We recommend that biomedical maintenance preform this procedure, if possible.

The sensors in the i-STAT cartridges are standardized against plasma methods used by major laboratory systems. The i-STAT is programed with CLEW software, the coefficients of which are determined by this standardization process. Due to possible changes in the manufacturing process, the CLEW software requires recalibration to avoid drift from major laboratory systems. This is why software updates are mandated to occur twice a year.

Step 1: Be certain both i-STAT devices have at least 7.5 volts of battery power remaining.

Step 2: Turn the power off on the receiving device. The power on the receiving device will remain off for the entire procedure.

Step 3: Place both devices on a flat surface with the infrared windows aligned approximately 1 foot apart.

Step 4: Turn on the sending device, press Menu, and select option 7 for Utility.

Step 5: Press ENT when prompted for a password.

Step 6: In the utility menu press 1 for Send Software.

Step 7: Press 1 for JAMS###/A##.

Note: the numbers have been replaced with # in this example; they will change with each software update.

Step 8: When the sending device displays Waiting to Send, start sliding the receiving device towards the sending device with the infrared windows aligned until the sending device displays Sending. Do not lift it off the flat surface.

Step 9: Wait until the sending device returns to the utility menu and displays Last send successful before moving devices.

Step 10: Run the external electronic simulator on the receiving device to verify successful software update.
