It all depends on what kind of cables you have. The 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.
| Distance between the call station and the monitor | Cable to be used |
| Less than 80 m | 2 wires, 0.5 mm² minimum |
| Between 80 and 120 m | 2 wires, 0.75 mm² min. to 1.5 mm² max. |
