Power For Slimline Switch
Why doesn't the Slimline switch turn on my lights?
Why doesn't the light on the switch light up?
Check the battery in the SlimLine Switch.
This switch does not send a direct signal through the house wiring to control any module, so it uses batteries to send a radio frequency command to your transceiver.
The battery compartment is in the bottom-center of the unit and just pulls straight out.
Make sure the compartment closes securely again.
