC7740 (HEF4952BT) and out to theAF Board
via connector 1701.
2. Recording Mode
Recording Signal is selected and fed through by the Mode Selector IC7710 (HEF4952BT) which is then amplified by the
amplifierIC7720(AN7323S).TheamplifiedoutputsignalwillpassthroughIC7730(HEF4952BT)forrecordequalizationand
back to IC7710 (HEF4952BT) before registered into the Rec/PB Head of Deck B.
3. Dubbing Mode
In Dubbing mode, signal from the playback head Deck A is selected and fed through by the Mode Selector IC7710
(HEF4952BT) which is then equalised for playback mode by the amplifier IC7720 (AN7323S) so that a flat response is
obtained after the pre-amp. The equalised signal will then follow the same path as in the Recording mode.
4. Mode Selector
The Mode Selector IC7710 (HEF4952BT) caters for 4 inputs signal, namely Playback Signal from DeckA, Playback Signal
from Deck B, Recording Signal and Dubbing Signal.
5. Amplifier PB/REC
Amplifier IC7720 (AN7323S) is for the purpose of amplifying the Playback and Recording signal from the Mode Selector.
6. Automatic Level Control (ALC)
ALCcircuitconsistsofresistors(3760,3765,3766,3767),capacitors(2762,2763)andcontrolbytransistor7787(BC847B).
ALC limits the amplifier output to a constant value when input signal becomes too large, thus limiting recording current to
below saturation level, to prevent recording distortion.
7. Muting Circuit (For Non-Dolby version only)
Switch S4 of the IC7740 (HEF4952BT) is for the purpose of muting the output during Recording mode. During Recording
mode, S4 is closed and shorted to the ground.
8. IC7740 (HEF4952BT)
The function of the IC7740 (HEF4952BT) is to change time constant between 120us Ferro (IEC I) and 70us Chrome (IEC
II)during playbackmode. Itwill automatically determinedwhetherthe tapetypeis 120us Ferro(IECI) or70usChrome (IEC
II). This IC will switch to Flat Gain during the Recording mode.
9. IC7730 (HEF4952BT)
The function of the IC7730 (HEF4952BT) is to change gain and time constant according to tape type and recording speed
toboostrecordingcurrentathigherfrequencyduringrecordingtocompensateforheadloss. Itwillautomaticallydetermined
whether the tape type is 120us Ferro (IEC I ) or 70us Chrome (IEC II).
10. Bias Level
Bias Level making use of the Variable resistor (3773) for adjusting the optimal level of the bias current for Ferro or Chrome.
11. Bias Symm (For Dolby B NR version only)
BiasSymm making use of the Variable resistor (3785) to adjust thebiascurrentforthe left and the right channel tobeequal.
12. PB Switch
PlaybackSwitchwhichconsistsoftheFETs7785(ForDolbyBNRversiononly)&7786(J111)isforthepurposeofproviding
avirtualgroundfortheRec/PBHead(DeckB)duringPlaybackmode. DuringthePlaybackmode,theFETs are turn on and
shorted pin 2 and 4 of connector 1720 to the ground. During Recording mode, the FETs are turn off to allow the oscillator
signal to be superposition onto the Recording signal for recording.
13. Motor Speed (For FR versions only)
During High speed dubbing, a feedback signal from the uP through pin 03 of the IC7610 (HEF4094BT) will trigger the
transistors7622(BC847B)and7616(BC857B)tocauseachangeinthevoltagelevelbetweenHighandLow, thuschanging
the speed of the motor.
14. IC7610 (HEF4094BT)
IC7610 (HEF4094BT) is a Shift Register use for issues the logic for cmos switch ICs (HEF4952BT) via 1A0, 2A1 and 2A2.
It also issues logic to On/Off SOL_A, SOL_B and MOT. Recording speed is controlled via NS/HS.

LOW for NR OFF/ON.
16. 19kHz Filter
The 19kHz filters 5631 & 5632 (LXD-210) in the Dolby circuit is for the purpose of filtering the 19kHz Pilot Tone (for Tuner
signal only) of the Recording signal.
17. Level Adjust

18. Amplifier IC7640 (NJM4560M)
The Amplifiers 7640A & 7640B (NJM4560M) in the Dolby circuit is for the purpose of amplified the Recording signal.
