Installation;
Never connect any terminals on the units to an AC power line.
When mounting the MFH-U/MFH-UB units in place of existing bell or chime, be sure to discon­
nect all wires from the present transformer.
Do not open the front cover of MFH-U/MFH-UB units, without first unplugging the power supply
from the AC outlet. The high voltage is loaded on the monitor unit inside.
Do not drop or apply any undue shock to the unit which may damage the picture tube.
Avoid running the connecting wires through doors, windows or in areas that may cause pinching
or disconnect.
The MFH-U/MFH-UB units must be installed in as dry and dust-free an environment as possible.
Installation location requirements;
Do not install MFH-U/MFH-UB video monitors in a place where they are
directly exposed to; direct sunlight, water, air conditioner, heater, chemicals,
frost, iron dust, vapor, etc.
Determine the installation height so that the center of the MFH-U/MFH-UB
video monitors will be at the convenient eye level: adults’ average height minus
100 mm (4").
Maintenance;
Clean your MFH-U/UB equipment with a soft cloth dampened with neutral
household cleaner. Never use lacquer thinner, benzine, etc.
