Hi I changed the battery on my veritas r8 alarm as it was stuck with tamper light on following a power cut. I had hoped the new battery would get me back to normal. However, when I try to set my alarm it doesn't work. I have tried #### code to reset it but it is now stuck with number 1 to 8 solid red and the green unset button also lit. I cannot change the code either using the old code - 60 - new code - prog-reset but goes back to the 8 lights on again. Can anyone help me get it working again?
