Console Memory (RAM)
When you record show information, the information is saved in the
console's RAM (Random Access Memory). All information remains in
memory when the console is turned off because the RAM has a battery to
keep the memory active. At some point however, the battery will fail. When
the battery fails, console memory can be lost! For this reason, it's important
to frequently back up all show and configuration data frequently.
Most people choose to backup their console at the completion of every
rehearsal or major set of changes. This usually is a sufficient frequency
of backups, however, you should backup as frequently as you need to
ensure that if the console lost your memory, your show would not be in
jeopardy.
To change the internal battery, see
