Maintenance Features:
The PDA69BU is designed with general maintenance considerations in mind, emphasizing safety and proper handling:
- Cleaning: The unit should be cleaned only with a dry cloth to prevent damage to internal components.
- Environmental Protection: To ensure longevity and safe operation, the device should not be exposed to rain or moisture, and should be kept away from heat sources such as radiators, heat registers, stoves, or other heat-producing apparatuses.
- Cable Protection: All wires connected to the unit should be protected from being walked on or pinched. When disconnecting the power cord, users should hold the plug, not pull the cord, to prevent damage.
- Power Off During Wiring: When wiring the unit and other connected equipment, it is crucial to ensure all equipment is turned OFF to prevent electrical hazards.
- Volume Control During Power On: After installation and wiring, all equipment should be powered on with volume and level controls turned DOWN. Volume should be slowly raised to proper positions once all equipment is ON.
- Grounding: Proper grounding of the unit is essential for safety and to maintain the built-in grounding features.
- Professional Servicing: In case of damage (e.g., damaged power cord, liquid spills, objects falling into the apparatus, exposure to rain/moisture, abnormal operation, or dropping), servicing should be referred to qualified service personnel. The cover of the unit should not be removed by unauthorized users as there are no user-serviceable parts inside.
- Hardware Inspection: Before placing, installing, rigging, or suspending the product, all hardware, suspension, cabinets, transducers, brackets, and associated equipment should be inspected for damage. Any missing, corroded, deformed, or non-load rated components must be corrected immediately to ensure safety. Only hardware rated for the specific loading conditions should be used, and the rating should never be exceeded.
- Regulatory Compliance: Users are advised to consult a licensed, professional engineer for physical equipment installation and to ensure adherence to all local, state, and national regulations regarding equipment safety and operation.
