Quote"Hi Steve your panel is fitted with a NVM chip, which is designed to retain all information programmed inc your code, the reason why the panel has reverted back to 1234 factory conditions is because your battery is dead and the NVM is only good for about 10-15 years
Down-load a user manual to reset your code and buy a new Yuasa 2.1 amp rechargeable lead acid battery,
Problem will now be sorted,

And the programming will be lost as the time and date stamp. In fact everything that makes your alarm work out of the box and no doubt not how it was programmed to meet your or previous owners needs.
