It all depends on what kind of cables you have. The V®350 & V®500 Connect requires electrical cables, not telephone cables.

The diameter of the cables to be used also depends on the distance between the call station and the monitor:

• Less than 80m: 2 wires, 0.5 mm² minimum
• Between 80 & 12m: 2 wires, 0.75 mm² min. to 1.5 mm² max.
