+ * This is a simple example to demonstrate how to use DTMF.
  *
  * Connect the HamShield to your Arduino. Screw the antenna 
  * into the HamShield RF jack. 
  * Connect the Arduino to wall power and then to your computer
  * via USB. After uploading this program to your Arduino, open
- * the Serial Monitor. Press the button on the HamShield to 
+ * the Serial Monitor. Press the switch on the HamShield to 
  * begin setup. After setup is complete, type in a DTMF value
  * (0-9, A, B, C, D, *, #) and hit enter. The corresponding
  * DTMF tones will be transmitted. The sketch will also print

  Serial.println(radio.testConnection() ? "HamShield connection successful" : "HamShield connection failed");

  // initialize device
  radio.initialize(); // initializes automatically for UHF 12.5kHz channel

  Serial.println("setting default Radio configuration");


  
  while (digitalRead(SWITCH_PIN));
  
  // now we let the AU ot of reset
  digitalWrite(RESET_PIN, HIGH);
  delay(5); // wait for device to come up
