carrier, gently press the pins of the chip to conform to the carrier.

CAUTION:

Be sure the NOTCH of the EPROM chip is toward the bottom of the analyzerand all the pins are engaged into the socket. Improper or forcedinstallation will cause irreversible damage to the chip.

5.3.5.6.Align the key of the assembly with the key position of the socket and gently press the EPROM chip and carrier assembly evenly into the PC board socket until fully inserted. A fully inserted assembly will be flush with the socket housing on both sides. A click will be heard when the chip and carrier are firmly in place.

CAUTION:

Do not force the carrier into the socket. If it does not go into the socket, ensure that the key is in the proper location and the IC chip pins are not bent.

If the chip and carrier are not properly installed, a blank blue screen willappear on the front panel display.5.4.Once the EPROM chip is installed, close the analyzer.

5.4.1.Place the replaced chip in the protected packaging for proper disposal according to local regulations.

5.4.2.Reconnect the power to the analyzer.5.5.Turn the analyzer on while depressing the UP arrow.

5.5.1.The analyzer will display message screens. The analyzer will set default constants, dates, and times.

5.5.2.A screen stating SYSTEM INITIALIZATION IS COMPLETE will appear, press any key to return to the MAIN Menu.

5.5.3.After all procedures are complete, pressing any key will return the analyzer to the MAIN Menu.

NOTE:

Following the installation of the new EPROM, the instrument may be ready to recalibrate the syringes, this process will take 3-4 minutes. Allow the process to occur. Additionally, a non-fatal error #38 can be expected.

5.6.Print or record the new memory constants by following Step 5.1.

5.6.1.Verify new constant values. There are new constant values to enter and some variations must be reentered to return the constants to the prior values. Use the Constants Record Form within this procedure as a guide. To enter constant values there is limited access to the FACTORY ACCESS menu.
