Voltage Drop
The voltage drop introduced between the PSTN and the associated telephone is 2.0 Volts so therefore no additional series equipment may be connected. The introduction of this voltage drop may occasionally cause difficulties in making calls from the associated telephone or problems in telephone conversation being experienced by both parties to the call.
While operation may be possible initially, change to or modernisation of the network taking place in the normal course of events may result in the apparatus being connected to be compatible, failure of the apparatus to work under these circumstances may not be the responsibility of the network operator.
In the unlikely event of such problems occurring, the user should contact the supplier or maintainer of the apparatus.
Note
The definition of RBS (Relevant branch system) for PSTN lines is given in BS6789 section 6.1 (1986) clause 2.4.

Alternative arrangements should be made for access to emergency services.
Technical information
Safety warnings
1Interconnection circuits should be such that the equipment continues to comply with the requirements of 4.2 of EN 41003 for TNV circuits and 2.3 of EN 60950 for SELV circuits, after making connections between circuits.
2Interconnection directly, or by way of other apparatus, of ports marked “Safety Warning. See instructions for use” with ports marked or not so marked may produce hazardous conditions on the network. Advice should be obtained from a competent engineer before such a connection is made.
3When you operate this equipment, the electrical mains socket should be near the equipment and be easily accessible.
Warning
To prevent fire or shock hazard, do not expose this product to rain or any type of moisture.
How to connect the mains lead to a plug
Your apparatus comes complete with fitted plug. If however, it becomes necessary to fit an alternative mains plug, the following instructions must be adhered to.
Note
The wires in the mains lead are coloured in accordance with the following code:
Blue: Neutral
Brown: Live
Read the instruction carefully before connecting the mains lead to a plug. If in doubt, consult a qualified electrician.
As the colours of the wires in the mains lead of the apparatus may not correspond with the coloured markings identifying the terminals in your plug, proceed as follows:
•The wire which is coloured blue must be connected to the terminal which is marked with the letter N or coloured black.
•The wire which is coloured brown must be connected to the terminal which is marked with the letter L or coloured red.
