There are two ways of solving the communication issue when the EC1 message appears.
1. Preform a "Clear Config Memory" in the boot loader
2. Do a cold boot of the Transport Pro
Take out the batteries in the Transport Pro, and only run on mains
Turn off the Transport Pro
Press and hold the white button (the one beside the On/Off button)
Press On/Off button and keep holding the white button pressed when the Transport Pro powers up
When it's up running release the button, and verify that the "EC1" message is gone
Turn the Transport Pro off and reinstall batteries and turn the monitor on again.
In both cases preform test's as the "EC1" message is a indicator that preventive maintenance is required. Also check that all the settings are right.
The clear config memory will erase all the settings back to factory default
