Maintenance And Cleaning; Technical Specifications - Pro-Ject Audio Systems A1 Instructions For Use Manual

5. Maintenance and cleaning

Your record player requires little or no regular maintenance. Remove dust with a slightly moistened antistatic
cloth. Never use a dry cloth because this will create static electricity which attract more dust! Antistatic
cleaning fluids are available at specialist stores but must be applied sparingly to avoid damage to rubber
parts. It is recommended to fit the needle cover (i) before cleaning or maintenance is carried out to avoid
damage.
Always disconnect the record player from the mains power supply as a precaution before maintenance!
