RUNNING MODE
This running mode is a mode by which the recording is compulsorily deleted with ALL-ERASE after
U-TOC is written when the recording of MD ends, and the recording is repeated again.
This TEST MODE is continue recording (loop recording), it is for recording stop when MD end.
This TEST MODE is only can use manual operation recording [MD REC PAUSE]. CD synchro recording
(CD MD REC,BEST HIT REC,1CD
1.Setting the TEST MODE
1:Setting normal speed recording mode by pressing together [POWER key], [2 key] and [STOP key]
of Remote controller.
2:If normal speed mode is default then change to high speed mode, press [HIGH SPEED CD>MD key] of
main body before recording start.
3:Once change to high speed mode, TEST MODE is continue until release.
4:Return to normal speed recording mode, it should release the TEST MODE then resetting the
TEST MODE.
(REMARKS) Case of CD high speed recording : After setting TEST MODE, if it need setting
CD play mode or repeat mode. Press [HIGH SPEED CD > MD key] setting high speed
mode. RUNNING MODE is start by REC STANDBY (indicate [RUNNING MODE] on LCD)
at [MD REC PAUSE key] then playback the CD.
(During recording, LCD indicate [RUNNING MODE])
2.Release the TEST MODE
Test mode is release by POWER OFF.
Indication the [CAUTION !] when abnormal
1.Detect the abnormal condition of stability power supply
Abnormal detection dine of the stability power supply(REG.) at CPU [SAFETY1~3] port (IC801:6,7,9pin),
when system CPU (IC801) supply voltage (US D5.6V) is normal condition.
Watching the abnormal at POWER ON condition, if detect the abnormal indicate [CAUTION!] and come
under stability power supply (8V/10V or 12V OR 6V), and indicate [DATA(HEX)] of the abnormal port
voltage then power off to forcibly.
Detect the abnormal condition of stability power supply is next.
[8V/10V] : SAFETY1 port (Power supply of full color LED/Power supply of CD mechanism)
[12V] : SAFETY2 port (Power supply for tuner module REG, MD mechanism REG, volume IC,
[6V] : SAFETY3 port (Power supply for MD mechanism, power supply for OPT. module, power
(REMARKS) Safety port voltage at detect the abnormal condition.

2.Abnormal detection of CD mechanism
When detect the abnormal condition of CD mechanism, indicate [CAUTION ! ] and come under
condition and back light is change to [RED] forcibly.
Indication when mechanism abnormal condition.
[CD INITIAL] : Abnormal condition when mechanism initialize after power cord to connect to
[CD MECH] : Abnormal condition when mechanism initialize at return operation, it is
