• 3). Press and hold the button for that type of device on the remote, then press and hold the "OK" button.
  
  
• 4). Release the buttons and wait for the device key to blink twice.
  
  
• 5). Type in the four-digit code using the number pad. The device key blinks three times to indicate the code is accepted. If it turns on steadily for several seconds, the remote didn't accept the code and you must start over.
  
  
• 6). Point the remote at the device and press the "POWER" button on the remote. If the device turns off, the code is correct. If not, try another code. If none of the codes for your device manufacturer work, proceed to Section 2.
