  2. What is postponement ? • Postponing the branding and naming of the instrument after final assembly. • Loading model specific software as late in the manufacturing process as possible. • Using same hardware for many product families.

  3. Why postponement ? • Saving manufacturing costs • Lowering inventory SKU’s • Ease inventory handling • Benefit from CCS (Common Custom Solutions)

  6. Model Series Level (MSL) - bullet points • Branding hardware (Hybrids) • All AUDIOmaster TPI’s checks MSL • Always go to same or a lower MSL level • Never go to a higher MSL level. • Generic faceplates starts on the highest MSL level (25).

  7. MSL – how it works • Model series level is a way to ensure that instruments are not upgraded in software levels. • AUDIOmaster Test Programs will allow for instruments to go to a lower Model Series Level. • Same functionality is known in earlier product families: • A Canta4 product cannot be converted (upgraded) to a Canta7 product. • A Canta7 product can be converted to a Canta4.

  8. Model Series Level check • Every test program have a MSL • Test program read MSL from device • Compare with MSL in test program • If test program MSL is equal or lower than device MSL then proceed otherwise halt.

  9. Postponed FDI load - flow chart Determine Gain/Output requirements. (High Power or Normal power) Select CCS faceplate assembly in appropriate Form Factor and Power settings from stock. Run the selected test program as normally. (TPI will automatically upload the correct FDI into the instrument) AUDIOmaster will perform necessary HI-calibrations according to selection of test mode and instruments model. (Input-, Output-, IAD calibration) AUDIOmaster will test instrument and generate a test report with the correct FDI loaded. AUDIOmaster will set the appropriate MSL (Model Series Level) according to selected TPI Determine form- factor and model from order. (CIC - CIC-B – ITC - ITC-D - ITE etc. ) Read order form Determine test mode and select options. [ Final / Repair / Fp ] (TC / VC / PB etc.) Complete final assembly of instrument according to order form. (add options etc.) Determine appropriate AUDIOmaster Test Program (.TPI)

  10. MSL procedure • All AUDIOmaster TPI’s has a MSL: • Current MSL levels are: • ReSound Metrix = 12 • ReSound Pixel = 8 • ReSound Plus5 = 5 • CCS Generic faceplate assemblies all loaded with MSL = 25 6 different situations are shown in next slides Select AUDIOmaster TPI and start test. TPI reads MSL of the Device Under Test (DUT) TPI compares MSL of DUT with own MSL Continue test and FDI load Abort test and FDI load MSLDUT >= MSLTPI ? Y N

  11. MSL procedure – exmp. 1 (normal new production) Select AUDIOmaster TPI and start test. TPI reads MSL of the Device Under Test (DUT) TPI compares MSL of DUT with own MSL Example: Plus5 ITC-D selected (MSL = 5) Abort test and FDI load 25 Bigger or equal to 5 ? CCS (generic) faceplate under test (MSL = 25) • Result: YES • Continue test and FDI load • Load Plus5 image into instrument • CCS instrument is now a Plus5 • New MSL in device = 5 MSLDUT >= MSLTPI ? Y Continue test and FDI load N MSLDUT = 25 MSLTPI = 5

  12. MSL procedure – exmp. 2 (attempt on upgrading) Select AUDIOmaster TPI and start test. TPI reads MSL of the Device Under Test (DUT) TPI compares MSL of DUT with own MSL Example: Metrix MX70 selected (MSL = 12) Abort test and FDI load 5 Bigger or equal to 12 ? Plus5 RP70-D BTE after repair. (MSL = 5) MSLDUT >= MSLTPI ? Y Continue test and FDI load N MSLDUT = 5 MSLTPI = 12 • Result: NO • Abort test and FDI load • “Upgrading” not allowed • Give warning to operator • MSL in device still 5

  13. MSL procedure – exmp. 3 (mistake on TPI select) Select AUDIOmaster TPI and start test. TPI reads MSL of the Device Under Test (DUT) TPI compares MSL of DUT with own MSL Abort test and FDI load • Result: YES • Continue test and FDI load • Loads a Plus5 RP50-D image in RP30 • Test fails – mismatch between specs and instrument hardware. • New MSL in device still 5 • Can be corrected with new test with correct TPI 5 Bigger or equal to 5 ? Plus5 ITC RP30 after repair (MSL = 5) MSLDUT >= MSLTPI ? Y Continue test and FDI load N MSLDUT = 5 MSLTPI = 5 Plus5 RP50-DP selected (by mistake) (MSL = 5)

  14. MSL procedure – exmp. 4 (critical mistake on TPI select) Select AUDIOmaster TPI and start test. TPI reads MSL of the Device Under Test (DUT) TPI compares MSL of DUT with own MSL Abort test and FDI load • Result: YES • Continue test and FDI load • Loads RP50-DP image in MX50-DP • NB! Test PASS but mismatch between Model and algorithm packages. • New MSL in device is now 5 • Cannot be corrected with new test 12 Bigger or equal to 5 ? Metrix ITC MX50-DP after repair (MSL = 12) MSLDUT >= MSLTPI ? Y Continue test and FDI load N MSLDUT = 12 MSLTPI = 5 Plus5 RP50-DP selected (by mistake) (MSL = 5)

  15. MSL procedure – exmp. 5 (Brand switch - future use) Select AUDIOmaster TPI and start test. TPI reads MSL of the Device Under Test (DUT) TPI compares MSL of DUT with own MSL Abort test and FDI load • Result: YES • Continue test and FDI load • Loads Beltone One image in Metrix • ReSound Metrix is now Beltone One • New MSL in device is now 10 12 Bigger or equal to 10 ? Metrix ITC HP faceplate (re-plated) (MSL = 12) MSLDUT >= MSLTPI ? Y Continue test and FDI load N MSLDUT = 12 MSLTPI = 10 BELTONE One ITC HP (MSL = 10)

  16. MSL procedure – exmp. 6 (Brand switch - future use) Select AUDIOmaster TPI and start test. TPI reads MSL of the Device Under Test (DUT) TPI compares MSL of DUT with own MSL Abort test and FDI load • Result: YES • Continue test and FDI load • Loads ReSound Pixel image into Beltone One • Beltone One is now ReSound Pixel • New MSL in device is now 8 10 Bigger or equal to 8 ? Beltone One ITC-D HP (MSL = 10) MSLDUT >= MSLTPI ? Y Continue test and FDI load N MSLDUT = 10 MSLTPI = 9 Pixel PL30-DP (MSL = 8)
