Do Not Delete the Left and Right hard Buttons! Remember, your
RC9200/5200 is programmed at the factory with the Browse
feature. If you accidentally reprogram the Left/Right hard buttons
from the home panel, you cannot restore them with the remote
control. The only way to restore deleted back and ahead global
buttons is to use a Windows PC with RCEdit.
