Setup Instructions
- Unpack the Blanket: Carefully remove the heated blanket and controller(s) from the packaging.
- Position the Blanket: Lay the heated blanket flat on your bed, ensuring it is evenly spread and not bunched or folded. The connector for the controller should be positioned near the head of the bed for easy access.
- Connect the Controller: Locate the connector on the blanket and the corresponding plug on the controller. Firmly push the controller plug into the blanket connector until it clicks securely into place. For King size blankets, there are two controllers and two connectors, one for each side of the bed.
- Connect to Power: Plug the controller's power cord into a standard 110-volt AC wall outlet. Ensure the outlet is easily accessible.

Operating Instructions
Your Serta heated blanket features a programmable digital controller and dual controls for King size, allowing independent heat settings for each side of the bed.
- Power On/Off: Press the Power button on the controller to turn the blanket on or off. The display will illuminate when on.
- Adjusting Heat: Use the Temperature Up and Temperature Down buttons to select your desired heat level. The digital display will show the current setting.
- Setting Heat Time: Use the Timer button to set the desired operating time. The blanket will automatically shut off after the set time, or after 10 hours if no time is specified.
- Pre-Heat Feature: To quickly warm your bed, activate the pre-heat function. This feature rapidly heats the blanket to your selected temperature and then maintains it. Refer to your controller's specific instructions for activating pre-heat.
- Dual Control (King Size): Each controller operates its respective side of the King-sized blanket independently. This allows two users to customize their warmth settings without affecting the other.
