[Page 1] ESAOTE S.p.A. MyLabTwice MyLabClass Family SERVICE MANUAL

[Page 2] Introduction This manual describes for the Service technicians the MyLabTwice and MyLabClass Family system functions and the block diagram of the boards that implements these functions. The service manual is available in English only. The manual is addressed to all the Service centres directly authorised by ESAOTE. All the operations described in this manual are not critical from a safety point of view. Do not attempt to service MyLabTwice and MyLabClass Family units unless this service manual has been consulted and understood. Enter and context menu keys are respectively indicated as ENTER and UNDO keys in this manual. The LCDs display are not considered to be a field serviceable item, therefore the manual doesn’t include its block and electric diagrams. ii

A CAUTION describes the precautions which are necessary to protect the equipment. Be sure that you understand and observe each of the cautions and warnings. iii

[Page 4] Chapter 1 - Service Characteristics The aim of this introductory chapter is to illustrate some MyLabTwice and MyLabClass Family fundamental characteristics to the technical staff, in particular, where to find the equipment status and how to keep it up to date. Identifying the Boards MyLabTwice and MyLabClass Family design is based on the use of modular, functionally isolated printed circuit boards (PCBs) and subassemblies known as Field Replaceable Unit. This modularization greatly simplifies on-site service and repair. In most cases, on-site maintenance is accomplished by removing and replacing the PCBs or subassemblies. Most boards of MyLabTwice and MyLabClass Family are identified: • by its Reference (950..) and its description, which is always indicated on the labels bar. • by the Serial Number (SN), indicated on the labels bar. Board Board Serial Reference Number • by the Configuration Index (CI), indicated by two decimal figures on the labels bar. The Configuration Index represents the HW level of the board. The Configuration Index is loaded in specific components mounted on each board. In the boards not equipped with flap this information is on labels affixed on the printed circuit.

[Page 6] Chapter 2 - Equipment In this chapter are listed the tools you need in order to access MyLabTwice and MyLabClass Family internal parts, to activate the Service procedures and to perform a functional test of the unit. Disassembling Equipment In order to access MyLabTwice and MyLabClass Family , the following tools are needed: The disassembling procedures are detailed in Section 2 Dynamometric Phillips electric screwdriver Large, medium and small tips Short Philips screwdriver Small tip Slotted screwdriver Large and small tips Box wrench Allen screwdriver Socket Wrench Tweezer Point pliers Small tip The use of an electric screwdriver allows the access time to be minimized. Low torqueses are recommended. Service Procedures Service key The service procedures that require an interaction with the unit, as for example the P/N 8610264000 language setting, can be activated only through the service key. The service key is one USB key which allows the Technician to start the unit in service modality. It’s necessary to connect the key to one of the USB plugs, located to the right of the touch-screen, with the unit off and then turning the system on. S E C T I O N 1 3 3 3 3

[Page 7] Figure 1 (USB Service key) Figure 2 (key inserted) With the USB service key connected the system starts with Windows XP and it’s possible to enter in the various menu of the unit, add/remove programs/SW/files. Without this HW key it’s not possible to access to the system’s error files (it’s only possible to download them by main menu). If the procedure is not carried out properly, the system doesn’t allow the access to the menu and, in some cases, the following message is shown: The symbol shown on the left is used in this manual to indicate all the procedures that require the use of the key. USB Medium and Re-writable CD To perform a complete check of the unit, it is suggested to always have an USB medium and a re-writable CD. These tools allow the service technician to test the functioning of the DVD burner and of the USB ports. Upgrading Disks It is suggested to always have the last revision of the unit upgrading and Recovery Disk together with the pertaining upgrading instructions. These tools allow the service technician to install again the software on the unit, should it be necessary. S E C T I O N 1 4 4 4 4

[Page 10] Chapter 3 - Precautions A series of precautions that must be observed each time you perform an operation on MyLabTwice and MyLabClass Family are emphasised below: • the equipment must always be switched off and disconnected by the main power supply before carrying out any service operation. In the same way, all the probes and peripherals (external monitor, printer, video-recorder...) must also be disconnected and placed in a safe place. • the boards must be removed when the equipment is powered off. • an electrostatic discharge occurring through the contact with the operator, can irreparably damage the electronic components on MyLabTwice and MyLabClass Family boards, that are sensitive to electro-static discharges: we therefore recommend that you take precautions to prevent these discharges each time a board has to be removed/installed. In operational terms, this means: o The machine must rest on an electro-static mat connected to earth. o The service technician must also be connected to the same earth each time he removes or installs the boards. o The boards and components must always be moved in their special electro-static containers. o For the service on the field, use the specific kits including the anti-static mat. The chapter entitled “ MyLabTwice and MyLabClass Family Parts List” details the sub-assemblies that are to be considered sensitive to electro-static discharges (ESD). When the board is ESD sensitive, you can find on the PCB master this symbol. REFERENCE: IEC 61340-5-1 (2007) 7 7 7 7 S E C T I O N 1
