Hi, David
Recently got one of these too and very pleased with it so far, though not yet used in earnest.
I downloaded the YCE03 programming software from the Standard Horizon website to set it up via the laptop, makes life easier especially editing channel name tags and programming the directory:
Welcome to StandardHorizon.com
I notice there's also a firmware update 1.13 - mine has 1.11. Have you installed the update? I'm trying to find out what the differences are between the versions and also double-check that the firmware is ok for the E version.
cheers
Roger
