I'd recommend trying to repair the remote with the box. Be sure to have direct line of sight between the remote and the box. Also make sure both the box and TV are powered on:
-Press and hold the Setup button until the Power button light blinks twice.
-Press the Cox Menu button on the remote control.
-Use the Up or Down arrows to highlight Customer Support, then press Select.
Result: The Customer Support menu displays.
-Use the Up or Down arrows to highlight Technical Support, then press Select.
-Use the Up or Down arrows to highlight Remote Control Pairing, then press Select.
Result: A message will be displayed with instructions on how to pair the remote control.
To program the remote complete the following steps.
a.Press and hold Setup until the remote light blinks twice.
b.Press the Cox Menu button and the RF pairing code will be displayed on the TV.
c.Using the remote keypad, enter the three-digit code displayed on the TV.
d.The remote light will blink twice to confirm the code has been successfully entered.
I am so very sorry for the frustration. Upon holding the Setup button, does the Power light flash 2x? If so when you attempt entering the code 982, are you able to see a the menu screen after pressing the menu button? The remote controls are very sensitive, so you may have to try a few times.
Exchanging the remote is an option. I'd like to try sending a refresh to your mini box first. Please send me an email to firstname.lastname@example.org with your service address. Be sure to include the status of the light on your box. Is the light flashing or steady? I look forward to your response.
