The Slate uses magnetic detection technology that requires certain conditions for optimal performance. The principal factors that can affect Slate's precision are:
- Magnetic objects such as telephones, speakers, motors, magnets, computers, or metal bars in the surrounding environment
- WiFi or other Bluetooth radio signals that can interfere with the communication between the Slate and your iPad while using the Slate in Bluetooth mode
For best results, keep all magnetic objects at least 10 inches or 25 centimeters from the Slate to make avoid interference with the magnetic field. Make sure that you do not place the iskn pen on the Slate when you turn on the Slate.
