Safety Instructions

Always read and follow these safety guidelines to prevent electric shock, fire, or hearing damage:

• Use only high-quality professional speaker cables with 1/4" TS or twist-locking plugs.
• Do not remove the top cover or rear section; there are no user-serviceable parts inside.
• Do not expose the apparatus to rain, moisture, or dripping liquids.
• Ensure the device is connected to a mains socket with a protective earthing connection.
• Operating temperature range is 5° to 45° C (41° to 113° F).
• Do not listen at high volume levels for long periods to prevent hearing damage.
