If this happens, execute the following procedure to reset the microcomputer and return the unit to its normal operating condition.Please note that resetting the microcomputer will clear the contents of the memory and returns the unit to the state it was in when it left the factory.Unplug the power cord from the wall outlet, then plug it back in while holding down the POWER key.With the power cord plugged in, turn the POWER key OFF. Then, while holding down the ON/STANDBY key, press POWER.FM indoor antenna (1)(T90-0836-05)AM loop antenna (1)(T90-0852-05)Remote control unit (1)RC-R0609/R0610*AC plug adaptor (1) (E03-0115-05)* Use to adapt the plug on the power cord to the shape of the wall outlet.
