Installation ex factory in units with serial end numbers 061011 to 061085.
Improvements and new functions against 1.336:
1. Self-test as well as continuous self-monitoring expanded. As a result, the potential error messages have become both more detailed and more numerous.
2. Preparation of parallel tables for the monopolar currents Pure Cut, Uro Pure Cut and Argon Cut, for which the maximum output power is now limited to 350 W. However, these tables are not effective yet in HW02 units.
3. Preparation of changeover to a different current logo and a different name – “Air Beam” – for the Macro Spray current. However, this measure is not effective yet in HW02 units.
4. The Macro Spray (AIR Beam) current has been transferred from the first to the second page of the current selection list, thereby exchanging places with the plain Spray current.
This is due to the fact that the plain Spray current is preferred by many users.
5. The Polyp Cut I current symbol has also been provided with a graphical coagulation seam in order to prevent the potential impression that it offered no coagulation at all or less coa-gulation capability than the current used for large polyps.
6. As the option to adjust the output power during HF current activation is not appreciated by all users, this feature can now be disabled for good via the Service menu. As a result, pow-er adjustment is possible only as long as no activation takes place.
7. The maximum output voltage for Micro Coag has been slightly reduced to prevent spark formation.
8. All error messages and alerts are now displayed in red to ensure easy capture by users.
9. The acoustic error signal regime has been harmonized: two deep tones are now emitted in succession.
10. Serious errors are now no longer reversible. Instead, current activation is automatically blocked and the unit must be turned off and restarted before activation is possible again.
Repeated activation attempts are rejected and the error message 164 displayed for infor-mation. Besides, the error code of the serious event that triggered the locking action is dis-played again in such case.
11. The papilla and polyp currents previously tended to be too unstable in their pulse emission performance. Therefore, these and all other currents characterized by a periodic change in their power output have been revised to provide them with a fixed time regime that pre-vents unwelcome output variations, thus preventing loop electrode damage even in ex-treme cases. The effectiveness of the DC regulator has also been improved and the voltag-es have been slightly reduced. To prevent output power fluctuations caused by rapid reope-ration of the footswitch, the regime has been changed so that the output sequence now starts with a coagulation phase and ends with the cutting pulse.
12. Introduction of bipolar auto-start currents. These differ from existing Auto Start/Stop cur-rents in that a fixed switch-off threshold subject to a very high resistance has been imple-mented. This ensures that automatic switch-off takes place only upon releasing the tissue.
However, these Auto Start currents are available only if the hardware ID recognition func-tion correctly identified the bipolar board II in HW02 units, as only this board features the higher-Ohmic impedance monitor required for this function.
13. Voltage limitation (from HW03) supported: The monopolar board III (C40-2281) required for this function is automatically recognized. While the power manager board III (C40-2337) is not a mandatory requirement for running this software, we highly recommend im-plementing it nonetheless.
14. Various currents have been modified regarding maximum voltage limitation. This change requires a C40-2281 monopolar board (HW03 or higher) to be effective. Besides, the mo-nopolar patient circuit controller must be loaded with version 9.00 at a minimum.
15. Polish has been generally implemented as a 7th interactive language, but still has – like Czech – a limitation in that country-specific special characters cannot be displayed.
16. Portuguese is included as well. All characters are correctly displayed in this case.
17. Fine adjustments implemented for Italian and French.
18. Hardware and software configuration now displayed in the Service menu.
19. Instructed specialized personnel can now put the unit into operation for error/fault analysis purposes even if the initial self-test failed. To this end, “backdoor entry” is now possible by pressing the MENU button (repeatedly if more than one error occurs) and entering the ser-vice password into the text editor which is then displayed.
20. This version for the first time has a basic activation log for maximum 36 entries (ring-type memory). Actual output values are not recorded, however, but only represented by fixed values serving as examples. Storage is permanent (non-volatile) in units having a
control-21. The new software version V3.02 of the maxium® Beamer is also included for download in this maxium® software version. However, this presupposes a bootloader in the maxium® Beamer. You can check this situation via the Service menu (version indication). The
changes implemented relative to V3.01 are limited to the expansion of one tolerance range to ensure that series-specific fabrication spread in some Beamer components is tolerated.
Besides, the pressure alarm threshold (e.g. 30 bar) indicated on the maxium® display now fully reflects the true Beamer value. However, it is hardly necessary to update the Beamer specifically with the new software version. Beamer updating is initiated via item “UB” in the Password menu.
22. The ME402 can now display additional activation statistics for the Beamer:
Number of (successful) Beamer activations for Cut Number of (successful) Beamer activations for Coag Number of power-on actions
This information has previously been stored in the error log – which caused irritation in some cases. We therefore decided to transfer this data from the error log to a separate log.
However, deletion of the corresponding entries in the error log should be done only by the manufacturer.
23. The power display of the ME402 has always incorporated a quasi-analog “control bar graph” below the numerical value, indicating the set power relative to the maximum power setting available. It is now possible to choose between this previous indication mode and indication of the actual power output. This setting can be changed permanently and global-ly via the Service menu. Switching the setting to actual power indication will mean that the bar responds only when power is actually emitted (current activated) at the corresponding channel.
24. The LED self-test has been improved to ensure that LED failure is more easily recognized.
25. Software support for the internal real-time clock to make this clock available for servicing purposes. This presupposes a processor board C40-C2217 version 01 or higher (shipped since February 13, 2006). This clock has no functional relevance at all for the unit. There-fore, if it does not work correctly or has meaningless settings, this does not have any ad-verse effects. A corresponding Service menu item for setting the clock has been imple-mented as well, but is offered only if a matching hardware version of the controller board (with functioning buffer battery) is recognized: C40-2217, board version 01 or higher.
26. The buffer battery (3.0 V, Li-cell) – which works only with board versions C40-2217 V01 (delivery started February 13, 2006) or higher – is now monitored. Battery discharge is au-tomatically registered in the Service menu (periodic safety check). The user is not troubled with this in any way.
27. Commonly used bipolar instrument codes are now correctly identified in units with old-type bipolar boards I (C40-1930) as well. An error message is displayed in case of unknown codes.
28. The external Beamer MB181 is no longer supported. Corresponding items have been re-moved from all the menus.
29. KLS Martin logo and support address, as well as the klsmartin.com e-mail address, have been updated.
30. The following boot codes have been implemented to support troubleshooting in case of main controller board failure (indicated by flash signal sequences emitted by the heartbeat LED normally flashing continuously at a rate of 1 Hz):
Heartbeat LED
flash pulses Cause
1 non-assigned
2 External RAM not zero in spite of initialization 3 Bit pattern test failure in external RAM
4 Trap B Interrupt
5 Graphics controller device ID (0x1c) Reg000 not readable!
