BT On-Air DECTf@x Plus F@x machine and digital telephone system manual Technical information

Technical information

This product is intended to be connected to analogue networks and private switching systems in the United Kingdom.

This equipment complies with the essential requirements of the Radio Equipment and Telecommunications Terminal Equipment Directive, 1999/5/E

Choosing a position

Your On-Air DECTf@x Plus should be kept clear of dust, moisture, high temperature and vibration and should not be exposed to direct sunlight. Don’t install it close to radiators or air-conditioning outlets or in excessively warm, humid or dusty places.

WARNING

The apparatus is designed to be operated only in a normal office or domestic environment where the relative humidity does not exceed 60%. It should not be used in bathrooms or near water.

How many phones you can have

Your exchange line provides only a small current to make your telephone ring. Although you may have any number of sockets it is important to limit the number of telephones and other items of apparatus connected to the line by these sockets. This ensures that each telephone will receive enough current to ring.

Every telephone or item of apparatus has a Ringer Equivalence Number (REN). In most cases a standard line should provide enough current for two or more telephones or items of apparatus, if the REN’s add up to no more than 4.

On-Air DECTf@x Plus has a REN of 1. Any telephone provided by BT may be assumed to have a REN of 1 unless otherwise stated on the base. Even where the number of telephones has been limited, there is no guarantee that the different types of telephone on the same line will ring.

Safety warnings

WARNING

This equipment is not designed for making telephone calls when the power fails.

Alternative arrangements should be made for access to emergency services.

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

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.
