Environment
Your Callscape unit should be kept free of
dust, moisture, high temperature, vibration
and should not be exposed to direct sunlight.
Do not stand it on carpets or on other
surfaces which generate fibres, or place it in
locations which prevent the free flow of air
over its surfaces.
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.
Each 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 RENs add up to no
more than four.
Callscape has a REN of 1.
Warning
The apparatus is only designed to be
operated 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.
Callscape must only be used with the power
adaptor supplied with it.
