Cathode ray tubes
Components marked 
on the circuit diagram are critical for safety and include those specified to comply with X-ray emission standards for units using cathode ray tubes and those specified for compliance with various regulations regarding spurious radiation emission.
When servicing units that use cathode ray tubes (CRTs), the cathode ray tubes themselves, the high voltage circuits and related circuits are specifically chosen so that they comply with recognized codes pertaining to X-ray emission.
Consequently, when servicing, replace the cathode ray tubes and other parts with specified parts only. Do not attempt to modify these circuits as any unauthorized modification can increase the high voltage value and cause X-ray emission from the cathode ray tube.
Handle the cathode ray tube only when wearing shatterproof goggles and after discharging the high voltage completely.
Earthing
The rear of a CPU has two separate screw terminals for protective earth 
(PE) and video earth 
(VE).
VE
Metal strap
PE
These are normally connected by a metal strap. The protective earth terminal is internally connected to the protective earth conductor of the power cable. If required, the central earth connection wire of the studio can be connected to terminal PE.
In normal circumstances the connection between the protective earth and the video earth should not be broken.
The metal strap may be removed only if the studio (or OB van) is equipped with separate protective and video earth systems. Under these circumstances the video earth terminal must be connected to the central functional earth potential (video earth) of the studio. This earth potential should have functional protective and noiseless earth (FPE) qualities as stated in the VDE regulation 0800/part2. A low impedance interconnection of both earth conductors must be provided at the central studio earthing point.
WARNING
THE UNIT MUST ALWAYS BE CONNECTED TO
PROTECTIVE EARTH.
Mains Lead Wiring for UK Users
The wires in the mains lead are coloured in accordance with the following code:
GREEN AND YELLOW |
- |
EARTH |
BLUE |
- |
NEUTRAL |
BROWN |
- |
LIVE |
As the colours of the wires in the mains lead of this apparatus may not correspond with the coloured markings identifying the terminals in your plug proceed as follows:
•The wire coloured GREEN AND YELLOW must be connected to the terminal on the plug marked with the letter E or by the safety earth symbol 
or coloured GREEN or GREEN AND YELLOW.
•The wire coloured BROWN must be connected to the terminal marked with the letter L or coloured RED.
•The wire coloured BLUE must be connected to the terminal marked with the letter N or coloured BLACK.

Test Sawtooth |
Lens matching |
A test sawtooth signal is normally only used for adjustmentprocedures.JumperX3onVideoprocessor 1 board provides a choice between two internal signals or an external signal.
Internal signals
Set jumper X3 to position BC to get the nominal sawtooth. This is used for checking amplitudes. Set jumper X3 to position AB to get a small sawtooth (approximately 25% nom.). This small sawtooth is used for checking painting or colour temperature ranges.
External signal
To inject an external test signal first set jumper X3 to position CD (test input). Connect the external test signal to connector X4-1/2. The nominal value of this signal is 700 mV without sync.
The test sawtooth signal is switched on by means of the Operate menu of the camera or the Setup 1 menu of the MCP.
When a camera is supplied with a lens it is not necessary to perform any of the following adjustments asthelensisalreadymatchedtothecamera.However, if you wish to change to a different type of lens or the lens is not supplied with your camera, back focus, white shading and auto iris adjustment procedures may have to be performed.
•Colour balance.
If required, perform the gain adjustment of the preprocessorboardand/orwhiteshadingadjustment procedures, described in section 4.
•Auto Iris Adjustment
If a different lens either works too slow or overshoots too much with the auto iris control, adjust the potentiometer on the lens to obtain acceptable operation. Refer to the lens documentation.
•Back Focus Adjustment
To adjust the back focus of the lens refer to the documentation of the lens.

Private Data
Private data channels can be used for the transmission ofserialdataviathetriaxcable.Forexample,electronic scriptboard or character data for a video display unit can be transmitted to the camera.
The tracker microphone intercom channel is used for the data channel from camera head to base station. The program intercom channel is used for the data channel from base station to camera head. The input and output signals are available on the auxiliary connectors of the camera and base station (for camera see the connectors and cables section). If a channel is used for private data, then of course the original functions are no longer available.
To select the function of the base station to camera channeluseS801ontheAudio/intercomboard.Position AB selects the Progr function (factory setting); position AC selects the private data function.
To select the function of the camera to base station channeluseS802ontheAudio/intercomboard.Position AB selects the tracker microphone function (factory setting); position AC selects the private data function.
Rememberthatthepropagation-delaytimesaredifferent for different triax cable lengths, especially if a return signal is involved. At maximum lengths of 2400 metres the total delay is at least 25 µsec. and can be more than 30 µsec, depending on the type of triax cable.

Introduction |
Printed circuit boards |
The instructions given in this section are restricted to those modules which can be replaced at the first line level. After a printed circuit board has been replaced it is sometimes necessary to carry out adjustments to match the new boards to your camera and so maintain the performance levels. The relevant adjustment procedures are referenced in section 4.
The procedures for removing the modules should be followed in reverse order when remounting the units.
To remove a printed circuit board proceed as follows:
a.Open the side cover (see section 2).
b.Swing the black cover 1 of the printed circuit board open.
c.Pull horizontally on this cover to free the board from its connector and slide it clear of the camera.
