Model:
AVR-TRC-AGILE 1000/2000/3000/5000/10000-WL
7. MAINTENACE
This AVR is basically maintenance free! But regular maintenance can extend the life span of the AVR by the following
steps:
Regular inspection
• Disconnect the AVR from the mains power completely.
• Use cotton cloth and detergent to clean the body and ventilation holes.
