Setup
- Unpack the Blanket: Carefully remove the electric blanket and its components from the packaging.
- Position the Blanket: Lay the electric blanket flat on your bed, ensuring it is spread evenly without any folds or creases. The connectors for the controllers should be positioned near the bottom of the bed for easy access.
- Connect the Controllers: Locate the connectors on the blanket. Align the arrows on the blanket's connector and the controller's module. Firmly plug in the controller until it securely locks. For King size blankets, there are two independent controllers, one for each side.
- Plug into Power Outlet: Connect the power cord from the controller to a standard electrical outlet. Ensure the power cord (6 ft) and controller cord (10.5 ft) have sufficient length to reach the outlet without strain.
