2-2 Right Side Section (Cont'd)

# Tape transport direction indicators

REV FWD

One of the indicators lights according to the

 

tape transport direction.

 

is displayed in the record-pause

 

mode and in the still picture mode.

$ Remaining Battery Power Display

The 7-dot segment bar display shows the remaining battery

power.

 

* To display the remaining battery power accurately, set

the VCR Setup Menu item No. 396 BATTERY TYPE

according to the type of the battery pack in use.

See "Remaining Battery Power Display" on page 24.

& Warning indicators

 [AUTO OFF] indicator

Lights when a non-recoverable error (e.g. tape winding

error, drum stopped, etc.) occurs with the unit. This

indicator also lights if condensation occurs.

See "TROUBLES WITH ERROR CODE OUTPUTS"

on page 100.

 [DEW] indicator

Lights when condensation (dewing) occurs on the drum

or other mechanism in the unit.

The unit rejects all operations while this indicator is lit.

When the condensation has disappeared, the indicator

turns off and the unit accepts operations again.

% Counter display

• Usually, this section shows the data of the CTL counter,

time code or user's bit. The display mode can be selected

with the 4 COUNTER switch.

• Displays the VCR setup menu data when the GY-DV550

is in the VCR setup menu mode by pressing the MENU

button ! on page 15. The VCR setup menu includes the

hour meter (accumulated drum operating time).

• This section shows an error code when an abnormal

condition occurs with the unit.

See "Counter Display Contents" on page 24.

See "TROUBLES WITH ERROR CODE OUTPUTS"

on page 100.

^ Section for time code related indications

[SLAVE] Slave lock indicator

This is the slave lock indicator which lights when the built- in time code generator is slave-locked (synchronized) with the LTC time code signal input at the TC IN connector.

For the slave lock of the time code, see page 64.

[PB] Time code playback indicator

Lights when the time code is in playback mode.

[NDF] Non-drop frame indicator (U MODEL)

Lights when the internal time code generator or the playback time code framing mode is non-drop frame. “DF” is displayed in the drop-frame mode.

• It never lights when the CTL counter is displayed.

[HOLD] indicator

Lights when the time code generator display is held by pressing the HOLD button in the time code setting block. The time code or user's bit can be preset while this indicator is lit.

See “Displaying Time Code” on page 62.

 [SERVO] indicator

Lights in the case of trouble with the drum servo during

recording to indicate that normal recording is not being

accomplished.

 [RF] indicator

Lights when the video head is clogged. Head clogging is

detected during playback and recording check using the

RET button on the lens section. Note that it is not detected

during recording.

* Should this indicator light up, clean the head using the

provided head cleaning tape. For instructions on head

cleaning tape, read “Precautions for Use of Head

Cleaning Tape” on page 8.

 [Li] Lithium indicator

Lights and indicates the necessity of replacement when

the lithium battery that backs up data of the built-in time

code generator is nearly exhausted. See "Inserting and

Replacing Backup Lithium Batteries" on page 36.

r t y

1 Cassette cover Pressing the EJECT switch on top of the section opens this cover so that a videocassette can be inserted or removed from the unit. The cover can be locked automatically by pushing and closing it.

If the cassette cover is not closed, the GY-DV550 will remain inoperative.

 

Memo:

 

To prevent penetration of foreign objects into the unit,

 

do not leave the unit with the cassette cover open.

2

[MONITOR OUT] monitor output connector (BNC)

 

Connector for composite video signal output.

 

The following video signals are outputted.

E-E video or playback video of VCR

Screen mixed with characters.

External video signal (When VTR INPUT switch is set to AUX) Select whether to output the E-E video/playback video of VCR or character-mixed screen by CHARACTER MIX of the Camera Setup screen. See page 83

Memo:

Select whether to output signals that include setup in the E-E video in SETUP of the Camera Setup screen. See page 83

*Setup is not included during E-E of IEEE1394. (U MODEL)

VITC time code is not outputted from this connector.

3

[Y/C OUT] connector (4P)

 

Separate YC video signal output connector.

4

[TC IN] connector (BNC)

 

Input connector for the SMPTE-standard LTC signal. The built-in

 

time code generator can be slave-locked with the input time codes.

 

If the user’s bits should also be slave-locked, set the VCR Setup

 

Menu item No. 403 U-BIT SLAVE to “TC&UB”.

 

*

When the TC GENE switch (& on page 15) is set to REC or

 

 

REGEN, or the VCR Setup Menu item No. 398 SSF MODE is set

 

 

to “CUE MODE” or “MARK MODE”, slave-locking will not take place.

 

 

For the slave lock of time code, see page 64.

5TC OUT connector (BNC)

 

Output connector for the LTC signal from the built-in time

 

code generator.

 

The time code recorded on the tape is not output in play mode.

6

[LINE OUT CH-1/CH-2] connector (RCA)

 

Output connector for audio signals.

 

Outputs the input audio signal in the record and stop

 

modes.

 

Outputs the playback audio signal in the playback mode.

 

Alarm sound is not output.

7

[VIDEO OUT] Video output connector (BNC)

 

Connector for composite video signal output.

 

Camera images are constantly outputted as through images.

 

Camera images are outputted even during external video sig-

 

nal input (when VTR INPUT switch 9 on page 15 is set to

 

AUX).

Whether to output signals with setup can be selected in SETUP of the Camera Setup screen. See page 83 (U MODEL)

8

[GENLOCK/AUX IN] Generationlock/Aux signal in-

 

put connector

 

Synchronous signals (black burst signals) are inputted when

 

the GY-DV550’s camera image is synchronized with an ex-

 

ternal component. Composite video signals are inputted

 

when recording video signals from an external device with

 

this unit. Which video signals to input can be selected us-

 

ing the VTR INPUT switch on page 15.

 

Memo:

Video signals from this connector are not outputted to the VTR/RM multi-pin connector 8 on page 21.

When the camera remote control unit is connected

with setting the MODE switch 6 on page 20 to RM, this connector will be used for synchronous signal input regardless of the VTR INPUT switch setting.

The camera cannot be synchronized with a VCR playback signal.

When the power is switched ON while an external sync signal is input, the screen moves in a vertical direction for a few seconds. this is not a malfunction.

If the external sync signal is disrupted during recording, the “SYnc inh” (SYNC INHIBIT) indicator is displayed on the counter display and recording stops.

If the external sync signal is disrupted during playback, playback of the disturbed video image continues. Start playback again after synchronization is obtained and the signal is stabilized.

The screen will distort when inputting sync signals to both the main unit and camera remote control unit.

This external video signal input (AUX IN) connector is an auxiliary connector. The bandwidth of Y signals will be 6.75 MHz (8 bit) regardless of the inputted signal bandwidth.

9

[REMOTE] connector

 

A part of the unit's functions can be controlled externally.

 

For connecting the local remote control unit (RM-LP55/RM-

 

LP-57), nonlinear editing device, etc.

 

When connecting the local remote control unit, Set VTR

 

 

Setup menu No. 050 REMOTE SELECT to LOCAL or

 

IEEE1394.

 

When connecting a nonlinear editing device, set to

 

 

IEEE1394+RS232C.

 

 

For details, please consult your JVC dealer.

Note: If you make an error in the setting, disconnect the connector cable before performing setting again.

0 Microphone attachment holes For attaching the microphone holder KA-A50 (optional).

See "Attaching the Microphone (optional)" on page 34.
