Dave,

I haven't tried the codes yet, but it looks like your
iMon remote is different to mine. Mine has buttons yours
does not and vice-versa (mine for example has buttons
like My DVD, My Music etc.). I wonder if this is the same
remote (unfortunately, mine has no identifying markings,
other than a serial number inside the battery compartment).

I wonder if some LC20M cases are shipped with different
remotes (US vs. UK version perhaps)?
