★ High voltage is present on the monitor unit inside. Do not open MYH-CUB without first unplugging the power
supply, to prevent electric shock.
★ Do not attempt to install or connect wires on MYH-CUB equipment while system’s power supply is plugged in.
★ MYH-CUB and related equipment, except door station, are designed for indoor use only. Do not install outdoors.
★ Do not connect any other power source than specified on terminals -r, -. Doing so can damage the MYH-CUB
