Line Conditions
When using .50mm conductor cable, the maximum length of a line for an analogue telephone
is 1000m, and the maximum length of a line for a digital keyset is 400m.
Checking Power
In order to reduce operational problems with the DX-408/DX-408i systems due to mains
voltage drop and possible interruption of power, it is recommended that a separately fused
GPO be used.
Connect the DX-408/DX-408I digital key system to a dedicated GPO in order to
minimise noise problems or system malfunction due to mains voltage drops.
