IdentificationandStatus

To indicate the status of a drawing, a box with the

numbers 0 to 9 is shown in the bottom-right of the

drawing. The number that is crossed-out is the status

numberof the drawing. Forexample, in theillustration

below, the status is 1.

A sticker is used on the units themselves to identify

them and to indicate their status. For example, in the

illustration below, the top line is the 12-digit number

that identifies the unit type.

The first four digits of the number on the second line

representadatecode(year, week); the next fourdigits

represent the serial number for that week.

Thenumberin the grey areaindicates the status ofthe

unit. The last two digits represent the number that will

be given to the next status. However, if these two

digits are contained in a box, then this is the current

status. For example, in the illustration above, the

current status of the unit is 01.

Line 1 392240700000

Line 2 123456AA0101

Line 3 VR/0123456789

Line 1

This is the code number of the printed circuit board

assy. (PCB)

Line 2

This is the serial number of the PCB. The first 6 digits

andthe2letters are for internal use.Thelastfour digits

reperesent the date of the manufacturing: wwyy.

Example:

123456AA1402 means the PCB is manufactured in

week 14 of the year 2002.

Line 3

This is the status of the PCB.

The digit after the first slash is the status. If there is no

number before the slash, it means that the status is

less than 10, a 1 before the slash means the status

is between 10 and 19, a 2 before the slash means

between 20 and 29 etc.

Example:

- VR4567891012 means status 4

- VR3/78901234 means status 37.

Example of LDK number:

LDK 4501/01 means 8926 450 10101

LDK 4500/00 means 8926 450 00001

Numbers of printed circuit board assy

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

complywithrecognized codes pertaining toX-rayemission.

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.

Handlethe cathoderaytube onlywhenwearing 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).

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.
