3 M Introduction E. Introduction PCB Identification All PCBs are identified by a unique 0 digit internal part number (IPN), e.g , which is screen printed onto the PCB (usually on the top side), as shown in the example below: The last digits of this number define the issue status, which starts at 00 and increments through 0, 0, 03, etc. as the PCB is updated. Some issue PCBs never reach full production status and are therefore not included in this manual. A letter following the 0 digit IPN has no relevance in identifying the PCB for service purposes. Note: It is important that you identify which issue PCB you are working on so that you can refer to the appropriate set of PCB information. Parts Lists The 0 digit numbers ( ) in this Parts List are internal part numbers (IPNs). We can process your spare parts orders more efficiently and accurately if you quote the IPN and provide a brief description of the part. The components listed in this parts list are divided into two main types: those with a circuit reference (e.g. C, D, R, etc.) and those without (miscellaneous and mechanical). Those with a circuit reference are grouped in alphabetical order and then in numerical order within each group. Each component entry comprises three or four columns, as shown below: circuit reference - lists components in alphanumeric order variant column - indicates that this is a variant component which is fitted only to the product type listed description - gives a brief description of the component Internal Part Number - order the component by this number The mechanical and miscellaneous section lists the variant and common parts in IPN order.

4 E. Introduction M Parts List Amendments At the front of the parts list is the Parts List Amendments box (an example of which is shown below). This box contains a list of component changes which took place after the parts list and diagrams in this section were compiled. These changes (e.g. value changes, added/deleted components, etc.) are listed by circuit reference in alphanumeric order and supersede the information given in the parts list or diagrams. Components without circuit references are listed in IPN order. The number in brackets at the end of each entry refers to the Tait internal Change Order document. IPN of new component Change Order number Parts List Amendments R306 Changed from 80Ω to 560Ω ( ) to increase sensitivity (7003). circuit reference or IPN description of change Variant Components A variant component is one that has the same circuit reference but different value or specification in different product types. Where two products share the same PCB, the term variant is also used to describe components unplaced in one product. Variant components have a character prefix, such as &, = or #, before the circuit reference (e.g. &R00). The table below explains the variant prefixes used in T800 Series II products: If the variant prefix is... the component will... & change according to channel spacing = change according to frequency stability # change according to frequency band % change or placed/unplaced for special applications * be unplaced in one product (where two products share the same PCB) 3/03/0 Copyright TEL

5 M Introduction E.3 Grid Reference Index This section contains a component grid reference index to help you find components and labelled pads on the PCB layouts and circuit diagrams. This index lists the components and pads in alphanumeric order, along with the appropriate alphanumeric grid references, as shown below: components listed in alphanumeric order PCB layout reference circuit diagram reference component location on the sheet sheet number component location on the layer layer number - = top side layer = bottom side layer Copyright TEL 30/04/98

Those with a circuit reference are grouped in alphabetical order and then in numerical order within each group. Each component entry comprises three or four columns: the circuit reference, variant (if applicable), IPN and description. A letter in the variant column indicates that this is a variant component which is fitted only to the product type listed. Static sensitive devices are indicated by an (S) at the start of the description column. The mechanical and miscellaneous section lists the variant and common parts in IPN order. The Parts List Amendments box below lists component changes that took place after the parts list and diagrams in this section were compiled. These changes (e.g. value changes, added/deleted components, etc.) are listed by circuit reference in alphanumeric order and supersede the information given in the parts list or diagrams. Components without circuit references are listed in IPN order. Parts List Amendments #C4 Rx High (C): changed from 5P (IPN ) to 8P (IPN ) to allow the VCO to be tuned at the top end of the frequency range (767). Tx Low (B): changed from P (IPN ) to 8P (IPN ) to improve VCO tuning range (7068). #C5 Rx High (C): changed from 8P (IPN ) to P (IPN ) to allow the VCO to be tuned at the top end of the frequency range (767). #C6 Rx low (D): changed from P (IPN ) to 8P (IPN ) to improve loop voltage (70900). Tx High (A): incorrectly listed as P (IPN ) - correct value is 8P (IPN ). Tx High (A): changed from 8P (IPN ) to 5P (IPN ) to improve the loop voltage tuning range at the top of the band (70943/44). C3 Changed 8P 5% (IPN ) to 8P % (IPN ) due to standardisation (780047/48/49/50). Copyright TEL 3/03/0
