3. WORKING PRECAUTIONS
The manufacturer is not responsible of any damage that can possibly happen to the
intercom master station outside the limits of the warranty or those produced by not taking care
with the working precautions.
Mains voltage must be between the limits of the admitted power supply (90-264
VAC, 50-60 Hz) and that the fuse must be the appropriate (2A slow blow type: T2A).
Damage caused by connection to improper AC voltage is not covered by any warranty.
DANGER: Inside the unit there are high voltages, do not open it. The unit does not
contain elements that could be repaired by the user. Whenever the intercom master
station is connected to the mains, it carries elements with high voltages. In order to
disconnect the unit completely, you must disconnect it from the mains.
CAUTION: Protect the unit from the rain and moisture. Ensure that no objects or
liquids enter it. If liquid is spilled into the unit, disconnect it from the mains and
consult a qualified service technician.
Do not place the unit close to heat sources.
