Do not try to use any power
adaptor except the one provided
(item code 870965) otherwise
you may permanently damage
your Response 65 Caller Display
and this will invalidate the

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.
Technical
information
If the power fails
• If the battery-low LED was not lit before
the power was lost, all information
should be retained for at least one hour
(up to 6 hours for a fresh alkaline
battery).
• If the LED was lit, data may be lost even
if a battery was installed.
• If no battery was installed, all
information will be lost and the
Response 65 Caller Display will power
up as new when power is restored.
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.
Your Response 65 Caller Display 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 your Response 65 Caller
Display is used in conjunction with three
extension telephones, each with a REN of 1,
the total REN is 4.)
If the total REN of 4 is exceeded, the
telephones may not ring. With different
telephone types there is no guarantee of
ringing, even when the REN is less than 4.
Environment
Your Response 65 Caller Display 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.
