Handheld Transmitter Modules
These modules work wirelessly and therefore require an RF-to-X10 gateway within range. Otherwise, they perform the
same task as the tabletop transmitter modules, except they need batteries to power them.

Handheld RF Remote (HR10U)
These are comparatively cheap devices, capable of controlling all 16 devices in any given house code. They support
brightness control but not “all lights on”/“all units off,” and they have arranged the buttons in an on/off order, rather
than the more geek-logical off/on.
One useful trait of this device is that it has a strip of card on the left side onto which you can write the names of the
appliances that each button controls. Other than that, it's a fairly straightforward device that “does what it says on the tin.”
