To replace the PROM, complete the following steps: Remove all power (AC and battery) before proceeding with PROM replacement. If necessary, disconnect any installed option modules which may inhibit access to PROM. Locate U14 in the center right of the MS-5210UD(E) board (refer to the illustration on the following Replace the PROM in U14 using a static-free PLCC IC extraction tool as follows: Insert hooks of IC extraction tool into the slots of the IC socket (refer to illustration below). Gently squeeze the handles of the removal tool and pull to lift the existing firmware IC from socket. Save the removed firmware IC in the event the replacement IC is damaged during installation. Line up the replacement IC so that its polarization corner (flattened) is aligned with the corner of the socket. Insert the replacement IC by gently pushing it into the The IC should be flush with the socket. Reconnect any option modules which were removed in Step 2. Reconnect power (AC and battery).
