13.3. (VHS) SELF-DIAGNOSIS FUNCTIONSThis model has a self-diagnosis. If the VHS section detects trouble during installation or during use, the power is automaticallyturned off or become power-save mode and it is memorized into the EEPROM (IC9705) as error code of two-digit number. It smemorized error code can be displayed in "second" display portion (the last 2 digits of the FIP) by placing the unit is Service ModeNumber 2 when turning on the Service Information Display as for example "01" or "02" etc. as below. If a second error occurs, themost recent error will be memorized and can be displayed in Service Mode Number 2. It can be memorized until 3 self-diagnosishistories in maximum.In order to erase the memorized error code, press FF and EJECT buttons on the Front Panel simultaneously over 5 seconds duringturning on Service Information Display mode.13.3.1. MEMORY OF THE SELF-DIAGNOSIS HISTORY*This is effective only in Service Mode 3, 4, 5.13.3.1.1. ERROR NUMBERS AT A GLANCEMemory No. (Error Code) Reason01 The cylinder could not be started. (Error of the cylinder or the cylinder driver.)02 The CAP FG could not be detected.03 Mechanism lock during without the unloading and the cassette-up.04 Mechanism lock during unloading05 S-reel pulse cannot be detected during unloading. (Error of the S-reel circuit or the Capstan circuit)06 Mechanism lock during the Cassette-up.15 S-reel pulse cannot be detected when a cassette tape is inserted.(Error of the S-reel circuit or the Capstan circuit)16 Detection of the Cylinder lock during the constant rotation17 Detection of S-reel lock during the constant tape running18 Detection of T-reel lock during the constant tape running2*Refer to following tableAn error while the PG Automatic Adjustment80 An exceptional ejection depends on a accidental errorNote:2* is as follows.20 NG1 in the PG Shifter Automatic Adjustment (The cylinder rotation is unstable during the automatic adjustment.)21 NG2 in the PG Shifter Automatic Adjustment (The vertical sync signal is lacked while over 5 seconds on the alignment tape.)22 NG3 in the PG Shifter Automatic Adjustment (The installing position of Heads to the cylinder is our of specification.23 NG4 in the PG Shifter Automatic Adjustment (The servo is not locked to the cylinder for more than 10 sec.)13.3.1.2. MEMORY FOR THE SELF-DIAGNOSIS HISTORY3. The self-diagnosis result is memorized the state of the moment of detecting.4. There are the histories from number 1 to number 3.5. The latest error is memorized on history number 1, and then the old histories are shifted to the history number 2 and 3.The error code memorized in the history number 2 and 3 is over-written by shift.4. If the latest error is the same with the history number 1 (2nd-latest), it is not memorized.(The same error code is not memorized in succession)13.3.1.3. CLEAR FOR THE SELF-DIAGNOSIS HISTORY1. Press FF and EJECT buttons on the VCR simultaneously over 5 seconds during turning on Service Information Display mode.13.3.1.4. INDICATION OF THE SELF-DIAGNOSIS HISTORYThe self-diagnosis histories can be indicated on the FIP with Service Mode number 3 to 5.The procedure of service mode setting and indication format are the same as usual.28DMR-ES30VEG / DMR-ES30VEC / DMR-ES30VEB
