I have a 2006 ADDCO DH1000 message board trailer that I recently purchased. The trailer is in excellent condition all around with the exception that when I turn the power on and the current message operates properly, I am unable to get the keypad to respond with anything other than "PLEASE WAIT..." Therefore, I can't program any other messages to display on the board. I've called ADDCO a number of times and left messages requesting to purchase an operator's manual, but they have yet to return my calls. Internet searches turn up little to no information on these machines, and there's no one in my neck of the woods that repairs this equipment. I've tried rebooting, checked for proper grounds, and I replaced the dead battery in the control unit, but still no luck. Any information would be much appreciated. Thank you.
