TECHNICAL PRECAUTIONS

IMPORTANT:
• Aiphone Corporation is not responsible for improper installations of its product which result in interference generated by
dimmer switches, fluorescent lighting fixtures or other similar electrical devices. Any such installation must be corrected at the
source by the installing party. Aiphone also recommends that when installing any of its communication products that the
intercom wiring be run at least 20 inches (50 cm) away from any AC wiring.
• In an LEF/MK video system, run a separate LEF audio cable and MK video cable. Using the same cable for both audio and
video systems will cause severe interference with the LEF audio communications.
★ Clean your LEF equipment with a soft cloth dampened with neutral household cleanser.
Never use an abrasive cleaner or cloth.
