Serial/Model Number Configuration
MEGA-TEC wall-mount units configure some settings
based on the model number that is input into the unit.
The model and serial number are entered at the factory,
and should be retained during a software update.
However, after a software update, it is best practice to
verify that the model number and serial number are
still present and accurate. If the model number and/or
serial number is missing or incorrect, they will need to
be re-entered.
To update serial/model numbers:
1. Press MENU key to go to the Main Menu screen.
2. Press UP or DOWN keys and ENTER key to enter
ENGINEER password 9254.
3. Press UP or DOWN keys to scroll to Adv. Sys.
