Maintenance
Your Duet 450 Clock
Telephone should be
kept free of dust,
moisture, high
temperature, vibration
and should not be
exposed to direct
sunlight. It should not
be used in bathrooms
or near water.
Should the case of your
clock telephone
become soiled, it can
be cleaned with a warm
(not hot) soapy mild
detergent solution and
then dried. Stubborn
stains can be removed
by gently rubbing the
area with a very small
amount of alcohol on a
clean cloth. When
cleaning your clock
telephone in this way,
make sure it is turned
off and that the mains
power is switched off.
Do not use abrasive
cleaners as they can
scratch the surface of
your clock telephone.

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 Duet 450 Clock
Telephone has a REN
of 1. A total REN of 4 is
allowed. 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.
Mains Operation
For your own safety
and convenience your
Clock Telephone is
fitted with a UK BSI
standard 3 pin plug
with 3 Amp fuse.

mains plug should fail,
