Usage recommendations

Use the stylus on the touchscreen surface recommended by your device manufacturer and avoid exerting excessive sideways force on the tip. Keep the pen stored in its dedicated slot when not in use to maintain charge and protect the tip. If long continuous use is required, periodically rest the hand and verify device firmware is up to date for optimal compatibility.
