Technical information
Environment
Your Diverse 3010 Micro 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 other surfaces which
generate fibres or place it in locations which
prevent the free flow of air over its surfaces.
If the power fails
This equipment is not designed for making
emergency calls when the power fails.
Alternative arrangements should be made for
access to emergency services.
How many phones can you have?
All items of telephone equipment have a
Ringer Equivalence Number (
REN ), which is
used to calculate the number of items that may
be connected to any one telephone line. The
Diverse 3010 Micro has a REN of 1. Any other
instrument provided by BT may be assumed to
have a REN of 1 unless stated otherwise. A total
REN of 4 is allowed. (For example: if Diverse
3010 Micro is used in conjunction with three
extension telephones, each with a REN of 1,
the total REN is 4.)
Approval
Connection to the BT telephone network.
Diverse 3010 Micro is fully approved for
connection to the BT network provided it is
used according to the instructions in this guide.
The telephone lines must provide Loop
Disconnect (Pulse) or Multi-frequency (Touch
Tone) dialling capabilities.
It may be connected to Direct Exchange Lines
and switchboards (PBXs) with new plan
(plug and socket) arrangements. It may not be
connected to shared service (party line)
installations.
Connecting to switchboards.
Diverse 3010 Micro is only approved for use
with a compatible switchboard including those
which do not provide secondary proceed
indication. Even if you do have a compatible
switchboard, it cannot be guaranteed that the
telephone will operate correctly under all
possible conditions of connection.
This equipment complies with the essential
requirements for the Radio Equipment and
Telecommunications Terminal European
Directive (1995/5/EC).
WARNING
The apparatus is only designed to be
operated in a normal office or domestic
environment where the relative humidity
does not exceed 75%. It should not be
used in bathrooms or near water.
Note
All additional Diverse handsets have a
REN of 0 and therefore if you have six
handsets registered to a Diverse 3010
base station then the REN No = 1.
