Congratulations on purchasing the Zagg Slim Cover – the premier tablet keyboard and case for the Microsoft Surface™ Pro 3 and 4. Your new Zagg Slim Cover operates seamlessly with your Surface Pro 3 and 4 to give you more functionality, an easier typing experience, and added protection. Read these instructions completely and keep them in a safe place for future reference; and now, get ready to experience mobile typing that’s as versatile as you are.


Your Slim Cover keyboard pairs to your Surface via Bluetooth® 3.0. That means you can type on your keyboard without it being connected physically to your Surface. As an added feature, your Slim Cover keyboard can pair with two Microsoft devices at once for ultimate convenience. If the connection between your Surface and Slim Cover is ever lost, repeat these steps.

  1. Access the Bluetooth settings on your Surface.
  2. On your Slim Cover, press and hold for three seconds or depending on which one you want associated with your Surface. A blue LED will begin flashing, indicating your Slim Cover is in pairing mode.
  3.  Your Surface will display “ZAGG Slim Cover” as an available device. Choose it and then click Pair.
  4.  Repeat steps 2-3 to pair your Slim Cover to other devices. When paired with other devices, simply press or to toggle between them. Turning your Slim Cover Keyboard on is easy. Just press the Fn + (Delete) keys. A green LED will light, indicating your keyboard is on. To turn your Slim Cover Keyboard off, press the fn + (Delete) keys for two seconds. A red LED will flash indicating your keyboard is off.


Your Slim Cover keyboard features a battery that delivers up to three months of typing per charge*; and because the battery operates independent of your Surface, you can type on the Slim Cover even when it’s not physically connected to your Surface. Here’s how to charge your Slim Cover Keyboard:

  1. Plug the micro USB end of the included charging cable into the Slim Cover’s charging port – located on the right side.
  2.  Plug the USB end of the included charging cable into any USB charging outlet.
  3. The LED will light red and stay lit until your Slim Cover is fully charged.
  4. When the red LED goes off, your Slim Cover is fully charged. Unplug the charging cable and enjoy up to three months of the most spacious, natural typing available for your Surface.

Based on one hour of use per day. Using the backlit feature will reduce battery life and require more frequent charging.


Your Slim Cover can provide up to three months of regular typing per charge. Checking how much battery life it has left is easy – here’s how:

  1.  Press Fn + CTRL (also the battery key). The LED will light one of three ways.
    •  Three green flashes indicate a full battery.
    • Three yellow flashes indicate approximately half battery life remaining.
    •  Three red flashes indicate low battery life. When your Slim Cover reaches critical battery level the LED will flash red once every five minutes.

To help preserve battery life, your Slim Cover Keyboard will enter sleep mode if left on but not used for several minutes. To wake it, press any key. Also, the Slim Cover’s battery has no memory and may be charged whenever you wish.
