For turtech technical support contact Starlite consumer electronics (USA) INC 303 W, Artesia Blvd Compton CA 90220 Phone 1-866-387-2027 They can help you with all of your Questions about Trutech I found it MY operation manual but I did not find the codes it may be in another book that came with My turtech. I also sent an email to Cox cable to see if they could get the codes. when they email me back if they give the codes to me I will post them. I also just called Starlite consumer electronics and all you get is a voice message telling which number to press for what you would like to know. when do pick the number for your question then you get a recording telling you to leave your message and they will call you back in about 24 hours If they call me back with the codes I will post them. I hope that this Helps. Pastor Hal
