X10 Slimfire Wireless Keychain Remote

The KR19A works with the TM751 Transceiver. It lets you turn on and off two individually coded X10 Modules and brighten and dim lights connected to Lamp Modules and Wall Switch Modules. In the default state (after first fitting the battery) the KR19A is set to House code A. The first (top) two ON-OFF buttons control modules set to Unit Code 1. The second (middle) two buttons control A2.
