Technical information

You may find that your Freestyle 90 picks up conversations from other cordless phones being used nearby. If you experience this type of interference try changing channels using the CHANNEL SEEKER button on the handset.

Transmission frequencies

This cordless telephone has been designed to operate on radio frequencies which have been assigned to the exclusive use of cordless telephones. As the use of cordless telephones becomes more widespread, the quality of service obtained from this apparatus may lessen.

Transmission frequencies of available channels:

	Channels	Base Unit Tx	Handset Tx
		Freq./MHz	Freq./MHz

	4	31.1125	40.0125
	5	31.1375	40.0375

Ringer Equivalence Number (REN)

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 those sockets, to ensure that each telephone will 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.

Freestyle 90 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 unit. Even where the number of telephones has been limited, there is no guarantee that different types of telephone on the same line will ring.

Safety advice

•Don’t use your Freestyle 90 in the open air during thunderstorms. Unplug it from the telephone line and the mains socket when there are storms in your area.

•Don’t use your Freestyle 90 outdoors in the rain, or handle it with wet hands.
