HOW TO TAKE OUT THE CASSETTE TAPE IN CASE OF EMERGENCY

An emergency system on this unit enables the cassette tape to be taken out manually. When a cassette tape is stuck, take it out as described below. Procedure 1. Gear Å : Emergency gear for MODE MOTOR 2. Gear i : Emergency gear for REEL MOTOR 3. Gear Ç : Emergency gear for HOUSING MOTOR (1) In order to turn the mode motor, turn the gear Å (red color) in the direction of the arrow. While turning the gear also push it in to drive loading / unloading.

Gear Å

Fig. 1.7.3 (3) Repeat steps (1) and (2) alternately and little by little until the tape is wound completely into the cassette. (4) Confirm that the tape is completely wound. Then, turn the gear Ç (red color) in the direction of the arrow to eject the cassette housing. Take the cassette out when it comes out of the loading slot.
Gear Ç

Fig. 1.7.1 (2) To wind the tape, when the tape is loosened a little, put a screw driver in the emergency gear i, which drives the reel. (The drive direction does not matter.)

1.8.7 ERROR HISTORY menu It can display 4 errors that have occurred in the past. Initially, when there is no error history in the memory, the first error to occur will be logged in the first position (HISTORY-1). The second and third errors to occur will be logged in (HISTORY-2) and (HISTORY-3). All subsequent errors will be overwritten in (HISTORY-4). The fourth and subsequent errors are set to overwrite in order to prevent the user from repeatedly attempting to use a malfunctioning unit and thereby erasing any record of the initial cause error. Be sure to clear the error history before returning a repaired unit to the customer. When resetting ERROR HISTORY, set the parameter for "CLEAR" to "EXECUTE", and press the [SET] button.

1.8.10 EEP-ROMS (1) EEP-ROMS and stored data AG-DV2500 is equipped with two EEP-ROMS for the purpose of data stored, and their contents are as per the following list. When the circuit board or EEP-ROM is replaced, there will be no data in the EEP-ROM. When the unit is powered up, and the SYSCON CPU or MSD CPU recognizes that there is no data in the EEP-ROM, it automatically writes initial data into the EEP-ROM to initialize it. The memory data shown in Table 1.8.10 will all be reset back to default settings, so it will be necessary to perform necess ary adjustments and settings again.

(2) IEEE1394 ID setting method IEEE1394 equipped units have an ID, as defined by the IEEE1394 standard, stored in the internal EEP-ROM (IC 301). At the time of production, the ID assigned for each individual unit are written into the EEP-ROM, and a sticker bearing the ID is affixed inside the unit. When the EEP-ROM (DV/CPU board assembly) or DV/CPU board assembly is replaced, the ID needs to be set again. Procedure for setting IEEE1394 ID The ID is an 8 digit, hexadecimal code, with 1 high Byte being the model code, and 3 low Bytes being individual to the unit. The model code is automatically initialized, so only the lower 3 Bytes of individual code need to be set manually. Go from Service Menu OTHERS Menu MEM. EDIT (Memory Edit) to select the address in the ID data section and make the setting directly. The 3 low Byte address is as follows. Make the setting while confirming the ID printed on the label (ID: 80xxxxxx) pasted on the inside of the AG-DV2500 (See Fig. 1.8.10). IEEE1394 ID data : 80 Address data xx xx xx (Indicates on the label of AG-DV2500 inside.)

Setting procedure (1) Press the 8 or 9 button to move the cursor to MEM. EDIT. (2) Press the : button to make the ADR parameter blink. (3) Press the 8 or 9 button to select ADR parameter "391". (4) Press the : button to make the DATA parameter blink. (5) Press the 8 or 9 button to set ADR = "391" for the ID. (6) Press the [SET] button to confirm the DATA parameter. (7) In the same manner, select ADR parameter "392" and "393" to set the ID data.

1.8.11 Real-time clock The IC2002 (RS5C314) on the MAIN circuit board is a CMOS real-time clock IC that sends time/calendar data to the CPU via serial transmission. When power is not being supplied to the BT2001, there is a secondary battery (3V) to backup the IC2002. By charging for 4 hours, it provides 3 months of backup. When power is being supplied, AL3V is sent through D2002 to the IC2002 8pin, and through D2003 the BT2001 enters a state of being charged. When external power supply (AL3V) ceases, BT2001 is discharged through D2002 and the current is sent to the IC2002 8pin, resulting in a state of backup.
