Gives an error

Hennie, May 2020

It sounds like you aren't logged on. Try pressing 1 then LOG. If it errors as soon as you press the numeric buttons, then you probably have lost everything from the machine in which case, a dealer will need to RAm clear it, replace the battery and setup the system areas ready for you to re-program it. this is common if the machine has been unplugged for a while.
