Enable/Disable Functions will be the first screen to appear.
NOTE
MX20 power must be cycled before configuration changes will take affect.
After a configuration change, a message will appear on the screen telling you to wait 30
seconds before turning off power. You may continue to make configuration changes without
pausing; however, do not turn off power to the MX20 until waiting 30 seconds after the last
configuration/ setting change. The message will disappear when it is safe to cycle power.
