Answer 1

Press the FM2 and RDS buttons together (one on top of the other) until 1000 appears on the radio screen. Let go. using the 1-6 buttons on the left, press the 1 button repeadtedly until you get your code's first digit on the screen, the 2 until the second digit, 3 until the 3rd, 4 until the 4th. Press FM2 and RDS together until SAFE comes on the screen. Let go. Radio resets itself.
