Setting up your telephone
Connection and conditions for use
You can connect your SD8101 to a direct exchange line (DEL), a line
connected to a local exchange, with its own phone number; to an extension
socket connected to a DEL; or to an extension on an approved compatible
PBX. Do not connect the SD8101 as an extension to a payphone.
How many phones can you connect?
The ringer equivalence numbers (RENs) of all instruments (phones, fax
machines, etc.) connected to an exchange line must not add up to more
than 4, otherwise, one or more of them may not ring and/or answer calls
correctly. The SD8101 has a REN of 1, and most other telephones have a REN
of 1unless marked otherwise.
Radio signals between handset and base unit
To use your handset and base unit together, you must be able to establish a
radio link between them. Be aware that:
•
Sitting the base unit as high as possible will give better results, in a
two-storey house, the best position may be on the first-floor landing.
•
Any large metal object, like a fridge, a mirror or a filing cabinet,
between the handset and base unit may block the radio signal.
•
Other solid structures, like walls, may reduce the signal strength.
Choosing a site for the base unit
The base unit should be placed on a level surface, in a position where:
•
The mains adapter plug will reach a 230-V AC switched mains supply
socket; never try to lengthen the mains power cable.
•
The telephone cable will reach your telephone line socket or
extension socket.
•
It is not close to another telephone, this can cause radio interference.
•
It is not close to a sink, bath or shower, or anywhere else where it
might get wet.
•
It is not close to other electrical equipment, fridges, washing
machines, microwave ovens, TVs, fluorescent lights, etc.
