I bought this second hand,and for some reason the ' lock' facility
comes on erratically.It has not suffered any rough treatment.But when
re-sited,the ' lock' operated,and now when turning 'on' or 'off', or
using function buttons,the lock operates.
Anyone have any ideas? They would be appreciated.
I am trying to get the unit case off,but without success.Taken off the
obvious screws but this has'nt released anything.My idea is to get
inside and try and disable the 'lock' function.
Thanks.....T
