* Do not attempt to install or connect wires on LAF-C system while the system's power supply is plugged in.
* L-nAS add-on selectors and related equipment, unless specified as "weather resistant", are designed for indoor

* Any other manufacturer's products installed with the system (power supply, external signalling device, etc.) are
not covered under Aiphone's warranty.
* Do not mount L-nAS equipment in the following places, as it may cause the system to malfunction:
- High or extreme cold temperature areas: under direct sunlight, near equipment that varies in temperature,
in front of air conditioner, inside a refrigerated area, etc.
