Memory Access Time<br />
After the amplifier receives the commands listed below, a period of time is needed for processing the<br />
EEPROM access. After issuing these commands, do not interrupt the power or issue commands during<br />
the specified processing time, since an EEPROM error or data loss can result.<br />
