Technical

information

Environment

Your Response 15

should be kept free of

dust, moisture, high

temperature and

vibration. It 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.

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.

If the power fails

If the battery warning

light 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 light was on,

information may be

lost even if a back-up

battery was installed.

If no battery was

installed, all

information will be

lost and the Response

15 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 15

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 15 is used in

conjunction with 3

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.

If you have problems

with your machine,

call the Response 15
