•When mounting each card, fully insert it into the Main Frame. After all cards are mounted, secure them with the card fixing bracket.

•When the unit gets dirty with dust or oil, wipe down with a soft, dry cloth. Never use a chemically-treated cleaning cloth or volatile liquids, such as benzine and thinner, because the unit's plastic parts may be deformed or its finish discolored.

•All units except the AI-RS170 and AI-RS180 Substations are designed exclusively for indoor use. Do not install them outdoors.

•The whole system will not operate without power supply.

•In areas where broadcasting stations are close by, the system operation may be affected by radio frequency interference.

•Keep DC wiring at least 30 cm away from AC wiring. Otherwise, the system may malfunction.
