To maximize the lifespan of your Netset Pro-44 scanner, keep the unit away from extreme heat, moisture, and direct sunlight. If you plan to store the scanner for more than a month without use, always remove the internal AA batteries to prevent corrosive battery leaks from damaging the circuit board. Clean the exterior with a damp cloth; avoid harsh chemical solvents.
