APPENDIX E: FIRMWARE UPGRADES_______________________
When connecting to a P4800 for the first time, you may be prompted to upgrade its firmware. If prompted, an
upgrade is required before you can use the new features and enhancements of the P4800 System Processor
version 4.0 software.
Before proceeding with the upgrade, you must disconnect all Shure Link cables and any external control
devices. You should also close all other open applications. Connect directly to the P4800 using an RS-232
cable.
You may then make a backup copy of all data in your P4800 by clicking on the [Backup Device] button and
following the instructions. When the backup is complete, the firmware upgrade will begin. Do not interrupt the
upgrade once it has begun!
Note: If the firmware upgrade fails for any reason (such as a power failure or a disconnected cable), you must
select [Firmware Upgrade] from the [File] menu to relaunch the upgrade process.
