Mend Gardtec 800 Reset Change Code

How to reset gardtec 800?

In a fit of madness when my husband walked out I decided to change the code on the alarm. I didn't use it for a while and have forgotton the new code. Since then have had power out for a long period and the alarm is now making a beeping noise. There is a message Gardtech 800 V2.2. This noise is very annoying not only to me but the neighbours as well. Can someone please help me.

power down the system fully. power up the system within 5 seconds press 19 no yes and the sytem will revert the codes back to user 5678 and 07890 - off memory. if it does not work it must be the same as above but 19 yes no.

good luck
