Page: 16 / 48

If the fault is limited to one monitor or handset –
Assuming that the configuration and DIP switches have been checked first and are correct, the issue is
either the 1083/55 Distributor, the cable between the 1083/55 and the monitor/handset, or the
monitor/handset itself.
1. Rule out the monitor/handset - Swap the monitor/handset for a known working unit, not
forgetting to adjust the DIP switches.
2. Rule out the 1083/55 Distributor – Swap the 1083/55 for a known working unit.
3. Rule out the cable – Take the monitor/handset and connect it directly to the 1083/55
Distributor on a short new piece of cable.
