CM11 - how to clear the memory ??

["egelbeertje" <r_d_k@xxxxxxxxxxx>]

Hi,

Finally acquired this unit after long debating it being worth it but
in the end figured it will do for the moment.
Been fiddling with it over the weekend and suddenly got "Insufficient
Memory in the Interface" error. Can't get it cleared and can't upload
new timers.

All advise welcome (obiously I already left it unplugged overnight
without batteries but to no avail.)
