Page 8 Using with Network PRECAUTION To use ZEUS Service Manual Ver.2 with network, the file-path names written on the source files of each ZEUS Engine Program Ver.2 and ZEUS Service Manual Ver.2 are to be modified. Perform the procedure described below. Preparation 1.
Page 9 Procedure of File-Path The zeusFPch is the exclusive program to exchange the file-path names written in both source files of ZEUS Manual and ZEUS Engine program into those applicable to the network use. 1. Whenever changing the file-path of both ZEUS Engine Program and ZEUS Service Manual to use with network, pay the attention to set the "Exchange to"...
Page 10 Run the zeusFPch and set "Exchange to" by referring to the examples below. Example 1 : In the "Exchange to" column shows the relation between ZEUS Service Manual and ZEUS Engine Program. ../ counts the relation between. Thus in this case, it must be ../../zeus/ (2 counts). Example 2 : In this case, it must be ../../../zeus/ (3 counts).
Page 11 2. Run the zeusFPch to change the path in the ZEUS Engine Program Ver.2. 3. Set ZEUS Engine Program in the created folder in the server to the "Target Folder", and then press "START". (This procedure is one time only)
Page 12 4. Run the ZeusFPch to change the path in the ZEUS Service Manual Ver2. 5. Set unzipped ZEUS Service Manual in the created folder in the server to the "Target Folder", and then press "START". (This procedure is required whenever placing service manual.)
Page 13 Confirmation Confirm that service manual on the server can be operated normally by client PC. Note: In case of accessing the ZEUS Manual through WEB site, the small pop-up window appears at the left bottom corner on the screen whenever searching the location links. This is not malfunction.
Page 14 Through WEB, ver. 6.5 has been released but with it, the linking function in this manual may not work properly. If ver. 6.5 has been installed, uninstall it and reinstall ver. 6.0. To get ver. 6.0, click the icon, or contact to the nearest Toshiba Service Centre for further assistance. Freezing windows opened (Cannot close the open windows) This may happen occasionally.
Page 15 The real cause has not been found yet but with this condition, nothing disturbs the service manual operation. Continue to use by operating the windows. Precaution when opening the diagrams While opening the diagrams, the menu in the left frame changes its color to GRAY. This is an indication that the viewer is processing.

Page 18 SAFETY INSTRUCTION WARNING: BEFORE SERVICING THIS CHASSIS, READ THE "SAFETY PRECAUTION" AND "PRODUCT SAFETY NOTICE" INSTRUCTIONS BELOW. Safety Precaution WARNING: SERVICING SHOULD NOT BE ATTEMPTED BY ANYONE UNFAMILIAR WITH THE NECESSARY PRECAUTIONS ON THIS RECEIVER. THE FOLLOWING ARE THE NECESSARY PRECAUTIONS TO BE OBSERVED BEFORE SERVICING THIS CHASSIS.
Page 19 6. Always use the replacement parts specified for the particular model when making repairs. The parts used in products require special safety characteristics such as inflammability, voltage resistance, etc. therefore, use only replacement parts that have these same characteristics. Use only the specified parts when the mark is indicated in the circuit diagram or parts list.

SAFETY INSTRUCTION Handling the LCD Module Safety Precaution In the event that the screen is damaged or the liquid crystal (fluid) leaks, do not breathe in or drink this fluid. Also, never touch this fluid. Such actions could cause toxicity or skin irritation. If this fluid should enter the mouth, rinse the mouth thoroughly with water.
Page 23 because any impact can adversely affect the performance. Also use caution when handling the polarized screen because it can easily be damaged. 3. If the panel surface becomes soiled, wipe with cotton or a soft cloth. If this does not remove the soiling, breathe on the surface and then wipe again.
Page 24 6. CMOS-LSI circuitry is used in the LCD module, so avoid damage due to static electricity. When handling the module, use a wrist ground or anchor ground. 7. Do not expose the LCD module to direct sunlight or strong ultraviolet rays for an extended period of time.
Page 25 9. Do not disassemble the LCD module. Such actions could result in improper operation. 10. When transporting the LCD module, do not use packing containing epoxy resin (amine) or silicon resin (alcohol or oxim). The gas generated by these materials can cause loss of polarity.
