A. ON/OFF Volume Control Knob:

go through a power-up self-test.
If the power-up test is successful, a splash screen will appear on the radio
display followed by the Home screen returning to last channel and zone
selected when radio was on. The radio will return to the last channel that it
was set to when it was powered off, no matter what position the channel
selector knob is on. If the radio power-up test is unsuccessful an Error
message will appear. Turn the radio off, check the battery, and turn the radio
back on. If the radio still does not pass its self-test, it is defective. Follow
procedure in Addendum 4 for placing radio OOS.
