We have an HKC alarm system with a SW-1070 panel, which allows you to hold the 'Rec/yes' button to record a short voice memo message for the next user, which you can also listen to via the 'Play/quit' button. Having done so though, how do you fully delete it after it has been used? Sorry if this is a silly question but I just can't work it out - and Google and the HKC website and manuals have been no help. Thanks.
