In Brief: On this site you will find pictures and technical information about Service Modes, Circuit Diagrams, Firmware Update procedure, Disassemble procedure, Universal remote control set-up codes, Troubleshooting and more....

If you go into the profession, you will obtain or have access to a variety of tech tips databases HERE IT IS Master Electronics Repair !.

These are an excellent investment where the saying: 'time-is-money' rules. However, to learn, you need to develop a general troubleshooting approach - a logical, methodical, method of narrowing down the problem. A tech tip database might suggest: 'Replace C536' for a particular symptom. This is good advice for a specific problem on one model. However, what you really want to understand is why C536 was the cause and how to pinpoint the culprit in general even if you don't have a service manual or schematic and your tech tip database doesn't have an entry for your sick TV or VCR.

While schematics are nice, you won't always have them or be able to justify the purchase for a one-of repair. Therefore, in many cases, some reverse engineering will be necessary. The time will be well spent since even if you don't see another instance of the same model in your entire lifetime, you will have learned something in the process that can be applied to other equipment problems.
As always, when you get stuck, checking out a tech-tips database may quickly identify your problem and solution.In that case, you can greatly simplify your troubleshooting or at least confirm a diagnosis before ordering parts.

Happy repairing!
Today, the West is headed for the abyss. For the ultimate fate of our disposable society is for that society itself to be disposed of. And this will happen sooner, rather than later.

TERUMO TE331 - TE332 -Terufusion Syringe Pump - E2PROM INITIALIZE and AGING

TERUMO TE-331 – TE332 Terufusion Syringe Pump. How to initialize E2PROM.
Medical (Electronic) Equipment.
E2PROM INITIALIZING
RAM data is erased and E2PROM is refreshed by ROM data [default data at factory].  This operation resets all the settings to the default.  Readjust required.
  1. Set the internal DIP switches 1 and 2 to ON and OFF respectively.
  2. While holding down the [STOP] switch, press the On/Off switch.  The display first shows “888.8”, then “FACt”, and a short beep follows.  Release the switches and check the display has changed to “”dIAg”; which stands for Diagnosis.  Note:  If you press the On/Off switch without pressing the Stop switch “Er91” appears on the 7 segment display.  Turn off the pump, and repeat the procedure above.  If you do not release the switches at the beep, the display changes to ‘Er 8”.  Once ‘Er 8’ appears, you have to turn off the pump, and repeat the procedure above.
  3. When “dIAg” is displayed, press the Display Select switch  3 times.  Check the display shows “CLEA” which stands for clear.
  4. Press ‘Stop ‘switch, and the display shows “E or J”.  E is for Europe, and J is for Japan.
  5. Press and hold 'PURGE’ switch about 1.5 seconds to choose ‘E for Europe’.
  6. Initialization of E2PROM starts.  The display changes to ‘Eur’.  As the initialization proceeds, first “0       “, then “00     “,and “000 “, lastly “0000” appears on the display.the switch for Japan is the Start.  If the Start switch is pressed, “JP” appears on the display.
  7. When successfully completed, can hear a short beep and see the display of “good”.
  8. In case of failure, “bAd” is displayed.  Then the display returns to “CLEA”.
  9. Press On/Off switch to Exit the initializing E2PROM mode.
