Hello I would try to reinstall this unitInstallation: 1. Install 4 AAA Batteries into the Remote Controller, careful to point batteries in the correct direction. 2. Rotate the House Code Dial on the face of the Remote to the desired Letter matching all the installed Module s. 3. Set the RF Handheld Remote Slide Switch to (1-8) to operate Units 1-8 or set it to (9-16) to operate Units 9-16. 4. Plug in and set the (TM751) RF Base Transceiver's House Code Dial to match the House Code on the RF Handheld Remote that will be used. 5. Set the UNIT Slide Switch to "1" to control the built-in Outlet, from a Wireless Transmitter or Controller sending an X10 "A1" Command, or set the Switch to "9" to control the built-in Outlet with an X10 "A9" Command. The UNIT Slide Switch has no effect on control of all 16 Unit Numbers from the X10 PRO Handheld Remote Control (HR12A).IF no luck then you can reach manufacture tech support at Call 1-888-384-0969, visit www.x10.com, or email support@x10.com
